How to calculate your ideal weight? My result is underweight, but I want to lose more weight. Ideal weight formula for height and age
Do I need to lose weight? Before making such a decision, calculate your ideal weight, the value of which, among other things, depends on age, gender, body type, level of physical activity, profession, water balance, etc.
Before you begin to reduce excess body weight, you need to answer yourself one simple but very important question: “Do I need to lose weight at all?” Often, the excessive pursuit of the ideal figure ends with health problems and mental breakdowns. Remember that the ideal weight is the one you feel most comfortable with. If you wake up in the morning and feel healthy and happy, if you look at your own reflection in the mirror, and you like it, if you are happy, efficient, positive, self-confident - then is there any point in changing something? What for? To meet the standards that the media imposes on us?
If you are serious about the problem of normalization of weight and the improvement of health associated with this, then you should approach this task wisely, having previously obtained the necessary knowledge.
So, the body mass index (BMI), invented by the Belgian sociologist and statistician Adolphe Quetelet, is recognized throughout the world as the simplest and most adequate indicator that allows you to quickly assess body weight. BMI is recommended by WHO as the main criterion for assessing nutritional status, especially when conducting large-scale screenings.
Body mass index (BMI) - a value that allows you to assess the correspondence of body weight to a person's height:
BMI (kg / m 2) \u003d Body weight (kg) / Body height (m 2)
But, like all simple and affordable methods, the calculation of BMI has its drawbacks. It should be borne in mind that excessive or insufficient muscle development can affect the accuracy of determining BMI.
How to correctly evaluate the result, taking into account age, gender and physical condition? Below are the answers to the 4 most common questions about ideal weight.
4 most common questions about ideal weight
1. Does the value of the ideal weight depend on age?
Yes it depends. Over the years, the intensity of metabolic processes in the body naturally decreases (by 0.5% per year). Therefore, it is obvious: in order to maintain your ideal weight with age, you must either reduce the calorie content of the daily diet every year, or increase physical activity. Failure to follow this simple rule will lead to excess weight, and subsequently to obesity.
2. Does the value of the ideal weight depend on the physique?
Yes it depends. Before you start calculating your ideal weight, you need to determine your body type.
The physique is of 3 types:
- asthenic,
- normosthenic,
- hypersthenic.
Solovyov's index allows you to determine the type of physique by the girth of the wrist (in centimeters).
Asthenic (thin-boned). The circumference of the wrist in women is less than 16 cm, in men it is less than 18 cm.
People with an asthenic body type are thin, not inclined to be overweight due to an accelerated metabolism, they are distinguished by narrow hips and chest. As a rule, growth is not lower than average, with elongated limbs and a "swan" neck. They may suffer from a lack of strength and endurance, complex due to excessive thinness (and this problem is much more difficult to solve than being overweight).
Normosthenic. The circumference of the wrist for women is 15-17 cm, for men 18-20 cm.
Those who are lucky enough to have a normosthenic type are proportionately built, usually of average height.
Hypersthenic. The circumference of the wrist in women is more than 17 cm, in men it is more than 20 cm.
Women of a hypersthenic physique can safely justify themselves that they have a wide bone. Their bones are really heavy, such ladies have broad shoulders, a massive chest and long legs. They can safely choose professions where physical strength and endurance are needed. It is this one that will stop a galloping horse, and enter a burning hut.
3. Does the value of the ideal weight depend on gender?
Yes, it depends.
Calculation of the ideal weight using the Lorenz formula(taking into account gender and height).
Ideal weight for men = (height - 100) - (height - 152) x 0.2.
Ideal weight for women = (height - 100) - (height - 152) x 0.4.
Height in centimeters, weight in kilograms.
Example.
For a man with a height of 160 cm, the ideal weight is calculated as follows:
(160 - 100) - (160 - 152) x 0.2 = 60 - 8 x 0.2 = 60 - 1.6 = 58.4 kg
For a woman with a height of 160 cm, the ideal weight is calculated as follows:
(160 - 100) - (160 - 152) x 0.4 = 60 - 8 x 0.4 = 60 - 3.2 = 56.8 kg
As you can see, with the same height, the ideal body weight varies depending on gender.
