The correct height and weight of a woman. How to calculate your ideal weight. Corrective massage is
There is no limit to perfection, as you know. This is especially true of the standards of female beauty. Especially many young ladies are concerned about the question of what should be the ideal ratio of height and weight. To get closer to the ideal, girls torture themselves with various diets and spend many hours in gyms.
Nevertheless, not every young lady is able to immediately answer the question of what should be the weight with a height of 170 or 158 centimeters. Here you have to do some calculations. There are different methods.
What should be the ratio of height and weight
To be honest, the norm of weight and height for women is a very individual indicator, because there are many additional parameters. For example, someone has a so-called broad bone, while someone has a highly developed muscle mass. To find out for growth, all these data must be taken into account. Also, the measurements will be quite approximate for those who have not yet finished growing (teenagers), as well as for women who are in an “interesting position”. In these cases, there is no need to talk about ideals at all.
How to determine your height correctly
The first step is to properly measure your own height. To do this, stand with your back to a sheer wall and lean against it. You must have at least five touch points:
- back of the head;
- protruding parts of the blades;
- buttocks;
- calf muscles;
- heels.
If at least one of these points you do not touch the wall, then you are standing incorrectly. In this case, the measurements cannot be considered quite correct.
Place a flat plank, ruler, or book on top of your head and have someone draw a line where the object touches the wall. Now, using a measuring tape, measure the distance from the floor to the mark. The result can be evaluated as follows:
- 150 cm and less - low growth;
- 151-156 cm - below average;
- 157-167 cm - average height;
- 168-175 cm - high;
- 176 cm is very tall for a woman.
What should be the weight with a height corresponding to the measured one, special tables will help you find out. However, this result cannot be considered quite correct. The fact is that not every table takes into account all the necessary parameters.
Body types: what are they
The proportions of weight and height in women depend on many parameters, for example, there are three types of them:
- Asthenic. Another name is thin-boned. People of this type have very thin, long and fragile limbs. Their growth is usually above average. They also have rather narrow hips and shoulders, as well as a small chest. Asthenics most often have an accelerated metabolism, so they are rather thin. If people of this type begin to eat a lot, then the weight will increase very slowly. They say about such people: "a boyish figure."
- Normosthenic - normal. Such young ladies are the luckiest, since everything is proportional in their body: the bones are of medium thickness, the shoulders and hips are quite wide, and the waist is much narrower compared to them. The metabolism of this type of women is moderate. With a normal diet, all kilocalories are completely consumed, but you should not overeat, because there is a risk of spoiling the figure quite quickly.
- Hypersthenic - wide bone. In this type of people, the bones are quite wide and massive. Outwardly, this is clearly visible: wide hips and shoulders, a short neck and legs, a massive chest. This type is the most unlucky. The metabolism of such people is slowed down, and with improper nutrition, the mass will be gained at lightning speed.
Since the norm of weight and height for women depends primarily on the type of physique, it is necessary to correctly determine it. To do this is quite simple. To do this, you just need to measure the circumference of your wrist. Since this is the only part of the body on which fat is practically not deposited, such measurements can be trusted. So:
- 16 cm or less - you are an asthenic;
- 16-18.5 cm - you have a completely normal body type;
- 18.5 cm or more - you have a wide bone.
Leg length
In addition to the correct ratio of weight and height, it is also important for a beautiful figure to have good proportions. Since growth mainly depends on the length of the legs, this parameter is also important. Of course, the length of the legs is quite difficult to fix, you will have to be content with what nature has given.
Usually there are asthenic young ladies or women of the normal type. Legs should be measured from the floor to the protruding tubercle (if there are no problems with weight, then it is clearly visible).
For the figure to be considered proportional, the length of the girl's legs must be at least half the height. It is considered beautiful to have parameters at which the length of the legs is more than 1/2 of the height by several centimeters:
- 2-4 cm - for hypersthenics;
- 4-6 cm - for a normal physique;
- 6-9 cm - for asthenics.
If nature does not spoil you with long legs, then this shortcoming can be corrected by the presence of high heels.
Age also needs to be taken into account.
In addition to these factors, it is also necessary to take into account the age of the woman. The fact is that the norm of weight with a height of 175 for women who have celebrated their fiftieth birthday and twenty-year-old girls will be different. It has to do with the metabolic rate. The younger the girl, the higher he is. Accordingly, the rules differ.
How to determine the correct ratio of your weight and height
To do this, there are many different formulas and tables that take into account various factors. Which one to choose is up to you. To determine your ideal weight for height yourself, you can use, for example, Brock's formula. The calculation will be quick, but quite approximate. To do this, you just need to correctly measure your own height and subtract 100 cm from the result obtained in centimeters. This will be the desired weight.
As you understand, the norm of weight and height calculated in this way for women is very approximate, because the calculation does not take into account either the type of physique or, in fact, the age of a person. Therefore, to adjust the result, you can safely take away another 7-10%.
