There are different formulas for determining the optimal ratio of weight and height. But all of them are very, very conditional, since they do not take into account many factors: age, gender and physiological characteristics of a person. Therefore, excess fat must be assessed not only by the conditional ratios presented in this table, but also by appearance, skin thickness and a number of other factors. With the same height and weight, one person may look plump, while another may look completely normal.

The objective parameter of an ideal body is the percentage of fat and musculoskeletal tissue. For men, the norm is 9 - 15% fat of total body weight, and for women - from 12 to 20%.

Quetelet index

Knowing the Body Mass Index (BMI), you can judge whether you are obese or underweight. The index is calculated for adult men and women from 20 to 65 years old. Results may be false for pregnant and breastfeeding women, athletes, the elderly and adolescents (under 18 years of age). Among the many different methods for calculating ideal weight, the most popular method is the height-weight indicator, body mass index - Quetelet index.

Formula: body weight in kg divided by height in meters squared B/(P*P)

For example: height 170 cm, weight 65 kg. So 65: (1.7 * 1.7) = 22.5

The norm for men is 19-25. For women - 19-24.

The Quetelet index shows quite well the amount of fat in the body, but does not indicate how fat is distributed, in other words, it does not provide a visual or aesthetic picture. But you can test your body for ideality using one more formula.

The distribution of fat throughout the body is determined by the ratio: waist volume (at the level of the navel) divided by the volume of the buttocks.

• Norm for men: 0.85
• For women: 0.65 - 0.85.

Does age affect height-weight ratio?

The answer is clear. Yes, of course it does. It has been proven that the weight of men and women should gradually increase with age - this is a normal physiological process. The kilograms that some people consider “extra” may not actually be so. You can use a formula based on age to determine your optimal weight.

P is height in this case, and B is age in years. Body weight = 50 + 0.75 (P - 150) + (B - 20) : 4

Broca's formula: identifying height-age-weight relationships

One of the most popular methods for calculating ideal weight is Brock's formula. It takes into account the ratio of height, weight, body type and age of a person.

Broca's formula for people under 40 years old is "height (in cm) minus 110", after 40 years - "height (in cm) minus 100".

At the same time, people with an asthenic (thin-boned) body type must subtract 10% from the result, and people with a hypersthenic (broad-boned) body type must add 10% to the result.

How to determine your body type?

Body types are usually divided into THREE types:

• normosthenic,
• hypersthenic,
• asthenic.

In order to find out what your body type is, just measure the circumference of the thinnest place on your wrist with a centimeter. The resulting circumference in centimeters will be the necessary indicator (Soloviev index).

Nagler's formula for height and weight ratio

There is a Nagler formula that allows you to calculate the ideal ratio of weight and height. For 152.4 cm of height there should be 45 kilograms of weight. For every inch (that is, 2.45 cm) over 152.4 cm there should be another 900 grams, plus another 10% of the resulting weight.

John McCallum's formula for girth ratio

One of the best formulas, created by expert methodologist John McCallum. McCallum's formula is based on measuring the circumference of the wrist.

1. 6.5 wrist circumference is equal to chest circumference.

2. 85% of the chest circumference is equal to the hip circumference.

3. To get your waist circumference, you need to take 70% of your chest circumference.

4. 53% of the chest circumference is equal to the hip circumference.

5. For the neck circumference you need to take 37% of the chest circumference.

6. Bicep circumference is about 36% of chest circumference.

7. The girth for the lower leg is slightly less than 34%.

8. The circumference of the forearm should be equal to 29% of the circumference of the chest.

But not everyone’s physical data will exactly correspond to these ratios; the numbers have an average, statistical average value.

A few more options for height and weight ratios

• The physique is considered ideal if the waist circumference is 25 cm less than the hip circumference, and the hip circumference is approximately equal to the chest circumference.
• The waist circumference should be equal to “height in centimeters - 100”. That is, a woman with a height of 172 cm will be proportionally built if her waist circumference is 72 cm, her hip and waist circumference is about 97 cm, that is, if she wears a clothing size of 48.
• If the hip circumference is less than the chest circumference, and the waist circumference is 20 cm less than the hip circumference, then this figure is called an “apple”. If the chest circumference is less than the hip circumference, and the waist circumference is 30 cm or more less than the hip circumference, this is a pear-shaped figure.
• For women and girls of average height - from 165 to 175 cm - this observation turned out to be fair. Their waist circumference in centimeters is approximately equal to their weight in kilograms. One kilogram of weight loss results in a decrease in waist size of one centimeter.