4. What formulas for calculating the ideal weight are the most accurate?
The most accurate are formulas that take into account gender, age, physique (at least height) or special tables developed by hygienists.
Broca's method, named after a French doctor in the late 19th century, is the most popular method for quickly assessing weight.
Broca's formula for people with a normal physique:
weight (ideal) = height - 100 (with height less than 165 cm);
weight (ideal) = height - 105 (with a height of 166 - 175 cm);
weight (ideal) = height - 110 (with height above 175 cm).
If you have an asthenic body type, then the result obtained is reduced by 10%, with a hypersthenic body type, increase by 10%.
Example.
With a height of 170 cm, the ideal weight for normosthenics will be: 170 - 105 = 65 kg
For asthenics: 58.5 kg (-10%).
For hypersthenics: 71.5 kg (+ 10%).
P.S. Now you can calm down: not everyone is given by nature to have model parameters, do not demand the impossible from yourself. Everyone has their own ideal weight.

Most of us have our own more or less clear idea of the optimal ratio of height and kilograms displayed on the display of bathroom scales. The modern beauty industry offers a huge number of images that are simply impossible not to admire, and therefore the number of people who are dissatisfied with their appearance is constantly growing. The desire for ideal forms pushes people to exhausting diets, the most difficult physical exertion, and in some cases even to the services of surgeons. In this regard, sooner or later the question arises: “How to calculate the ideal weight?” First of all, let's deal with this concept itself.
What should be understood by this?
Most often, a person is presented with some abstract figure, which he tries to achieve by any possible means. For some, celebrities serve as a guide, someone determines the desired figure for themselves, based on numerous articles actively posted in magazines and social networks, and someone strives to achieve the indicators that were the norm for them some time ago. It is simply impossible to calculate the ideal weight for a woman, a man, or even a child based on such conditions.
The thing is that this value has nothing to do with the optimal figures planned by us in our minds. Someone dreams of the cherished forty kilograms, but in reality this figure turns out to be either completely unattainable or dangerous to health. In order to understand how to calculate the ideal weight, you need to know exactly what is meant by this.
In fact, in most cases, this indicator is very far from those that people imagine in their dreams. The ideal weight is the number of kilograms that is optimal for a certain height, age and build. An indicator at which the body can fully function.
Concepts of beauty and norms
Calculating the ideal weight for height and age is not at all difficult, but for many the figures obtained lead to some disappointment. It turns out that, despite the full compliance with the parameters obtained, a person cannot boast of a beautiful body - the muscles can be flabby, there may be slight fat deposits in the lower abdomen or on the sides. The thing is that ideal weight is far from an indicator of attractiveness. That is why most nutritionists and fitness trainers advise measuring not kilograms, but centimeters, and remember that the shape of the body is determined by both body fat and muscles.
Basic Formula
In most cases, the basic parameter that determines the required number of kilograms is growth. You can calculate the ideal weight for a man, woman or teenager using a single formula.
For representatives of the stronger sex, subtract 100 from height (in centimeters). For the beautiful half of our planet - 110 or 115, if the girl is especially tall. It is this formula that most nutritionists offer when answering the question of how to calculate ideal weight.
Alternatives
Nevertheless, this is far from the only formula for determining this indicator. A huge number of nutritionists wondered how to calculate the ideal weight, and therefore there are a huge number of options for this procedure.
Formula #2
One of the most popular methods at the moment is the Paul Broca index. The author of the famous formula was neither a nutritionist nor a bodybuilder, he was engaged in surgery and anthropology, knowledge of the characteristics of the human body helped him in his calculations. In order to determine the ideal weight, you must do the following:
- BMI (men) \u003d (height in cm - 100) x 0.85.
- BMI (women) \u003d (height in cm - 100) x 0.9.
It should be noted that there are several more variations of this particular method, which are more or less close to the basic technique described above in our article.
Borngardt index
In general, the methods for determining this parameter are quite diverse. For example, you can easily calculate the ideal weight by age or taking into account other determining factors.