Quetelet formula
Those who are interested in the norm of weight and height for women can use, for example, the Quetelet formula, which takes into account all the necessary parameters. The formula is not too complicated, anyone can apply it:
- M \u003d 0.75 x (P - 150) + 50 + (B - 20): 4.
All letters here are intuitive: M - body weight; B - age; P is the height of a person.
To make an additional check, you can also calculate BMI (in the English version of BMI), which stands for or in another way. It is very simple to do this:
IR \u003d B: R 2.
The letters, of course, indicate weight and height, respectively, only in this case, height must be measured in meters. Depending on what number you got, we evaluate the results:
- 18.5 and less - you have a clear weight deficit, you urgently need to gain a few kilograms;
- 18.6-24.9 - your weight can be considered normal, there are no medical indications for weight loss;
- 25-29.9 - sad, but your weight cannot be called normal, therefore, for good health and a beautiful figure, you still need to lose a couple of kilograms;
- 30-34.9 - you have obvious signs of obesity of the first degree; if you do not want to have a lot of health problems, then urgently go to the gym;
- above 35 - obesity of the second degree; most likely, in the near future you will need the help of a doctor, since with such a weight, health deteriorates significantly;
- above 40 - you just need the help of a nutritionist, you are unlikely to be able to lose weight on your own.
Norm of weight and height: table for women
Since all the ratios of the parameters of the human body have long been calculated by nutritionists and simply indifferent enthusiasts, you can determine your personal ideal weight using one of the many ready-made tables. To get the most accurate result, choose tables that take into account the largest number of parameters. When using them, it is worth remembering that for men and women the data is most often different, so be careful.
There is another very simple and affordable way to determine if it's time for you to lose weight. Divide your waist measured in centimeters by your hips. If the result is less than 0.8 - everything is in order, you do not need a diet. Those who have indicators ranging from 0.81 to 0.84 should think about their diet. Well, for those who have this figure greater than or equal to 0.85, it's time to see a nutritionist - you are obese.
The results of BMI calculations are not suitable for assessing the weight of professional athletes, pregnant women, as well as people suffering from edema and other disorders that lead to an incorrect assessment of the original data.
Weight ranges in this calculator are calculated taking into account height, according to the methodology of the World Health Organization (WHO).
The very method of estimating weight by BMI is intended for the primary detection of underweight or excess weight. Obtaining an estimate different from the norm is the reason for contacting a nutritionist and endocrinologist in order to conduct an individual weight assessment and make recommendations for its correction, if necessary.
Range ideal weight(norm) shows at what weight the probability of occurrence and recurrence of diseases associated with overweight or underweight is minimal. In addition, as practice shows, a person with normal weight looks not only healthy, but also the most attractive. If you adjust your weight, it is highly recommended not to go beyond the norm, in order to avoid health problems.
About weight categories
underweight usually an indication for increased nutrition; consultation with a dietitian or endocrinologist is also recommended. This category includes people who are malnourished or have a disease that leads to weight loss.
Underweight is also typical of professional models, gymnasts, ballerinas or girls who are overly fond of weight loss without the control of a nutritionist. Unfortunately, this can sometimes lead to health problems. Therefore, weight correction in this range should be accompanied by regular medical supervision.
Norm shows the weight at which a person has the maximum chance of staying healthy as long as possible, and, as a result, beautiful. Normal weight is not a guarantee of good health, but it significantly reduces the risk of disorders and diseases caused by overweight or underweight. In addition, the owners normal weight, as a rule, are in good health even after intense physical exertion.
Preobesity speaks of being overweight. A person in this category often has some signs associated with excess weight (shortness of breath, increased blood pressure, fatigue, fat folds, dissatisfaction with the figure) and has every chance of moving into the category of obesity. In this case, a slight weight correction to the norm, or to values close to it, is recommended. It also does not hurt to consult a nutritionist.
Obesity- an indicator of chronic disease associated with excess body weight. Obesity invariably leads to problems with the cardiovascular system and significantly increases the risk of acquiring other diseases (diabetes, hypertension, etc.). Obesity is treated exclusively under the supervision of a nutritionist or endocrinologist, and only after the necessary tests have been carried out and its type has been determined. Uncontrollably engaged in diets and serious physical activity with obesity is not recommended, as this can provoke additional problems.
Answers on questions
What is the ideal weight for me?
The calculator calculates a weight range that is ideal for you based on your height. From this range, you are free to choose any specific weight, depending on your preferences, beliefs and requirements for the figure. For example, adherents of a model figure tend to keep their weight on the lower border.
If your priority is health and longevity healthy life, then the ideal weight is calculated based on medical statistics. In this case, the optimal weight is calculated based on a BMI of 23.
Can you trust the resulting estimate?
