Find out your weight without weights calculator. How to determine your normal weight by height

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 calculated taking into account growth, 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 of 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 slight correction of weight to normal, or to values ​​close to it, is recommended. It also does not hurt to consult a nutritionist.

Obesity- index 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 treatment is carried out exclusively under the supervision of a nutritionist or endocrinologist, and only after necessary analyzes and definitions of its type. It is not recommended to engage in uncontrolled diets and serious physical exertion for obesity, 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 life expectancy, 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?

Exists great amount calculators designed to estimate 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 based on common modern people, subject to conditions 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.

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 experienced doctor to assess their reality, consequences and prescribe only the correct procedures.

My result is pre-obesity (or obesity), but I do not agree with this

If you are an athlete with a high muscle mass, then the BMI weight estimate 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 weight within healthy norm. Take into account social factors: try to exclude or stop 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 anxieties about the figure only to supportive people of your weight category or a doctor.

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, with a height of 178 cm and a weight of 69 kg, the calculation will be as follows:
BMI = 69 / (1.78 * 1.78) = 21.78

Who doesn't want to look good and feel slim? But it is not always clear how to calculate the ideal weight, what figure to strive for and whether it is necessary at all.

There are girls who are sincerely sure that they need to lose weight, but in fact, the opposite is true for them - they need to get better. There are women who believe that everything is in order and a few extra pounds have no influence. Although medical statistics says the opposite.

In order to more objectively assess your weight, there are formulas for calculating excess weight. They are also not perfect, they have a number of drawbacks. But they allow you to reconsider your view on the issue of excess weight. You will find the most famous formulas for calculating ideal weight in this article.

Determination of ideal body weight

The ways we talk about are different from each other. And to some extent reflect the evolution of calculation methods ideal mass body. From the authoritarian method of Lorenz, which is suitable only for young girls. Before Broca's formula, taking into account body type and calculation formulas for age and height.
If you are curious, read the article with a pencil and paper in hand. But do not be strict about the resulting numbers. Not a single formula can describe the individuality, way of life, state of health and feelings in one or another weight of a particular woman.

First way. Lorentz method

The advantage of the Lorentz method: calculates the weight rate for those girls who are always 18. But seriously, this is one of the toughest methods that you should not be guided by.

The disadvantage of this method it is believed that it only works for girls, but not for guys. Also, you can not use it if a woman is taller than 175 cm.

According to this method, the ideal body weight for girls should be calculated as follows:

1. Measure your height in centimeters.
2. Subtract 100 from it.
3. The second action will be subtracting from the height of 150 centimeters.
4. Determine the difference between the first and second results.
5. The resulting units are divided in two.

This is how the formula for estimating body weight in a female looks like: (P - 100) - (P - 150) / 2.

For example: the girl has a height of 170 cm, we calculate: (170 - 100) - (170 - 150) / 2 = 70 - 20/2 = 60 kg.

The second way. Quetelet index

The advantage of the Quetelet index is versatility - it is suitable for both women and men.

The disadvantage of the formula is the inability to apply it to adolescents and the elderly. Also, you should not count on the objectivity of the method with very low or very high male and female growth. The method is valid for representatives of the stronger sex 1.68-1.88 meters, and the weak - 1.54-1.74 meters. He “lies” to pregnant, lactating mothers, athletes.

Important! The calculation of the correct weight norm begins with the calculation of BMI (body mass index).

Often, BMI is used by doctors to determine if there is obesity or dystrophy.

How to determine how many kilograms of overweight a girl has? Using the Quetelet formula, BMI is calculated:

1. Find out the mass of a person's body in kilograms using scales.
2. Measure height in meters.
3. The first indicator is divided by the square of the second.
4. They calculate and find their BMI in the table.
5. Know the result.

The method is accompanied by a table in which BMI is calculated by age:

For example: A 24-year-old girl has a height parameter of 1.59 m and weighs 61 kg. When calculating the weight norm for a woman, it turns out: 61 kg / (1.59) 2 = 24.1 (BMI). It turns out that there is a slight excess weight. If the girl were 2 years older, then her parameters corresponded to her age.