One of the most popular formulas among nutritionists is the determination of the Borngardt index. This is the only technique that uses chest circumference. The calculation is made as follows: (height in cm x chest girth): 240.
Augmented Brock's index (calculated by Kref)
Among the more complex definitions, one can single out, for example, the Kreff formula, in which the scientist finalized the already existing and described Broca index, supplementing it with indicators of build and age. You can determine the ideal weight according to Kreff as follows: (height in cm - 100 + (age: 10)) x 0.9 x physique coefficient.
The last parameter is determined by measuring the girth of the wrist.
- If girth is less than 15 cm, coefficient = 0.9.
- If the girth is from 15 to 17 cm, the coefficient = 1.
- If more than 17 cm - 1.1.
Formula of the ideal figure
Among other methods, one can single out a rather amusing formula, developed by professional nutritionists, book authors Robert Cooper and Leslie Cooper. According to their book Fat Free Super Diet, ideal weight can be calculated using the following formulas:
- IMZH \u003d 0.624 x height - 48.9.
- IMM \u003d 0.713 x height - 58.0.
Latest developments
Dietology, like the beauty industry, does not stand still, and therefore developments in this area are continuously ongoing. One of the latest formulas for calculating ideal weight was developed quite recently - in 2010. It corrected the errors that existed in the previous versions, associated with excessively high or too small growth. In general, Mohammed's formula for calculating the ideal weight is as follows: height in cm x height in cm x 0.00225.
The principle is the same for both women and men.
The approach of insurance companies
The developer of this particular technique was Metropolitan Life. Using these calculations, the company's specialists determined for their clients the ideal weight at which the risk to health would be the least. The definition is made according to the following formula:
- IV \u003d 50 + 0.75 x (height in cm - 150) + (age - 20): 4.
This technique has only one feature that should not be forgotten. It is not suitable for people under 25 and over 59.
One of the most popular diets
At the moment, the weight loss method developed by Pierre Ducan, a French specialist in the field of safe weight loss, is becoming more and more popular. The whole system of bringing the body into perfect condition includes 4 stages. The first of them - "Attack", is considered the most aggressive, at this time the body is actively spending calories, and centimeters are melting at a double speed. The second stage is called "Alternation". Protein days during this period are replaced by vegetable ones, and its duration will be longer. The longest stage is the "Fixation". It is necessary so that extra pounds do not return to their place after the completion of the diet. The last step will be weight stabilization.
Calculating the ideal weight according to Dukan is not at all difficult - there are a huge number of online calculators in which you just need to enter your data to get the result. The calculation system takes into account parameters such as height, weight, age, level of physical activity, body mass index, so the results obtained in the end are quite accurate.
All those who lose weight are interested in the question of the norm. What weight is considered normal for yourself? There are a number of formulas, using which you can determine to what extent your body weight corresponds to one or another average value. After all, all these formulas are derived from the calculation of the average person. Therefore, resorting to them, one must clearly realize that any formula for normal weight is conditional.
In reality, each of us has our own individual genetically predetermined value of the optimal body weight, which depends on the totality of innate structural features of the tissues and organs of the body as a whole.
So, for example, there are three body types - asthenic (thin-boned / ectomorph), normosthenic (normal / mesomorph) and hypersthenic (big-boned / endomorph).
To determine your type, you need to measure the circumference of your wrist.
- Less than 16 cm - asthenic;
- 16-18.5 cm - normosthenic;
- More than 18.5 cm - hypersthenic.
- Less than 17 cm - asthenic;
- 17-20 cm - normosthenic;
- More than 20 cm - hypersthenic.
In addition to body types, the body of each of us is programmed for a certain weight. This program is included by the mother during pregnancy. It is believed that if she gained excess weight during pregnancy, then the child may have difficulty in controlling body weight in the future. In the course of our lives, both wrong and we are laying another program. During weight loss, many are faced with the so-called balance point or set point, when using healthy methods, and if it works out, then they can’t keep it.