Yes. Adult weight estimates are based on the results of authoritative research by the World Health Organization (WHO). Weight assessment from birth to 18 years is made on a separate basis. special technique also developed by WHO.
Why is gender not taken into account?
The BMI of adults is assessed in the same way for both men and women - this is justified by the results of statistical studies. At the same time, for weight assessment, gender and age are of fundamental importance.
Some other weight calculator gives a different result. What to believe?
There are a huge number of calculators designed to give an estimate of weight based on height and gender. But their formulas, as a rule, were developed in the last century by individuals or groups based on criteria that are unknown to you or do not suit you (for example, formulas for evaluating athletes).
The WHO recommendations used in this calculator are developed for ordinary modern people, taking into account the conditions of modern life, advances in medicine and based on recent observations of the population of all continents of the planet. Therefore, we trust only this technique.
I think the result should be different.
Evaluation is based solely on the height and weight you provide (and age and gender for children). In case of unexpected results, please double-check all entered data. Also, make sure that you do not belong to any of those whose weight cannot be assessed through the body mass index.
My result is underweight, but I want to lose more weight
There is nothing unusual in this, many professional models, dancers, ballerinas do just that. However, in this case, it is recommended to lose weight only under the supervision of a nutritionist and endocrinologist, so as not to harm your health. if it means something to you.
Please note that the body of most people is not able to fully function in a state of deficiency of body weight. And only a few, due to the peculiarities of genetics (or disease, ecology, lifestyle) can live comfortably with a lack of body weight: without health risks and without experiencing malaise, dizziness and constant hunger.
My result is normal, but I consider myself fat (or thin)
If you have concerns about your figure, then we recommend that you go in for fitness, having previously consulted a good nutritionist.
Please note that some elements of the figure are almost impossible to correct only with the help of fitness, exercise, diet, or a combination of both. Your goals should be analyzed by an experienced doctor in order to assess their reality, consequences and prescribe only the right procedures.
My result is pre-obesity (or obesity), but I do not agree with this
If you are an athlete (or amateur weightlifter) with increased muscle mass, then BMI weight assessment is simply not intended for you (this is mentioned in). In any case, for an accurate individual weight assessment, contact a nutritionist - only in this case you will receive an authoritative result with a doctor's seal.
Why am I considered too thin or fat even though my weight is normal?
Pay attention to the personality and weight of those people who bother you. As a rule, they judge exclusively by themselves: subjectively. Fat people always consider thin people to be skinny, and thin people consider fat people to be fat, moreover, both of them can have a healthy weight. Take into account social factors: try to exclude, stop or ignore those judgments in your address that are based on ignorance, envy or personal hostility. Only an objective assessment of BMI is worthy of trust, which clearly indicates the norm, excess or deficiency of mass; and trust your worries about the figure only to supportive people of your weight category, and preferably an experienced dietitian.
How to calculate body mass index (BMI)?
It is necessary to divide the weight indicated in kilograms by the square of the height indicated in meters. For example, when growing 178
cm and weight 69
kg calculation will be as follows:
BMI = 69 / (1.78 * 1.78) = 21.78
There is hardly a person who would not care about him appearance. Each of us wants to look attractive - to have ideal body proportions, maybe even become a new standard of beauty. But, as you know, we are all different - in height, age, configuration.
In many ways, a person’s self-awareness is affected by his weight. Accordingly, the higher it is, the more uncomfortable we feel. It is unlikely that there is a person who refuses to calculate the ideal weight for him. As mentioned earlier, we are all different, which means that body weight will be individual.
Ways to calculate ideal weight
We are not alike, and each has its own beauty. And in pursuit of perfect figure it would not hurt to know the exact weight to which it is necessary to strive. So it will be easier to control the path traveled and the remaining path to your standard.
When calculating your ideal weight, remember that you should first of all feel comfortable with these kilograms. Because someone is crazy about protruding collarbones, while others, on the contrary, prefer curvaceous forms.
Despite all individual preferences, doctors have set a peculiar framework for determining the shortage or excess of kilograms. To date, a great many online calculators and various tables have been developed and compiled. Many experts are studying the question of how to calculate weight by height and age, gender. But they did not come to a consensus.
The most famous calculation methods:
- By Quetelet
- By Brock.
- According to Egorov-Levitsky.
- According to Lorenz.
You can independently calculate weight by height and age using any of the methods. And having learned the treasured figure, it will be possible to begin the path to your standard.
Calculation of BMI by Adolf Quetelet
It is worth immediately warning that this method will not calculate the ideal weight. According to Quetelet, based on your current weight and height, you need to calculate After, focusing on the result and the developed table, get information about the need to gain weight or lose weight.
This scientist calculated the body mass index by the formula: weight, kg / (height, m × height, m).