As you can see, there are many ways to calculate the optimal ratio of your height and body weight, depending on a variety of factors. But no matter how you make the calculations, the main thing is that your weight is COMFORTABLE for you. So that you feel easily and freely in your own body, love yourself and enjoy life to the fullest! - without falling into depression because during the calculations you (what if!) discovered an “excess” or “lack” of kilograms. published

At all times, women paid special attention to their appearance, and the leading position here was occupied by the figure or weight of the representative of the fair half of humanity. And if from century to century ideas about the ideal forms of a girl have changed dramatically, medical concepts of ideal weight have generally remained unchanged for several centuries. Excessive fatness, or, conversely, thinness, which were the standards of beauty in different eras, is not in fashion today. And if we talk about the ideal weight for a girl today, then the most important thing here is moderation in everything.

Is there an ideal height and weight for a girl?

Until recently, the recognized standard of beauty was an almost boyish figure, with no room for anything “extra.” Today you can often come across heated debates about the ideal figure and the ideal weight; as a rule, these are two opposing camps, the participants of which are ready to debate for a long time about what a modern representative of the fairer sex should look like, what is the ideal weight for a girl. Some argue that it is necessary to “hang out” in the gym all day long and carefully count all the calories that enter the body during the day. Others are trying to prove the opposite point of view is correct - that you shouldn’t torture your body with workouts and strict diets, you can calmly eat whatever you want and not abuse your body on the treadmill. As always, the truth is somewhere in the middle; the ideal weight for a woman is her natural weight. And in order to find out the treasured figure, it is important to take into account many other factors, and not just the value touched by the scale arrow. It is necessary to take into account height, age, body type, as well as body volumes and proportions.

Today, there is more than one formula by which women in different countries calculate their ideal weight. But the calculations obtained using these formulas do not mean that this ideal weight for your height for girls should be the only correct one. The information that you will see in the table of ideal weight for girls is more of an informational and advisory nature. Only a personal nutritionist can provide the most complete information, who will know not only your obvious data (height, volume, age, proportions), but also individual characteristics and diseases. After all, a lot depends on them too.

Ideal weight table for girls

The most famous way to calculate ideal weight is the formula of the French anthropologist Broca, which is relevant for people above 155 and below 185 centimeters. This formula for calculating ideal weight and height has been used since the 19th century. You need to find out your height, and then subtract 100 if your height is less than 165 centimeters. If a girl’s height is up to 175 centimeters, then 105 must be subtracted from her height. If a girl is lucky enough to be born tall, and her height exceeds 175 centimeters, 110 must be subtracted from it.

However, this is not the end of the calculations of the ideal weight for your height for a girl. When calculating, it is necessary to take into account your body type. It is calculated by the circumference of the wrist.

If the wrist circumference is less than 15 centimeters, this is an asthenic girl. A hand circumference of 15 to 18 centimeters is usually characteristic of normosthenics. The wrist circumference is from 18 centimeters for hypersthenics. For asthenics, the number obtained from “subtracting” growth should be reduced by 10%. This will be the “ideal” weight. Hypersthenics need to add 10%. And for normosthenics, additional calculations are not required.

To make it clearer, let's look at specific examples. The ideal weight for a height of 165 for a normosthenic girl can be found out by simply subtracting 100 from 165 - in the end we get 65 kilograms.

We can calculate the ideal weight for an asthenic girl who is 170 tall if we subtract 105 from 170 and minus 10%. We get 170-105=65. And another “minus 10%” = 58.5 kg.

We find out the ideal weight at 160 for a hypersthenic girl by making the following calculations: 160-100 = 60 and minus 10%. We get 54 kilograms.

It is important to remember that these calculations do not take into account additional factors: age, volume, body mass index. The last point should also be taken into account, since an athletic girl with trained muscles may weigh more than a woman who does not play sports. This happens because fat is lighter than muscle, and in this case, a trained girl with a lot of weight will look more attractive than a lighter sybarite who is not into sports.

To make the information received better remembered and perceived, we present a table of weight and height correspondence.