For example, you weighed 90 kg, lost weight to 55 kg, want to lose another 5 kg, but it doesn’t work out no matter what you do. At the same time, even arranging a rest from the diet and small holidays, you do not gain more than 3-5 kg, which you then easily lose. Perhaps you have reached your point of balance, and overcoming it can cost you dearly. When the body is under constant stress, and diets, training and high demands on oneself are constant stress, the risk increases. It is important to listen to yourself and the needs of your body.
If you do not take into account the individuality of the body and physique, then in approximate calculations you can use the following simple formulas (author P.P. Broca, 1871):
For men
(Height in cm - 100) x 0.9 = ideal weight.
For women
(Height in cm - 100) x 0.85 = ideal weight.
There is another formula that can be used for both men and women:
(height in cm - 100) = ideal weight.
Example: If your height is 152 cm, your weight should be 152 - 100 = 52 kg.
There is another formula:
Height in cm x Bust in cm / 240 = ideal weight.
Example: (155 x 96) / 240 = 62 kg.
Do not forget that it is necessary, nevertheless, to take into account the physique, that women naturally have more fat than men.
Therefore, you can use the following data to determine your ideal weight:
For men
| Height, cm | Body type | ||
| Thin (asthenic) | |||
| 155 | 49 kg | 56 kg | 62 kg |
| 160 | 53.5 kg | 60 kg | 66 kg |
| 165 | 57 kg | 63.5 kg | 69.5 kg |
| 170 | 60.5 kg | 68 kg | 74 kg |
| 175 | 65 kg | 72 kg | 78 kg |
| 180 | 69 kg | 75 kg | 81 kg |
| 185 | 73.5 kg | 79 kg | 85 kg |
For women
| Height, cm | Body type | ||
| Thin (asthenic) | Normal (normosthenic) | Broad bone (hypersthenic) | |
| 150 | 47 kg | 52 kg | 56.5 kg |
| 155 | 49 kg | 55 kg | 62 kg |
| 160 | 52 kg | 58.5 kg | 65 kg |
| 165 | 55 kg | 62 kg | 68 kg |
| 170 | 58 kg | 64 kg | 70 kg |
| 175 | 60 kg | 66 kg | 72.5 kg |
| 180 | 63 kg | 69 kg | 75 kg |
Ideal weight formulas help you figure out how much weight you can lose. However, it is important to understand that two people with exactly the same weight can look completely different. It's not about height or body type, it's about body composition - the ratio of muscle to fat. Look at the photo.
Adipose tissue is more voluminous than muscle tissue. Therefore, the girl on the left looks more curvaceous than the girl on the right, although they have the same weight. And that is why it is so important to strive not so much to lose weight as to strengthen muscles with the help of strength training and.
Imagine a picture: wake up in the morning, take a shower, have breakfast. And when the time comes to put on your favorite jeans, we realize with horror that we can’t fasten them - the stomach interferes. We climb under the sofa, find dusty floor scales, get up on them and ... A familiar story, right?
Whatever figure is displayed on the scales, frustration and depression are received - jeans are not to be worn now. What to do? You can just score. Throw your pants in the trash or shove them into the farthest corner of the chest of drawers - let them lie there until better times. And you can go the other way - throw off a couple of other 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 into a fist and decide to lose weight. But before starting, another question arises - what to strive for, how many kilograms you need to lose, so that it is completely good: both pants so that they fit, and breathe easier, and on the beach so that in the summer it would not be a shame to get out. We are thinking, trying to figure it out - how to calculate your ideal weight?
It turns out that the ideal (correct) weight is an abstract concept, and it denotes an average value obtained on the basis of a set of given physiological parameters of a person, such as height, age, gender, and body type. But the state of health, the level of physical activity, the percentage of fat mass in relation to muscle mass and other individual indicators of a single 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 we can rely on when reducing or gaining body weight.
The most famous types of weight calculation by formulas:
- Calculation of weight by height
- Calculation of weight by age and height
- Calculation of weight by BMI (body mass index)
Calculate weight by height
A simple method known more as Brokk's formula. The 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 for a woman with a height of 170 cm - 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 for a woman with a height of 170 cm - 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 a person’s body weight, then the Egorov-Levitsky table, as it is also called, displays the maximum allowable weight value, the excess of which is considered unacceptable for a given height and age group.