Age 18-25 years old | Age 26-46 years |
|
Inadequate |
||
Underestimated, but not critical |
||
Excess |
||
27.5 and above | Obesity |
|
Example: a woman at the age of twenty-seven, one hundred and seventy centimeters tall and weighing sixty-seven kilograms. BMI = 67 / (1.7 × 1.7) = 23.18. According to the table, the index indicates weight within the normal range.
The Quetelet method is not exactly a calculation of weight for any height. Since the formula for calculations is only suitable for the average person (170-190 cm for men and 155-175 for women). If you are constantly moving and exercising in the gym, this calculation method is also not suitable for you. The advantage of BMI is that it does not push a person on the path to an invisible ideal, but assesses the real state.
Calculation of the ideal weight according to Brokk
Paul Brokk is a French surgeon and anthropologist. The formula by which it is possible to calculate the weight of a person, he invented in 1871. You can apply it for people with a height of one hundred and fifty-five to one hundred and seventy centimeters. Also a condition for the calculation is the possession of an average physique. Formula for women: weight = height, cm - 100. Then multiply the resulting figure by 0.85. For men, also subtract a hundred from height. And the result is multiplied by 0.9.
For example, for a woman with an average build and a height of 170 centimeters, the ideal weight would be 59.5 kilograms ((170 - 100) × 0.85 = 59.5).
Updated calculation according to Brokk
After some time, the formula was improved. Since the previous version required a person of average build, growth in a certain interval, people with a non-standard figure could not enter this category. For example, with heavy bone or bulky muscles. After processing by scientists, the Brocca method became more real and reliable:
- for women: weight = (height - 110) × 1.15;
- for = (height - 100) × 1.15.
For example, the calculation of the ideal weight for a woman one hundred and seventy centimeters tall will look like this: (170 - 110) × 1.15 \u003d 69. Sixty-nine kilograms is the optimal weight for the weaker sex with a non-standard figure.
Lorenz ideal
The scientist developed the formula exclusively for the representatives of the beautiful half of humanity, these calculations will be inappropriate for the stronger sex. The calculation of the ideal body weight is as follows: (height - 100) - (height - 150) / 2 = body weight.
Example: a woman is one meter seventy centimeters tall. The calculation will look like this (170 - 100) - (170 - 150) / 2 \u003d 70 - 20 / 2 \u003d 60. So, according to the Lorentz formula, for a representative of the weak half of humanity, the ideal weight would be sixty kilograms.
Compared to Brokk's calculation, Lorenz has more stringent requirements for body weight. This formula is more suitable for eighteen-year-old girls. And if the proposed figure does not quite suit you, just forget about it and use the formula of another scientist. And plus everything, the calculation is not suitable for women above 175 centimeters.
Egorov-Levitsky method
No weight calculation formula is needed for this method. The scientist created a table indicating the maximum body weight, taking into account age and
When compiling, the developers took into account all the most important factors that form the weight. They indicated only the maximum limit, but did not specify the minimum. And, in fact, it is not necessary. After all, a person is mainly concerned about excess kilograms, and not their lack.
How to achieve your ideal weight
If, after you have calculated the weight by age, height and gender, you find that there are a couple of extra pounds, then it's time to think about eliminating them.
Trying to maintain an ideal body weight, you are doing a huge service to your body. In many developed countries, overweight people make up fifty percent of the total population. And every year their number increases exponentially. This is an additional, unnecessary burden on the human body. It affects the joints to a greater extent and internal organs. But, nevertheless, it is worth noting that thinness also does not benefit. The golden mean in the matter of weight is what any person needs.
Once you've made the decision to lose weight, don't try to find a miracle-working fast diet. Such does not exist. It will not bring benefits, but it is quite capable of weakening the body. It is best to lose weight gradually. Indeed, get rid of excess weight not difficult, difficulties appear when trying to hold it.
A weight loss method is considered safe, in which you lose from five hundred grams to one kilogram per week. If the weight goes off faster, then you burn not only fat, but also muscle fibers. And this is absolutely unacceptable. Since with well-developed muscles it is easier to maintain optimal weight.
Steps to ideal weight:
- Drink a glass of clean drinking water on an empty stomach, and fifteen minutes before the start of any meal.
- Don't skip breakfast. And no, you shouldn't skip any meal. After all, this way you will get hungry and eat even more next time. And, as you know, it is better to eat many times, but a little bit.
- Try to reduce your fat intake.
- Come to the store with a prepared shopping list. So you will not be tempted to grab something unnecessary and harmful.
- Chew food thoroughly. Thus, you not only do not choke, but also get enough faster. When eating slowly, the feeling of hunger disappears more quickly.
- If you feel like you haven't eaten enough and need a refill, then the first thing you need to do is take your time. Sit for five minutes. And then think about whether the feeling of hunger is really so strong.
- Eat strictly in the kitchen. Never eat while standing or walking.
- Add a fresh fruit or vegetable to every meal.