However, there is an exception to the table. If the girl’s height does not exceed 159 cm, her weight should be 15% less than the given value. And if the girl is under 20 years old, you need to subtract another 3-5 kilograms from the obtained value.

Ideal weight for your age for girls

A person's weight increases with age, and this is considered normal. Of course, its increase should be “within what is permitted” and not be too sharp, strong and critical for a person’s appearance and lifestyle. A woman may feel that her weight is higher than normal, but at the same time it will be within the normal range for her age. To calculate ideal weight based on age, use the following formula: 50 + 0.75 (P-150) + (B-20) /4

In this formula, P is a person’s height, and B is his age. For example, for a girl 27 years old and 170 cm tall, judging by this formula, the ideal weight would be 66.75 kg. 50 + 0.75 (20) + (7) /4 = 66.75

Also, what is the ideal weight for a girl with a height of 150, 160, 165, 170 cm and above, the corresponding table, which is also focused on the person’s age, will help you find out.

Let's imagine a picture: we wake up in the morning, take a shower, and have breakfast. And when the time comes to put on your favorite jeans, we realize with horror that we cannot button them - our stomach is in the way. We crawl under the sofa, find dusty bathroom scales, stand on them and... A familiar story, right?

Whatever number is displayed on the scale, frustration and depression are achieved - you can’t wear jeans now. What to do? You can just score. Throw your pants in the trash or push them into the farthest corner of the chest of drawers - let them lie there until better times. Or you can go the other way - lose a couple of extra pounds - maybe the trousers will fit.

The second option is more difficult - you need to do something, spend time, make efforts. However, we clench our will and decide to lose weight. But before starting, one more question arises - what to strive for, how many kilograms you need to lose in order to feel completely good: so that your pants fit, and you can breathe easier, and so that you won’t be ashamed to go to the beach in the summer. We are thinking and trying to figure out how to calculate our ideal weight?

It turns out that ideal (correct) weight is an abstract concept, and it means the average value obtained on the basis of a set of given physiological parameters of a person, such as height, age, gender characteristics, and body features. But the state of health, level of physical activity, percentage of fat mass in relation to muscle mass and other individual indicators of an individual person are not taken into account here.

This means that it will not be possible to find the exact value of your weight using known formulas. However, we will get an approximate guideline that you can rely on when losing or gaining body weight.

The most well-known types of weight calculation using formulas:

• Calculation of weight by height
• Calculation of weight by age and height
• Weight calculation by BMI (body mass index)

Calculate weight by height

A simple method better known as Brocca's formula. A simplified version looks like this:

• For women: Ideal weight = Height (cm) - 110
• For men: Ideal weight = Height (cm) - 100

Example: the normal weight of a man with a height of 180 cm is 80 kg, and a woman with a height of 170 cm is 60 kg

The modern version of the same formula looks a little different, but is considered more accurate:

• For women: Ideal weight = (Height (cm) - 110)*1.15
• For men: Ideal weight = (Height (cm) - 100)*1.15

Example: the normal weight of a man with a height of 180 cm is 92 kg, and a woman with a height of 170 cm is 69 kg

Calculate weight by age and height

The following weight determination method is not a calculation formula. This is a ready-made table with which you can calculate the correct weight by age. And if the previous version gives an approximate norm of human body weight, then the Egorov-Levitsky table, as it is also called, displays the maximum permissible weight value, exceeding which is considered unacceptable for a given height and age group.

All you need is to know your height, age and current weight. Look for the intersection of these parameters in the table and understand how far you are from the maximum permissible value. If the number in the table is higher than your existing weight, good, if lower, there is reason to think about the gym and dietary restrictions.

Example: A woman with a height of 170 cm, 35 years old, weight 75 kg. The intersection of the table shows a maximum weight value of 75.8. The woman is one step away from this value. Therefore, close control of body weight is necessary, otherwise it is possible to go beyond the permissible limits.

Calculate weight using BMI (Quetelet body mass index)

table for calculating optimal weight using Quetelet body mass index

Using the Body Mass Index, you can find out in what predetermined range a person’s current weight is: deficit, normal or obese (all BMI values ​​are shown in the table).

BMI is calculated using a formula that takes into account the initial values ​​of height in meters and weight in kilograms. The formula looks like this: KMT = weight in kilograms: (height in meters * height in meters).

