How to calculate how much weight should be. Online calculator for calculating the ideal weight using advanced formulas, taking into account age and physique
At the moment, there are several different formulas that allow you to calculate weight by height and age. But such tables are conditional, since many different factors influence the determination of the ratio of weight and height.
For example, with the same weight and height, one person may look normal, while the other is overweight.
Therefore, excess fat in the body is estimated not only by the above formulas, but also by the thickness of the skin folds and simply by appearance.
In fact, the concept of ideal weight is rather relative, because an indicator of an impeccable physique is not only weight, and there are no single immutable rules of beauty.
The most accurate weighing result will help determine the electronic floor scales. If you have not yet acquired this necessary attribute for weighing or want to replace your scales with more modern and accurate ones, follow this link. You will find not only a huge range of floor scales, but you will also be able to choose the most attractive price for yourself.
For a long time, Brock's weight formula was popular, which helped to calculate the estimated weight-height ratio according to the following system: Height in centimeters minus 100 is equal to ideal weight. However, recently these indicators have been revised and it is believed that this formula is more suitable for determining the weight by age of women 40-50 years old.
Women 20-30 years old should weigh 10-12% less than this indicator, and after the age of 50 years, the weight increases by 5-7%.
This is the easiest way to find out your weight by height and age. Today, other formulas and tables that take into account physique are more often used.
To calculate the best indicator of body fat ratio, you need to calculate the percentage of fat and musculoskeletal tissue. For men, 9 - 15% of body fat is considered the norm, for women, the norm is 12 - 20%.
One of the popular ways to determine the height-weight indicator is the Quetelet index or body mass index (BMI). This index helps to assess how underweight or obese, it is a good indicator of the amount of fat in the body, but does not indicate how this fat is distributed in the body.
The Quetelet Body Mass Index may not be accurate for teenagers, the elderly, pregnant and lactating women, and athletes. Most often, this index is used for adult men and women from 20 to 65 years.
Formula: body weight in kg divided by height in meters squared B / (P * P)
For example: height 180 cm, weight 75 kg. So 75: (1.8 * 1.8) = 23.1
At the same time, the normal figure for men is 19-25, for women - 19-24. Scores from 25 to 29.9 indicate overweight, 30 to 39.9 indicate obesity with a moderate risk of complications (II), and a score above 40 indicates obesity with a high risk of complications (Grade III).
Consider another formula to help check the distribution of body fat:
The waist circumference at the level of the navel should be divided by the circumference of the buttocks.
For example: waist 70 cm, hips 105. So 70: 105 = 0.66
The norm for men is 0.85
For women - 0.65 - 0.85.
Weight by height and age
Another method to calculate weight by height is based on the interdependence of body weight and body type. The physique differs in three main types: aesthetic (thin-boned), normosthetic (normo-boned) and hypersthetic (broad-boned).
To determine your body type, you need to measure the circumference of the wrist of the working hand: for normosthenics it is 16-18.56 cm, for anastenics it is less than 16 cm, and for hypersthenics it is more than 18.5 cm.
thin-boned the type differs in that the longitudinal dimensions of the body predominate over the transverse ones. Women of this physique have thin bones, weak muscles and long limbs, they are usually energetic and not disposed to overweight. People of this type are also called ectomorphs.
Normoosseous physique implies the proportionality of the main dimensions of the body, which makes the figure beautiful.
broad-boned the figure type is distinguished by a significantly larger transverse body size than that of normosthenics. Women of this type have heavy bones, chest, shoulders and wide hips, they tend to be overweight.
To calculate your normal weight by height in grams, you need to multiply your height in centimeters by the weight-to-height coefficient, which corresponds to your age and body type. The recommended weight-to-height ratio (g/cm) is shown in this table.
In addition, age affects the determination of the ratio of height and weight. It has already been proven that with age, the mass of men and women should gradually increase and there is nothing to worry about. “Extra” kilograms may not be such - this is a normal physiological process.