The third way. Brock's formula

Advantage: the technique of how to correctly determine the excess weight of a person according to Brock is suitable for people whose height is in the range of 155-200 cm.

Flaw: age is not taken into account.

Important! To find out the constitution of the body, you need to find the thinnest place on the wrist, and determine its circumference.

The measurement results are found in the table:

1. The number 110 is subtracted from the height in centimeters if the person is under 40 years old.
2. The older the man or woman, the more he (she) will weigh. After the age of forty a person, his parameter is calculated as follows: the number 100 is subtracted from height.
3. Also, a correction in the calculations is made for asthenic and hypersthenic types. In the first case, 10% is subtracted from the result, and in the second, the same percentages are added.

Example: you can determine the weight norm for a woman of thirty years as follows - 110 units are subtracted from her height of 167 cm. It turns out that her weight should be 57 kg. If she has an asthenic body type, the final result is: 57 - 5.7 = 51.3 kilograms, and if hypersthenic - then 57 + 5.7 = 62.7 kilograms.

Fourth way. Nagler's method

The advantage of the Nagler method The fact is that if you have data on growth, you can calculate the ideal number of kilograms for a girl.

Flaw: this formula is only valid for females. It does not take into account age and body type.

1. At 152.4 cm female stature take 45 kg.
2. Then, for each new inch (5.54 cm), another 0.9 kg is taken away.
3. At the end of the calculation, an additional 10% of the found weight indicator is added.

Example: the fair sex has a height of 170 cm. To calculate, we subtract 152.4 from 170 cm. This is equal to 17.6. We divide this value by the size of an inch - 2.54 cm. We get 6.93, and multiply by 0.9 kg. As a result, we have 6.24 additional kilograms. 45 kg + 6.24 = 51.24 kg. Add 10% of the resulting weight 51.24 + 5.124. The result - it should weigh approximately 56.364 kilograms.

Fifth way. Women's formula based on age and height

Advantage: this way takes into account age-related changes representatives of the fair sex.

disadvantage is that the method is only suitable for women. It does not reflect their body type in any way.

The norm of weight in most women gradually increases with age. This is due to the slowdown of metabolic processes in their body, and is a natural phenomenon.

This formula answers the question of how to determine the correct kilogram rate in a woman, taking into account age:
50 + 0.75 (Height - 150) + (Age - 20) / 4

Example: a woman is 42 years old, and her height is 168 cm. Find the ideal body weight:
50 + 0.75 (168 - 150) + (42 - 20) / 4 = 69 kilograms.

But we must not forget that we are all individual, and the ideal number of kilograms may differ from the calculated one - the main thing is that the person is comfortable.

In addition, the numbers on the scales often do not describe the state of the body and well-being, the ratio of fat and muscle tissue. Namely, they give beautiful curves and tightness.

What is your favorite way to calculate your ideal weight?

“My weight is far from ideal” - every time many women get upset when they step on the scales. But what is meant by the term "ideal weight"? What are the formulas for calculating it? And how does this figure change with age?

Zoya Iosifovna

In the arsenal of fighters overweight there are a lot of different formulas and methods for calculating body weight parameters. But to be completely honest, our weight is an individual concept and depends not only on the characteristics of each individual person (age, height, bone thickness, etc.), but also on the state of the body at a certain moment. Therefore, the so-called "weight" ideal does not exist.

It is customary for doctors around the world to use a body mass index (BMI) classification, which allows you to assess whether weight poses a threat to human health. BMI is calculated using the Cutla formula: a person's weight in kilograms divided by their height in meters squared. After that, the result is compared with the values ​​in the table. World Organization Health considers the ideal body mass index in the range of 18.5-24.99. Some experts interpret the interval 18-20 as insufficient, but safe for health.