- Avoid white bread.
- Simmer and bake. Try not to fry your food.
- Allow yourself sweetness no more than once a week.
- Give up fast food.
- The optimal number of meals per day is five.
- Cook your own meals more often. So you will control how it is processed and calories.
There is such a value that differs for women and men as the weight and height index (BMI), which helps to assess the correspondence of a person’s mass with his height.
It helps to identify excess, normal or missing weight, which is very important if you need to treat the body or to self-correct your figure.
Back in the 19th century, doctors determined that the appearance of diseases is directly related to the presence of fatty matter in humans. To determine the optimal weight, it was necessary to calculate the ratio of human height to its weight.
In 1869, the doctor A. Quetelet invented a method for calculating the index, which allows you to assess how much body weight fits the existing height. Over time, many scientists have made various corrections and new formulas have appeared. But the rules have varied over time.
Recently, the optimal BMI has decreased, and this has led to an increase in the number of people who are overweight and obese.
Optimal body weight - the established range within which weight can move without affecting the functioning of the body
How is BMI determined?
Sometimes, the calculation of BMI does not provide accurate data. This is due to the fact that people have a different ratio between muscle and fat mass, which is due to many factors. Therefore, individuals with the same indicator do not look the same.
For a correct calculation of BMI, age, gender and type (thin-boned, medium-boned and wide-boned) build, established based on measurements of the girth of the wrist, are taken into account.
An objective value is considered to be the proportion expressed as a percentage between fat and musculoskeletal tissue for women - 13-20%, for men - 10-15%.
Thin people with narrow bone formation have a lower standard compared to owners of large forms. Sometimes, to determine the constitution of the body, the volume of the chest is measured.
Due to the peculiarities in the structure of the female and male figure, their BMI is different. It is also necessary to take into account the age of the person being checked, because the optimal weight will differ for a young and an elderly person.
When analyzing the body mass index (the ratio of weight and height), one should take into account the fact that for men and women it will be different due to the peculiarities in the structure of the female and male figures. Over the years, a fat layer is added that is heavier than muscle tissue. Because of this, a mature person can have an ideal ratio and be overweight at the same time.
Special calculations are used to determine the optimal mass index of children. In a special way, BMI is calculated for athletes. Thanks to training, they have powerful muscles, and their ideal weight will be much higher than that of an ordinary person.
How to calculate BMI using formulas
When calculating the index of weight and height, they mainly use such simple actions: for women, 110 is subtracted from height (cm), and 100 for men. But in this formula, age, constitution of the individual, and other factors are overlooked.
It is quite difficult to calculate the correct indicator on your own, taking into account all the subtleties. For people who want to maintain their weight in order, a calculator was invented - online. 
You just need to write down your data (height, weight) in a certain form and after 2-3 s. the display will show the result. Additionally, mention of the circumference of the hips and wrists may be required.
The results obtained must be compared with the table, and a conclusion should be made about the body weight of the subject.
Calculation of body mass index by different methods
Eat various ways calculating an index by which it is possible to independently determine your suitable weight and determine how many kilograms you need to lose. It is very important to remember that none of the methods will give an accurate idea of the existing body composition, because. every organism has its own characteristics.
Only a highly qualified specialist will help to correctly assess the condition of the patient's physical body. If the available weight is slightly different from the calculated norm, while feeling great, do not panic. Most likely, this is the individual norm.
Brocca's formula
The most recognized and widespread is the formula of the French anthropologist Brock, suitable for people of normal build, who are above 150 cm and below 185 cm.
Having a certain growth, you need to subtract the coefficient:
- up to 165 cm - 100;
- up to 175 cm - 105;
- from 175 and above -110.
In this calculation, it is necessary to take into account the type of physique, and change the result:
- Asthenic (thin bone) - reduce by 10%;
- With normosthenic (medium bone) - subtract 110 from growth;
- Hypersthenic (wide-boned) - increase by 10%.
The optimal weight for women and men is calculated differently depending on the type of addition To determine your type, you need to measure the circumference of your wrist working hand. Women's sizes for all types in order - up to 16, 16-18, 18 and above. Men have such girth values - up to 17, 17-20, more than 20.
Quetelet formula
A mathematician of Belgian origin Quetelet proposed his own method for calculating BMI. The formula is elementary, and consists in the need to divide the weight of the subject by the height (meters) squared.
| Classification based on BMI | BMI | What to do |
| underweight | 19 | recommended to increase weight |
| -great shortage | Under 16 | |
| - medium deficit | 16-17 | |
| -small shortfall | 17-19 | |
| normal weight | 19,5-25,0 | |
| Excess body weight | Over 25 | need to reduce weight |
| 1 stage obesity | 25-30 | |
| stage 2 obesity | 30-35 | strongly recommend weight reduction |
| 3 stage obesity | 35-40 | |
| stage 4 obesity | over 40 | need to lose weight immediately |
These indicators are applicable to representatives of both the stronger and the weaker sex.