The formula for calculating weight by height and age: Body weight \u003d 50 + 0.75 (P - 150) + (B - 20): 4
In this case, P is height and B is age in years.
Weight, height, age - table for men
In this table, the second and third columns indicate men and women aged 20-29 years, the fourth and fifth - 30-39 years, then 40-49, 50-59, 60-69 years, respectively.
It seems that discussions among men about how much a woman should weigh will never subside. Someone likes seductive plump women, someone prefers more elegant women. Only in one thing men of all countries are unanimous - the most attractive are well-groomed ladies, confident in their attractiveness.
And what does official medicine tell us about this? Body weight is an indicator that determines not only the appearance of a woman, but also her physical and mental health, and most importantly, the quality of life. Changes in weight should be treated very carefully. Rapid weight loss, as well as weight gain, while maintaining the same diet and physical activity, can be signs of various diseases. Therefore, regular weighing once a week should be the norm for people who want a healthy and happy life.
What is the healthiest weight? For the last hundred years, normal weight has been calculated according to the formula of Paul Brock, a famous French surgeon: height in centimeters minus 100. However, modern nutritionists believe that this formula is outdated and can only be used with amendments. For example, to calculate the ideal weight of a woman, you need to multiply the figure obtained when calculating the normal weight using the Brock formula by a factor of 0.85. For men, this coefficient is slightly higher - 0.9. But these indicators do not take into account the age of the person.
How much a woman should weigh at different ages can be calculated using the formula developed by the National Institute of Nutrition in Bucharest: 
(50 + 0.75 * (height in centimeters - 150) + (age - 20) / 4) * 0.9
For example, you are a woman 40 years old and your height is 164 cm. We substitute your data into the formula: (50 + 0.75 * (164-150) + (40-20) / 4) * 0.9 = 58.95 kg.
Thus, your ideal weight is 58.95 kg.
How much a man should weigh can be calculated using the formula: 
50 + 0.75 * (height in centimeters - 150) + (age - 20) / 4
But these figures are not entirely accurate, because they do not take into account the type of physique, and it is different for all people. So, for owners of thin bones and large-boned people, the body weight to which they should strive is not the same.
If you are not a fan of counting, you can use the table below. It takes into account body type. So, if you are the owner of an asthenic physique, your ideal weight is in the lower part of the range, if the normosthenic is in the middle, the hypersthenic is at the end.
To get even more accurate numbers, you need to take into account factors such as the amount of muscle mass, bone density and the amount of fat in the body. Therefore, it is possible to independently determine how many kilograms you need to lose weight or get better only approximately. Experts say that for optimal health, the amount of fat in the female body should not exceed 30% of the total body weight. The fat accumulated around the abdomen is especially dangerous. If its amount exceeds the norm, it can lead to the development of type 2 diabetes, cardiovascular disease and hypertension. To find out if you are at risk, you need to measure your waist. For women, the waist should not exceed 88.9 cm.
To "blind" the ideal figure, it will take a significant amount of time and effort. However, before embarking on 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, just don't draw any gloomy conclusions if you don't get 90-60-90.
Most likely, it really will not work out, but there is no tragedy in this. First, there are many things that can be fixed. Secondly, a lot of things may not need to be corrected.
Type of constitution
For example, anthropologists distinguish three main types of constitution (not to mention numerous transitional and intermediate variants). These three types are called: normosthenic, hypersthenic and asthenic.
A person with a hypersthenic constitution, most often of average or below average height, broad-boned, with relatively short arms and legs and a wide chest. Asthenik is tall, long-legged, with a narrow chest, as if directed upwards. Normostenik means “normal”: growth is average 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 sharp, less than 90 - you are asthenic, and if obtuse - hypersthenic. In the latter case, in particular, successful weight loss can lead to a not very successful result: thinness will not adorn the hypersthenic, 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 important component of your life.