It is clear that, according to this calculation, normal weight human has a fairly wide range of acceptable values. For example, with a height of 170 cm, the weight norm can be from 54 to 72 kg, if we take BMI from 18.5 to 24.99 as the norm. Some studies say that a BMI of 22 is ideal, and scientists from the American Cancer Society consider the most preferred BMI in the range of 21.3-22.1 for women and 21.9-22.4 for men.

When calculating the normal weight of a person, you can use other methods.

So, ideal weight = (height in cm - 100) - (height in cm - 150) / 2

For example:

The ideal weight for a 170cm woman is

(170-100)-(170-150)/2 = 70-10 = 60 kg

The same value can be reached even more in a simple way calculations: subtract the number 110 from the height in centimeters. For example, if your height is 165 cm, then the ideal weight for you is 55 kg (165 - 110).

Brokk has a similar formula, only not 110, but 100 is subtracted from height. Perhaps that is why it is recommended to use it only for men to calculate the ideal weight.

For the accounting age features from the resulting Broca's index, you need to subtract about 10% for people under the age of 30, and for people over 50, add about 5%.

These formulas are not very accurate, because they were developed a very long time ago and do not take into account some parameters. Advanced formulas are used on our website, by clicking on the link you can calculate the ideal weight automatically, using four different formulas.

You can also find out the optimal weight, taking into account age characteristics, from the table.

Table of optimal weight according to age

Having calculated or learned your normal weight from the table, do not rush to throw all your strength into achieving it. Indeed, in addition to the value expressed in kilograms, it is necessary to pay attention to the percentage of fat in the body. Sometimes a lot of weight is not caused by fat, but muscle tissue. In these cases, we can talk about the ideal weight even if the BMI is outside the "normal" range.

It is unlikely that you can measure the percentage of fat in the body "by eye", without the help of special instruments and scales with a given program. Therefore, modern nutritionists advise measuring deviations from the “fat” norm by waist circumference, since excess fat in this area carries health risks. So, for women, the waist should be no more than 88 cm, and for men - 102 cm.

If you have special devices that can calculate body fat, then a body fat content of 10-20% for men and about 25-29% for women is considered normal. At overweight a man's body contains about 25% fat, a woman's -30-35%. And with obesity in men, the weight of fat exceeds 30%, and in women - 35%.

The lack of fat also has a bad effect: less than 15% in women leads to disruptions in the normal functioning of the body.

Many people like to drink food. thin people can afford it, but those suffering from fullness - in no case. They need to drink before meals or some time after. You can drink only dry food: pies, crackers, sandwiches, cookies. But fruits and berries should not be washed down.

Problems with a lack of weight are almost at the level of problems with excess weight. Everyone has their own problems, as they say. One of the causes of underweight is a lack of appetite. Most often it occurs in children. The important thing in this case is...

The dream of a woman, and a conceived man, of an ideal weight will lead to the fact that sooner or later the question of the exact figures of the ideal will arise. In kilograms. Otherwise, we run the risk of escaping reality, and instead of the ideal weight, we strive for ...

Young girls are often worried about being overweight. Many girls entering adulthood weigh more than they should. Mothers, and sometimes doctors, tend to think that when girls start menstruating, they will lose weight, believing that girls are fat because they have "baby fat" that disappears on its own ...

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 physical activity, professions, 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 excessive pursuit perfect 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? For what? 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 worldwide as the simplest and most adequate indicator to quickly estimate 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 available methods, the calculation of BMI has its drawbacks. Please note that excessive or underdevelopment musculature can affect the accuracy of determining BMI.

How to correctly evaluate the result, taking into account age, gender and physical state? 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 do so simple rule will lead to overweight 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 in women is 15-17 cm, in 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, massive chest And long legs. They can safely choose professions where needed. physical strength and endurance. 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 asthenic type physique, then the result is reduced by 10%, with a hypersthenic type of physique, 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 Don't demand the impossible from yourself. Everyone has their own ideal weight.

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 in order to be completely good: both pants to fit in and breathe easier, and to 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)

calculation table optimal weight by Quetelet 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 understand that the index is in the range Overweight body (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.