All you need to know is your height, age and actual weight. Look for the intersection of these parameters in the table and understand how far you are from the maximum allowable value. If the figure in the table is higher than your existing weight, it’s good, if it’s 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. Crossing over the table shows the maximum weight value of 75.8. A woman is one step away from this value. Therefore, close control of body weight is needed, otherwise it is possible to go beyond the permissible limits.
Calculate weight by BMI (Quetelet body mass index)
table for calculating the optimal weight by Quetelet's body mass index
With the help of the Body Mass Index, you can find out in which predetermined range a person’s weight is at the current moment: deficiency, normal or obesity (all BMI values are shown in the table).
BMI is calculated using a formula that uses baseline 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 \u003d 88: (1.85 * 1.85) \u003d 27.7. We are looking for a value in the table and we understand that the index is in the range of Overweight (pre-obesity).
An important point: the calculation of 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, whichever method of calculating the correct weight you choose, the result of the calculations should not be taken as an absolute truth. All figures will be approximate and indicative. And jeans from these calculations still won't fit. So dumbbells in your hands, legs in sneakers, a lock on the refrigerator and forward - towards the result.
Options for calculating normal weight and body volumes for different heights.
Now many girls are passionate about their figure, this is due to the fashion for fitness girls. The saddest thing is that weight increases with age and there is nothing to worry about. Despite this, many of the fair sex react very sharply to the gained kilograms. In this article, we will tell you how to determine the ideal weight and volume parameters for your height and weight.
To determine the Quetelet index, you need to raise your height in centimeters to the second power, that is, squared. Just multiply your height by that number. Now divide the weight by the amount received and multiply by 100. The optimal number for women is 19-24, and for men 19-25. The table shows the BMI norms and the risk of getting serious illnesses.
Another option for determining the ideal weight is Brock's formula. Many people think that it is enough to subtract 110 from height, this will be the ideal body weight. This is actually a very simplified formula. Correctly subtract 100 from the length in centimeters, with a height of up to 165 cm. If your height is in the range of 165-175 cm, then you need to subtract 105. If you are more than 175 cm, subtract 110.
But these are not final calculations. Body type is also of great importance. The fact is that people with the same height and weight look completely different. This is due to the different ratio of body fat and muscle mass, as well as bone thickness. If you have a wide bone, then add 10% to the weight obtained according to the formula, if you have thin wrists and ankles, then, on the contrary, subtract 10%.
For example, two and girls with a height of 168 cm should weigh 63 kg. But if a lady with thin bones and small muscle mass, 63-6.3 = 56.7 kg must be subtracted from this figure. If the girl is large in itself, that is, with a wide bone, then her ideal weight with a height of 168 cm will be 63 + 6.3 = 69.3 kg. Moreover, if you compare the external data of these girls, you will not see much difference.
There are 3 main body types:
- thin-boned(asthenic) body type. Such women are quite thin, but they also gain weight very quickly. Their body weight is highly dependent on nutrition. They are active and energetic, metabolism is good. But the muscles are weak and the bone is thin.
- Normal(normosthenic) body type. Women of this physique were lucky. As a rule, they have a beautiful, proportionally folded figure. The main dimensions of the body differ in the correct ratio.
- broad-boned(hypersthenic). Such women themselves are quite large, while the amount of fat they have is relatively small. The muscle mass is decent, and the bone is wide. They are short in stature and have short legs.
To determine the type of physique, it is enough to measure the circumference of the wrist of the working hand: for asthenics it is less than 16 cm, for normosthenics - from 16 to 18.5 cm, for hypersthenics - more than 18.5 cm.
There are many formulas for calculating the waist circumference:
- The simplest can be considered the calculation of waist size by height. To do this, subtract 100 from the height of the body. That is, with a height of 169 cm, your waist should be 69 cm. But this applies to women with normal bone thickness. If the girl is thin-boned with undeveloped muscles, then here the value can decrease by 4-6 cm. And vice versa, if the lady has a wide bone, then 4-6 cm can be added to the resulting value. The figure will be 75 cm.