Ideal weight
Your weight is ideal if:
- It does not cause health problems (or potential risks);
- It does not restrict you in your daily life, desires and needs;
- You are satisfied with your body as it is, and at the same time you do not feel embarrassed;
- You like your body and don't compare yourself to the people around you (or actors, singers, athletes, etc.).
There are various indicators and formulas that can determine the approximate weight range in which you may begin to develop health problems, as well as the weight you need to strive for in order to minimize or completely eliminate these problems.
Methods for determining excess weight
1. Determination of 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 easiest and most accurate way to determine if you are overweight: just measure the crease on your stomach. For women, the allowable norm is 2-4 cm, but for men it is slightly less - 1 - 2 cm. Experts say that from 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 sit down at the simulators and on a diet.
3. BMI - body mass index (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 \u003d 68kg: (1.72m x 1.72m) \u003d 23. This formula is good because it works for both “kids” and “giants”.
The following BMI values are distinguished:
less than 15- acute weight loss;
from 15 to 18.5- weight deficit;
from 18.5 to 24 - normal weight;
from 25 to 29- overweight;
from 30 - 40- obesity;
over 40- severe obesity.

5. Scales that determine the percentage of body fat
But BMI does not speak about the distribution of kilograms on the body. Physique matters. With the same height and weight, one person will be slim and strong, the other full and loose. The ratio of muscle and fat is important, how many percent of the total body weight is fat mass, how much is muscle and bone, how much is water. The normal proportion of fat in the body of men is 12-18%, 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 passes more easily through muscles and water than through fat. Now scales have appeared that include this technology, you can use them to regularly and more or less accurately measure at home not only your weight, but also the percentage of fat.
6. The formula for determining the realistically achievable weight
The formula is applicable for cases when a person begins to lose weight with a fairly large weight.
The calculation is carried out in two stages:
1. First determine your weight, as if you were the owner of 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 carry out a correction for a slow exchange:
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, weighing 90 kg today:
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 provided with 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 really 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 your youth, or are you just 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 besides constantly monitoring the scale.
There is only one reason to talk about "normal" or "ideal" weight and that reason is your health.
Which can later 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 above or below the “normal” are much more susceptible to various health problems.

website found 5 ways to calculate the optimal weight used by fitness professionals.
Method 1. Quetelet index
If you know the body mass index, you can judge obesity or underweight. The index is calculated for adult men and women from 20 to 65 years old. The results may be false for pregnant and lactating women, athletes, the elderly and adolescents (under 18).
The resulting number will be your index. The norm for men is 19-25. For women - 19-24.
Method 2. Volumes
The Quetelet index is a good indicator of the amount of fat in the body, but does not indicate how fat is distributed, in other words, it does not give a visual picture. But you can check your body for ideality using another formula.
The distribution of fat throughout the body is determined by the ratio: waist circumference (at the level of the navel) divided by the volume of the buttocks. The norm for men is 0.85; for women - 0.65 - 0.85.
Method 3. Taking into account age
It has been proven that the weight of a man and a woman should gradually increase with age - this is a normal physiological process. Kilograms, which some people consider "superfluous", in fact, they may not be. You can use the formula to determine the optimal weight depending on age.
P - in this case, height, and B - age in years. Body weight \u003d 50 + 0.75 (P - 150) + (B - 20): 4
Method 4. Brock's formula
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.
Brock's formula for people under 40 years old: 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 should subtract 10% from the result, and people with a hypersthenic (broad-boned) body type should add 10% to the result.
How to determine your body type? It is enough to measure the circumference of the thinnest place on the wrist with a centimeter.
Method 5. Nagler formula
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 kg of weight. For every inch (that is, 2.54 cm) over 152.4 cm, there should be another 900 g. Plus another 10% of the resulting weight.
Method 6. Formula John McCallum
One of the best formulas was created by expert methodologist John McCallum. Its formula is based on measuring the girth of the wrist.