Example: a man with a height of 185 cm (1.85 m) and a weight of 88 kg will have a BMI = 88: (1.85 * 1.85) = 27.7. We look for the value in the table and understand that the index is in the range of Overweight (pre-obesity).

An important point: calculating the correct weight according to BMI does not take into account gender and age-related changes in the body.

Conclusion

It is important to remember, no matter which method of calculating the correct weight you choose, the result of the calculations should not be taken as the absolute truth. All figures will be approximate and indicative. And these calculations still won’t fit your jeans. So, put dumbbells in your hands, put your feet in sneakers, put a lock on the refrigerator and go ahead - towards the result.

Now it has become fashionable to be healthy, so people began to monitor their weight in relation to height and age, trying to adjust it to the ideal one.

At your service is an online BMI (ideal body weight) calculator for women and men, for boys and girls, as well as for teenage children.

Parents who want to raise healthy children can also use the calculation of the weight of a child - from an infant and older - from the ratio of his weight to gender, age and body length.

The calculation of body mass index for women, men and children is based on World Health Organization (WHO) standards, taking into account age, weight, gender and body type.

Any normal parent - mom and dad - want to raise a child happy and healthy. Proper care of a baby includes knowledge of his weight, body length, general development - this is periodically checked at an appointment with a pediatrician.

Calculate the BMI of adolescent children (girls and boys) under 19 years of age

Teenage boys and girls, teenage boys and girls are the most emotionally and psychologically vulnerable link in society. Due to puberty, a “hormonal surge” and personal immaturity, as well as due to the advanced development of the body over the psyche and maximalist thinking, teenage children can be very worried about their appearance, especially with regard to their figure, weight and height.

If you are striving for appearance fashion, then your expectations for BMI results may not be met. health fashion.

Body mass index calculator for adult women and men based on age (20 to 69 years) and body type

Using this online BMI calculator, you can easily calculate the body mass index for women and men, taking into account age from 20 years and above, and body type (asthenic, normosthenic and hypersthenic).

Briefly about innate body types. Asthenic (Ectomorph) - thin body, narrow and elongated bones of the limbs, thin adipose tissue; Normosthenic (athlete, mesomorph) - proportional body, normally developed muscles; Hypersthenic (Picnic, Endomorph) - wide bones, short stature, developed muscles... sometimes a tendency to be overweight.

Attention! The results of determining the ideal weight may be distorted in the case of pregnancy, breastfeeding, professional sports (not physical education) and diseases associated with neoplasms (tumors, hernias... etc.).

BMI (ideal body weight) tables for women, men, children and adolescents

In the modern world, determining your body mass index, calculating your ideal weight the old fashioned way, such as Height minus 100, is no longer suitable. Nowadays, special BMI tables are used that show medical weight standards in relation to height, physique, and taking into account age and gender.

The formula for calculating BMI according to Kegle: Body weight (kg) divided by Height (m) squared.

For example: a young woman aged 25 with a weight of 50 kg and a height of 1.62 m calculates an index of 50/(1.62*1.62)=19.05 - a normal body mass index, but close to an underestimation (less than 19 - deficiency weight).


If you have problems with your ideal body weight: problems with overeating, anorexia nervosa or bulimia, or you don’t know how to convince yourself to become slim and healthy -

To “sculpt” the ideal figure will require a significant amount of time and effort. However, before you begin this difficult task, go to the mirror and look at yourself critically, but with love. You can take a centimeter and measure all your circumferences, but don’t draw any gloomy conclusions if you don’t get 90-60-90.

Most likely, it really won’t work out, but there is no tragedy in it. First of all, a lot can be fixed. Secondly, many things may not need to be corrected.

Constitution type

For example, anthropologists distinguish three main types of constitution (not to mention numerous transitional and intermediate options). These three types are called: normosthenic, hypersthenic and asthenic.

A person with a hypersthenic constitution is most often of average or below average height, broad-boned, with relatively short arms and legs and a wide chest. Asthenic - tall, long-legged, with a narrow chest, everything seems to be directed upward. Normosthenic means “normal”: average height and everything else too.

You can quite accurately determine your constitutional type by the so-called intercostal angle, which is formed by the lowest costal arches. Stand in front of a mirror with your stomach in and your chest out, and see what your intercostal angle is (you can even take a large protractor and measure).