This calculation has some corrections. For example, it is not suitable for pregnant women, the elderly and children. The coefficient may vary depending on the complexion or the amount of muscle mass.
If the indicator is above 30 units. it is advisable to take serious measures: visit a qualified specialist, contact a nutritionist and go in for sports. 
Lorentz formula
The weight and height index for women can be calculated using a very simple Lorenz formula, which will help to get a value very similar to the results of other, more painstaking calculations.
To derive the coefficient, you need to know your height in centimeters (P) and carry out the following calculations:
- R-100-(R-150)/2. The resulting number indicates a normal mass, favorable for a person;
- For the abbreviated Lorentz formula, P / 2 -25 is necessary. In other words, subtract 25 from half of our growth.
This technique is relative, and does not allow you to find out the optimal weight with absolute accuracy. Body type is not taken into account here and the age factor is overlooked. Indeed, at different ages, different body weights are considered the norm.
Breitman formula
To derive the weight and height index according to the Breitman formula for women, with a height of 165, it is necessary to subtract 100 from 165. For a universal calculation, you need to multiply the growth by a factor of 0.7 and subtract 50.
Body mass index for women
The mass index of weight and height is easy to calculate for women by applying Brock's formula: we subtract 100 from height in cm. If we subtract 10% from the result, we will get the ideal weight.
Having received too high a value, it can be argued that the subject is at risk and prone to diseases of cardio-vascular system, hypertension, impaired functions of the respiratory system, etc.
The extracted norm can be considered for each lady individually. It is due to age, and is different in young girls and mature women. For a more accurate definition, it is also worth considering the proportion of muscle and adipose tissue.
So, if you use the Quetelet form to calculate the BMI of a girl using average parameters, then with a height of 1.71 and a weight of 64 kg, we get: 1.71 * 1.71 = 2.9241; 64/2.9241=21.89. Normal for the fairer sex is an indicator from 19 to 24, and in this example it is normal.
Body mass index for men
The weight of a man depends on the individual physical form, well-being, and is commensurate with the height and width of the chest. The presence of excess kilograms indicates deviations in the work of many body systems, therefore it is very important to determine your ideal weight and stick to it.
You can calculate BMI for a man with average parameters (height-176, weight-88) using the formula: 88 / (1.76 * 1.76) \u003d 28.4. A value from 19 to 25 is considered a normal coefficient. The coefficient found above indicates extra pounds.
A clearer idea of the distribution of adipose tissue can be defined as follows: divide the waist by the volume of the buttocks. For the stronger sex, the norm is 0.85.
By applying the Nagler formula, a man can independently find his optimal ratio.
Having a height of 152 cm, the body weight should be 45 kg. Adding 0.9 kg to the weight for every next 2.45 cm of height, we derive a number, and if it matches the actual kilograms, then this is regarded as the norm. If there is a large discrepancy, it is advisable to take the necessary measures.
With the help of growth (P) BMI for the stronger sex can also be calculated as follows: P-(100+(P-100)/20)
Body mass index for children
Similar to calculating BMI for adults, you can calculate this indicator for children and identify excess kilograms, or a tendency to obesity. 
BMI = weight in kg / square of height in m.
For example, if we take the average value, when a child with a height of 1.5 m. weighs 45 kg, then we get: 45 / 2.25 \u003d 20. For a girl or boy 13-14 years old, this is considered normal. Children are constantly growing, and this means that this factor must be paid attention to. The table below shows the optimal indices for different ages.
| Child's age | Girl | Boy |
| 0-2 | 13,3-15,4 | 13,4-15,7 |
| 2-3 | 15,3-16 | 15,3-16,5 |
| 4-5 | 13,5-16,5 | 13,8-16,8 |
| 5 | 13-17 | 13-17 |
| 6-8 | 13,5-18 | 13,5-18,5 |
| 9-10 | 14-20 | 14-21 |
| 11 | 14,5-20,5 | 14,5-21,2 |
| 12 | 16-21,5 | 15-22 |
| 13-14 | 16-23 | 16-23 |
| 15-16 | 17-23,5 | 17,5-24 |
Even with the available data, the indicators are not easy to interpret. If in any doubt, it is best to consult a pediatrician. It will help determine the optimal weight and general development child's body, and in case of deviations will be able to give the necessary recommendations.
Body mass index for teenagers
For correct definition The BMI of a teenager needs to be done in the same way as for children, because using adult measurements is not entirely correct. During puberty, it is necessary to carefully monitor the body weight of a teenager. The coefficient is calculated using the percentile. 
To find it, weight must be divided by height squared..
The resulting value does not contain the proportion of commensurate tissue types with growth, because of this there is the possibility of inaccuracies and misinterpretations.