- The circumference of the wrist multiplied by 6.5 is equal to the circumference of the chest.
- 85% of the chest circumference is equal to the circumference of the hips.
- To get the waist circumference, you need to take 70% of the chest circumference.
- 53% of the chest circumference is equal to the thigh circumference.
- For the neck circumference, you need to take 37% of the chest circumference.
- The circumference of the biceps is about 36% of the circumference of the chest.
- The girth for the lower leg is slightly less than 34%.
- The circumference of the forearm should be equal to 29% of the circumference of the chest.
But not all physical data will exactly correspond to these ratios, the numbers have an average, average value.
A few more options for the ratio of height and weight:
- The physique is considered ideal if the waist circumference is 25 cm less than the circumference of the hips, and the circumference of the hips is approximately equal to the circumference of the chest.
- The waist circumference should be equal to: height in centimeters - 100. That is, a woman with a height of 172 cm will be proportionately folded if the waist circumference is 72 cm, the hips and chest circumference is about 97 cm, that is, if she wears clothing size 48.
- If the circumference of the hips is less than the circumference of the chest, and the circumference of the waist is less than the circumference of the hips by 20 cm, then such a 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 gives a decrease in the waist by one centimeter.
The ideal male body has always attracted female attention, as if broadcasting information about the strength and success of its owner to the world. Excess weight, as well as its lack, has always been a reason for dissatisfaction with oneself and "corrective" diets, and this problem does not bypass even celebrities. However, it often happens that problems with weight turn out to be far-fetched - a man compares himself with a certain model and strives to change at all costs and become the same, regardless of his natural data. But how do you know what height should be and how much a man should weigh in order for his physique to be considered normal? For this, scientists have created special formulas and calculators that allow you to calculate the ideal ratio of figure parameters, as well as tables that show how much a man should weigh with a certain body composition.
For a more correct assessment of the ratio of height and weight, 3 types of addition were distinguished:
- Hypersthenic - such men have a short neck, arms, legs and broad shoulders. The figure has a strong, squat, stocky appearance. The metabolism is slow.
- Normosthenic - characterized by a proportional, normal build, as well as a moderate metabolism.
- Asthenic - such people have long limbs, neck, narrow shoulders and a fast metabolism. These are “thin-boned” men, dry, sinewy, they usually have little fat deposits, and the bones are light. It is these men who are most likely to be thin.
There are two ways to determine which type you are:
- Grab the wrist of the other hand with the thumb and forefinger of one hand in the place of the largest protrusion of the bone: if the girth turned out to be easy, you are an asthenic, if with difficulty, you are a normostenic, if the girth did not happen at all, you are a hypersthenic.
- Measure the circumference of the wrist with a measuring tape: if the distance is less than 17 cm, you belong to asthenics, 17-20 cm - you are normosthenic, more than 20 cm - hypersthenic.
Table 1. The ratio of height and weight of men
To determine the normal weight for a man, it is necessary to take into account not only height, but body type.
This table shows the normal ratio of male figure parameters. For example, if the growth of a hypersthenic is 170 cm, then it will weigh from 65 to 73 kg, with an asthenic 180 cm, it will be within 66-70 kg.
How does age affect
Scientists have found that the ratio of height to weight is also influenced by age. It is believed that the older a man is, the more his body weight indicator increases, and this is normal.
Age affects metabolism and its speed, which cannot but affect the ratio of weight to height. Table 2 shows how much a man normally weighs, depending on his height and age.