If it is approximately 90 degrees, then you are normosthenic. If this angle is acute, less than 90, you are asthenic, and if it is obtuse, you are hypersthenic. In the latter case, in particular, successful getting rid of excess weight can lead to a not very successful result: thinness will not decorate a hypersthenic person, and some “extra” weight, on the contrary, will round out the somewhat square outlines of the figure.

Ideal weight is not a number on the scale, but an integral and important component of your life.

Ideal weight

Your weight is ideal if:

• It does not cause health problems (or potential risks);
• It does not limit you in your daily life, desires and needs;
• You are satisfied with your body the way it is, and at the same time you do not feel embarrassed;
• You like your body and don't compare yourself to other people (or actors, singers, athletes, etc.).

There are various indicators and formulas that can determine the approximate weight range in which you may begin to experience health problems, as well as the weight to which you should strive to minimize or completely eliminate these problems.

Methods for determining excess weight

1. Determining excess weight using scales

The simplest (and most approximate): height (in centimeters) minus 110. The resulting number (in kilograms) is the ideal weight. However, this does not mean that “everything else” is superfluous.

There is the simplest and most accurate way to determine whether you are overweight: you just need to measure the crease on your stomach. For women, the permissible norm is 2-4 cm, but for men it is slightly less - 1 - 2 cm. Experts say that 5 cm or more is obesity. True, unfortunately, in this case we will not see the exact result of how much we need to lose. This is just a kind of hint that it’s time to start exercising and going on a diet.

3. BMI - Body Mass Index

The so-called body mass index (BMI) has received general recognition. His calculation: divide your weight in kilograms by your height in meters squared. Example: BMI = 68kg: (1.72m x 1.72m) = 23. This formula is good because it works for both “little ones” and “giants”.

The following BMI values ​​are distinguished:

less than 15- acute weight deficiency;
from 15 to 18.5- weight deficiency;
from 18.5 to 24 - normal weight;
from 25 to 29- overweight;
from 30 – 40– obesity;
more than 40- severe obesity.

5. Scales that determine the percentage of body fat

But BMI does not indicate the distribution of kilograms on the body. Body type is important. With the same height and weight, one person will be slim and strong, the other - plump and loose. The ratio of muscles and fat is important, what percentage of the total body weight is fat, how much is muscle and bones, how much is water. The normal proportion of body fat for men is 12–18%, for women – 18–25%.

Recently, devices have appeared to determine the percentage of body fat. In the process of bioelectrical analysis, a weak, absolutely safe electric current is passed through the body. The principle of analysis is based on the fact that an electrical impulse travels more easily through muscle and water than through fat. Now there are scales that include this technology; you can use them to regularly and more or less accurately measure at home not only your weight, but also your fat percentage.

6. Formula for determining realistically achievable weight

The formula is applicable for cases when a person begins to lose weight from a fairly large weight.

The calculation is carried out in two stages:

1. First, determine your weight as if you had a normal metabolism:

(45 kg) + (1 kg for each centimeter of height over 150 cm) + (0.5 kg for each year over the age of 25, but not more than 7 kg).

2. Then correction is made for slow metabolism:

Add from 4.5 to 7 kg;

Add another 4 to 7 kg (with an initial weight of about 90 kg);

A few more kilograms are added (with the initial weight greatly exceeding 100 kg).

An example for a fifty-year-old lady with a height of 158 cm and currently weighing 90 kg:

45 kg + 1 kg (158 cm - 150 cm) + 7 kg +7 kg + 7 kg = 74 kg.

If our lady manages to bring herself up to 60 kg, then she is guaranteed all sorts of health troubles and an inevitable quick return to her original weight, plus a certain number of cheerful kilograms.

How does body weight affect health?

What does the number on the scale actually mean? How does it relate to all the reasons why you want to lose weight? Perhaps you want to look more attractive, improve your health, “fit into” your favorite jeans or put on a beautiful dress that has been hanging in your closet for many years, improve your physical shape, return to youth, or are you simply more comfortable living with fewer kilograms? The number on the scale is not what determines your success or failure. There are so many ways to measure progress and success other than constantly watching the scale.

There is only one reason to talk about a “normal” or “ideal” weight and that reason is your health.

Which can subsequently lead to serious illness or even death. Although your specific weight may not be the cause of any diseases, it is absolutely known that people whose weight is more or less than the “norm” are much more susceptible to various health problems.