The obtained result must be compared with certain data, due to the age of the teenager, and we will get a comparative value (SV BMI).
In boys and girls, this figure may differ, because the average level of muscle mass in men is higher than in women.
The found result of CV BMI meets the following indicators:
- more than 95 - obesity;
- from 85 to 95 - overweight;
- from 5 to 85 - the norm;
- less than 5 - lack of body weight.
Body mass index during pregnancy
The weight and height index for women during childbearing is calculated using the Quetelet formula. This coefficient is determined by the gestational age, and by comparing it with the permissible norms, you can find out how many kilograms a future mother can gain. To do this, you still need to know the weight of the lady before conception and her height. 
Insufficient weight gain by a pregnant woman can be a reason for abnormalities in the development of the fetus. Excessive addition of kilograms can cause difficulties in independent childbirth.
The norm during pregnancy is the addition of 7 to 16 kg. But in practice, it happens that mothers with extra or missing kilograms have produced healthy babies.
If there is any doubt about the weight future mother can cause Negative consequences for the baby, no need to worry prematurely.
The maximum allowable body weight, taking into account age
The weight and height index is easy to find for women under 40, subtracting 110 from height in centimeters, and for ladies after 40 years, subtract 100cm.
It is obvious that with age, weight increases due to changes in carbohydrate metabolism, and this process is natural. This reduces:
- metabolism;
- changes in energy and physical activity;
- volume of muscle structure;
- metabolic movement;
- hormone activity.
Optimal body weight varies for different ages Many scientists to calculate the coefficient allowable weight for ladies, the standards of Egorov-Levitsky are used. These indicators indicate the maximum allowable weight at a particular age. Exceeding the BMI below indicates excess body weight.
| Height, m | Age, years | ||
| 20-30 | 31-40 | 41-50 | |
| 1,66 | 65,2 | 71,8 | 76,5 |
| 1,68 | 68,5 | 73,7 | 78,2 |
| 1,70 | 69,2 | 75,8 | 79,8 |
| 1,72 | 72,8 | 79,3 | 82,8 |
| 1,74 | 74,3 | 79,0 | 83,7 |
Why you need to know your BMI
Knowing your BMI is necessary for those who care about their health and their figure. Doctors use this factor to select the dose medicines. At home, you can control your weight with it.
The calculation of the indicator will help to identify the presence of abnormalities in the body, and their severity. Based on the data obtained, dieticians can prescribe an appropriate diet and exercise regimen for obese patients.
BMI is a standard way to determine the level of obesity in men and women
Nevertheless, with any weight adjustment, it is not recommended to trust only the obtained indicator. If it does not correspond to the norm, then it is worth doing additional research.
Analysis of BMI results
It is worth emphasizing that the BMI standard changes periodically. For example, in the US at the end of the 20th century, the normal index was 27.8. Then the standards changed, and the figure dropped to 25. This was the reason for the increase in the number of overweight citizens.
According to Israeli scientists, the optimal ratio for men is 25-27. For women, the normal index of weight and height completely coincides with the standard.
BMI has an indicative value and is used primarily by doctors and nutritionists. Having calculated the number yourself, it must be compared with WHO standards in a separate table.
When identifying obesity or underweight, you should not rely with full certainty on the derived index. So, people who have highly developed muscles and do not have extra pounds may have an overestimated figure.
Degrees of obesity by BMI
Having determined your weight and height index using Brock's formula for women, and identifying extra pounds, they classify overweight from optimal using the table:
| Excess,% | Stage of obesity | Actual BMI |
| 20-30 | 1 | 25-30 |
| 31-50 | 2 | 30,1-36 |
| 51-99 | 3 | 36,1-40 |
| Over 100 | 4 | More than 40 |
Obesity levels 1 and 2 are considered as a minor cosmetic defect. It can cause mild discomfort, and cause further weight gain. At the extreme stage of obesity, pathological abnormalities are formed that affect all vital systems of the body.
Obesity can be of the following types:
- stable level for a long period of time;
- progressive- characterized by a rapidly increasing or slow continuous set of kilograms;
- residual- weight can increase significantly after a long period of weight loss.
Disadvantages and limitations in using the BMI method
The interpretation of the BMI values proposed by WHO does not take into account the age and sex of the individual. Evidence from many countries suggests that women's optimal weight index is lower than men's. In addition, it is higher among middle-aged citizens compared to young and old people.
The word “norm” means “averages”, but the statistics say that the “standards” for BMI, according to WHO regulations, do not correspond to the typical normal distribution of BMI indicators among residents.
It may be that the weight and height index, which is optimal for women in one country, will be overestimated for women living in many other countries of the world. For example, in Russia, if you follow the recommendations of the WHO, then most of the population over 30 years of age have extra pounds.
How to normalize body mass index
Excess weight, as well as insufficient, lead to serious disturbances in the functioning of the body. With small deviations from the norm, do not worry.