Table 2. The ratio of height and weight of men, taking into account their age
| Height, cm | Age, years | ||||
| 20-29 | 30-39 | 40-49 | 50-59 | 60-69 | |
| 150 | 51,3 | 56,7 | 58,1 | 58 | 57,3 |
| 152 | 53,1 | 58,7 | 61,5 | 61 | 60,3 |
| 154 | 55,3 | 61,6 | 64,5 | 63.8 | 61,9 |
| 156 | 58,5 | 64,4 | 67,3 | 65,8 | 63,7 |
| 158 | 61,2 | 67,3 | 70,4 | 68 | 67 |
| 160 | 62,9 | 69,4 | 72,3 | 70,1 | 68,2 |
| 162 | 64,6 | 70 | 74,4 | 72,7 | 69,1 |
| 164 | 67,3 | 73,9 | 77,2 | 75,6 | 72,2 |
| 166 | 68,8 | 74,5 | 78 | 76,3 | 74,3 |
| 168 | 70,8 | 76,2 | 79,6 | 79,5 | 76 |
| 170 | 72,7 | 77,7 | 81 | 79,9 | 76,9 |
| 172 | 74,1 | 79,3 | 82,8 | 81,1 | 78,3 |
| 174 | 77,5 | 80,8 | 84,4 | 82,5 | 79,3 |
| 176 | 80,8 | 83,3 | 86 | 84,1 | 81,9 |
| 178 | 83 | 85,6 | 88 | 86,5 | 82,8 |
| 180 | 85,1 | 88 | 89,9 | 87,5 | 84,4 |
| 182 | 87,2 | 90,6 | 91,4 | 89,5 | 85,4 |
| 184 | 89,1 | 92 | 92,9 | 91,6 | 88 |
| 186 | 93,1 | 95 | 96,6 | 92,8 | 89 |
| 188 | 95,8 | 97 | 98 | 95 | 91.5 |
| 190 | 97,1 | 99,5 | 100,7 | 99,4 | 94,8 |
Thus, the weight of a guy of 25 years old with a height of 172 cm will normally be about 74.1 kg, at 45 years old with a height of 172 cm - about 82.8 kg. If the height of a guy of 25 years is 180 cm, he will normally weigh about 85 kg, if the height is 182 cm, - 87 kg.
Calculation methods
Calculating the correct ratio of the parameters of a figure is a convenient way to control its state. This task is especially urgent and acute for celebrities, and this is quite understandable: their appearance is a calling card and a working tool. Moreover, diets and training complexes of celebrities are most often repelled precisely from the indicators and numbers that are indicated in the tables below.
Brock's formula
It should be understood that all currently available calculations of body weight norms are not absolute medical indicators and should always be considered individually.
- Its first variant takes into account the type of addition: 110 is subtracted from the height if the man is under 40 years old, or 100 if he is older. People of the asthenic type reduce the resulting figure by 10%, and those of the hypersthenic type increase it by the same number.
- According to the second version of the formula, 100 (with growth up to 165 cm), 105 (166-175 cm) or 110 (above 175 cm) are subtracted from the height. The results obtained will be true for people aged 40-50 years. Those who are 20-30 years old should reduce this figure by 10-12%, and those who are over 50 years old should increase it by 5-7%.
Calculation of parameters and calculator
In order to accurately determine the correct ratio of indicators, you can use a special online calculator. The calculator will allow you to determine the body mass index, ideal Brock weight, body type and the number of calories needed:
- The body mass index calculator calculates using the Quetelet formula. A normal indicator for a male is a figure from 19 to 25.
- A calculator using Brock's formula will help you most accurately calculate the desired ratio. To do this, he takes into account the indicators of the figure and age.
- Body type, or the so-called Solovyov index, will help determine a calculator that takes into account the girth of the wrist in cm.
- A calculator that takes into account the parameters of addition and the level of physical activity of a man will help you calculate the daily daily need for calories. To this end, he uses one of two formulas - Mifflin-St. Geor or Harris-Benedict.
It is worth remembering that calculators and tables for determining the correct ratio of figure parameters are, first of all, only a convenient guide. For this reason, it is necessary to be attentive to the individual characteristics of your body and focus mainly on your well-being, because a beautiful body is inextricably linked with good and good health.