- This is not the only way to calculate waist measurement. Psychology professor Singh found that the most correct and attractive are women whose waist is 60-70% of the hip circumference. For example, if the hips are 100 cm, then a waist of 60-70 cm can be considered ideal.
- Many professors believe that to get an ideal waist, you need to subtract 30 cm from the hip circumference. In principle, with a hip circumference of 100 cm, the waist should be 70 cm. Doctors and endocrinologists believe that a person is absolutely healthy if the waist circumference does not exceed 85% of the hip circumference . This means that a person does not have obesity and thyroid problems.
There is an ideal ratio of women's weight and height, and each specialist suggests calculating the value using his own formula. The easiest way is to subtract 100 from height, but if you are younger than 30 years old, then calculate another 10-12% from the resulting mass. This will be the ideal weight. But if you are over 50 years old, then vice versa, add 5-7% to the resulting figure.
There are several common methods for calculating ideal weight. For example, the Lorenz formula:
Weight \u003d (height - 100) - (height - 150) / 2
That is, for a girl with a height of 169 cm, we get:
(169 - 100) - (169 - 150) / 2 = 59.5 kg
But many doctors note that this weight is more suitable for women under the age of 35 with a normal physique. With a wide bone, you can safely add 5-6 kg to the resulting mass. The same must be done if you are over 50 years old.
There are several tables of the ratio of normal height and weight by age. With age, the metabolism worsens, respectively, body weight increases. To determine your ideal weight, use the table.
The most interesting thing is that slender women not only look better, they are healthier than their plump girlfriends.
Benefits of being thin over being overweight:
- Reduces the risk of cardiovascular disease. Usually, overweight women overeat, so cholesterol in the blood increases, which can lead to heart disease.
- Decreases the chance of getting cancer. The amount of cholesterol is lower, weight is less, immunity is better. Accordingly, the whole body is stronger.
- Normal pressure. In women, pressure in the body constantly jumps, but thin women do not have such a problem.
- The risk of getting arthrosis is reduced. The more weight, the more pressure on the joints. That is, the cartilage and the lubricant between the bones wear out quickly.
- Physical activity is easier. The lighter the weight, the easier it is to run up stairs and behind vehicles.
If your parameters do not fit into the ideal at all, do not be discouraged. This means you have something to strive for and not relax.

Strange thing: my parameters are 83-58-60-83-84. If we subtract 30 from 83, we get 55. You generally know a lot of women with such a waist. Looking at me, people look with bewilderment, many say that such a thin waist have not yet seen anyone, but 50-55 ... Mom had one like that, but she is only 150 cm tall. There are, of course, unique ones with a waist of 20 cm. But, firstly, this is artificially achieved, secondly, it looks terrible: a huge head, shoulders that seem to be shirlchenny against the background of such and such a waist and shirlchennyn hips in comparison with the waist. Some kind of dinosaur, or fat, excuse me. , of course, the matter is also in the constitution. I have a sharp transition from the chest, which is somewhat expanded, to the waist. And before I was 11 kg fuller, the waist swam fat, its girth was about 70 cm and still it was noticeable. weight, I should have been considered a bun on legs, but it was not at all like that, although my problem is that I am not thin, not sinewy, moreover, I am too fat fat layer and friability of the skin from nature. one). With my disgusting metabolism, losing weight is extremely difficult for me and with great sacrifice. If I knew what I would sacrifice, I would not lose weight for the last time. My sister is thin, although now she weighs more than me, but she does not look so soft and feminine, however, she has almost no waist. Just a long, thin body, without the curves characteristic of a female figure. I also like these types. Despite the absence of a thin waist, they are not subject to fullness, even with age. changes their appearance. Lucky. They always look toned and athletic. Neither the hips nor the waist are fat. I don’t even know where it is deposited at all. painful, not athletic and thin. Well, what to do, no luck ...