If the discrepancies are significant, first of all, you should consult a specialist. He will select the optimal diet and prescribe a diet.
- increase the calorie content of portions by increasing the intake of food and more frequent intake using protein products;
- study exercise aimed at adding body weight, excluding exhausting workouts;
- create conditions for healthy and sufficient sleep.
Those who have a non-critical excess of kilograms should adhere to the following rules:
- reduce the amount of food consumed;
- exclude fatty foods from the diet, reduce the intake of eggs, coffee, alcohol;
- diversify your diet with a sufficient amount of vegetables, fruits, low-fat dairy products, cereals, lean meat and fish;
- follow the diet. At night, it is better to drink kefir or eat fruit.
- choose sports activities that promote fat burning;
- breathe as much as possible fresh air and get adequate sleep.
It is advisable to track your weight and height index, which is especially important for women, because its deviations can cause hormonal failure. A lack of body weight leads to a decline in strength, a decrease in immunity. Extra pounds create problems with the cardiovascular system, contribute to loss of activity.
When looking for optimal BMI indicators, you should, first of all, listen to your body. If the numbers indicate deviations, but the state of health is quite comfortable, then you can live a full life without reaching your ideal weight.

Height to Weight Ratio: Windows App Overview:
The problem of weight worries all girls. The thinking of a young lady is so arranged that she can never be satisfied with her weight. It always seems that the weight is either overweight or underweight, and finding such a unique girl who would consider her height and weight ideal is almost impossible. And if weight can still be influenced, then height - alas, no. And in this case, only high-heeled shoes will help. Therefore, today we will focus on existing methods of how to calculate the ideal weight for a girl.
What is the ideal weight for a girl?
If we forget for a while what we are told from TV screens and the pages of glossy magazines, about the “beauty standards” adopted by someone, about the opinions of plastic surgeons and other interested parties, then we can say that the ideal weight for a girl is her natural weight. Let's explain it this way - nature, endowing a person with certain physical data, is guided by its own rules and standards. For some reason, she creates people with different proportions of height and body weight. If the existing “ideal” norms fit all people, then everyone would be born with the same height and weight, and grow according to the plates printed in pediatrics textbooks. But after all, when a child grows, it never occurs to anyone that he needs to be limited in food so that he fits into the tabular data. So why, then, young girls do not admit that a certain body weight was given to them not just like that, but for some purpose? At the very least, they should think about it.
And if you belong to the category of people who believe that the ideal female weight is not a natural weight, but an established norm, then we suggest that you familiarize yourself with various formulas that help calculate the ideal weight for a girl and a woman.
Method one
Everyone is well aware of the following formula, ideal weight = height minus 110. But this formula does not attach importance to such a parameter as a person's age. And as described above, the formula is suitable for women aged 40 to 50 years. If we talk about girls, that is, if the woman's age is from 20 to 30 years, then the formula takes the following form, ideal weight = height minus 110 and minus 10%. And for women over 50, the formula looks like this, ideal weight = height minus 110 and minus 7%. Example: the height of a girl is 165 cm. Then her ideal weight is (165 - 110) × 0.9 = 49.5 kg.
Method two
According to American scientists, the ideal weight for a girl can be calculated as follows: (height minus 150) times 0.75 and add 50.
Example: the height of a girl is 165 cm. The ideal weight is (165 - 150) × 0.75 + 50 \u003d 61.25 kg.
Method three
This formula for calculating the ideal weight is called the Lorenz formula. Ideal weight \u003d (height - 100) - 0.25 * (height - 150). Example: a girl's height is 165 cm. Ideal weight \u003d (165 - 100) - 0.25 * (165 - 150) \u003d 61.25 kg.
Method four
This method of determining the ideal weight is called the Catle index. The index is equal to a person's weight (in kilograms) divided by the square of height (in meters). 
If the calculated index is below 18, then this indicates a low body weight. If in the range from 18 to 25, then the weight is considered normal, and if over 25, then the weight is overweight, the probability of obesity is high.
Example: girl's height is 165 cm, weight is 65 kg. BMI = 65 / (1.65 × 1.65) = 23.87. So the weight is normal.
Also, using this method, you can determine the boundaries of the normal weight for a girl. To determine the lower limit, you need to multiply 18 by the square of height in meters, and for the upper limit, multiply 25 by the square of height in meters.
Example: the height of a girl is 165 cm. The lower limit of body weight = 18 × 1.65 × 1.65 = 49 kg. Upper limit of body weight = 25 × 1.65 × 1.65 = 68 kg.
Method five
To calculate the ideal weight for girls, you need to use the following formula: multiply height by chest volume and divide by 240. Example: girl's height is 165 cm, chest volume is 90 cm. Ideal weight \u003d 165 × 90 / 240 \u003d 61.9 kg.
