Table of the ratio of height and weight for women. The correct ratio of height to weight in men
Height to weight ratio
There are different formulas for determining the optimal ratio of weight and height... But they are all conditional, since they do not take into account many other factors. Therefore, the excess fat should be assessed not only by these ratios, but also by the appearance, the thickness of the skin fold, etc. With the same height and weight, one person may look fat, the other is completely normal.
The best indicator of body fat ratio
The objective parameter of an ideal body is the percentage of fat and musculoskeletal tissue. For men, the norm is 9-15% of total body weight, and for women - 12-20%.
Quetelet index
Knowing the Body Mass Index (BMI), you can judge obesity or lack of weight. The index is calculated for adult men and women from 20 to 65 years old. Results can be false for pregnant and lactating women, athletes, the elderly and adolescents (under 18). Among the many different methods for calculating the ideal weight, the most popular method is the height-weight indicator, the body mass index is the 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, obviously, shows the amount of fat in the body quite well, but does not indicate how fat is distributed in the body, in other words, it does not give a visual and aesthetic picture.
Thus, you can check your body for ideality using one more formula. The distribution of body fat is determined by the ratio:
waist (navel) / buttocks.
The norm for men is 0.85
For women - 0.65 - 0.85.
Does age affect the height-to-weight ratio?
The answer is unequivocal. Yes, of course it does. It is proved that the weight men and women should gradually increase with age - this is a normal physiological process. The kilograms that some people think are "unnecessary" may not actually be. Can be used to determine the optimal weights formula depending on age. P - in this case, height, and B - 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 Broca's formula. She takes into account ratio of height, weight, body type and age of a person. And Broca's Formula for people under 40 is equal to "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 (large-boned) body type should add 10% to the result.
How to determine your body type?
The physique is usually divided into 3 types: normosthenic, hypersthenic and asthenic. In order to find out what your body type is, it is enough to measure the circumference of the thinnest place on the wrist with a centimeter. The resulting circle in centimeters will be the necessary indicator (Solovyov index).

In people with a hypersthenic (broad-boned) body type, the transverse dimensions of the body are much larger than in normostenics and especially asthenics. Their bones are thick and heavy, their shoulders, ribcage and hips are broad, their legs are short. |
|
less than 18 cm |
less than 15 cm |

In people with an asthenic (thin-boned) body type, the longitudinal dimensions prevail over the transverse ones: the limbs are long, thin bone, the neck is long, thin, the muscles are poorly developed. |
Nagler's formula for height-to-weight ratio
There is Nagler's formula that allows you to calculate the ideal weight-to-height ratio. For 152.4 cm growth should account for 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 Formula for Girth Ratio
One of the best formulas created by expert methodologist John McCallum. McCallum's formula is based on measuring the girth 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 the waist circumference, you need to take 70% of the chest circumference.
4. 53% of the chest circumference is equal to the thigh circumference.
5. For neck girth, you need to take 37% of the chest girth.
6. The biceps girth is about 36% of the chest girth.
7. Calf circumference slightly less than 34%.
8. The girth of the forearm should be equal to 29% of the girth of the chest.
But not all physical data will exactly correspond to these ratios, since they assume that the size of the wrist is rigidly related to the size of all human bones. And for some it is not so.
Some more height-to-weight ratios
The physique is considered ideal if the waist circumference is 25 cm less than the hip circumference, and the thigh 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 folded in proportion if the waist circumference is 72 cm, the circumference of the hips and waist 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 girth of the chest is less than the girth of the hips, and the girth of the waist is 30 cm or more less than the girth of the hips, this is a pear-shaped figure.
For women and girls of average height - from 165 to 175 cm - this observation turned out to be true. 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 results of calculating BMI are not suitable for assessing the weight of professional athletes, pregnant women, as well as people suffering from edema and other disorders, leading to an incorrect assessment of the initial data.
Weight ranges in this calculator are calculated for height, according to the methodology of the World Health Organization (WHO).
The very method of assessing weight by BMI is intended for the primary detection of underweight or overweight. Obtaining an assessment that is different from the norm is a reason for contacting a nutritionist and endocrinologist in order to conduct an individual assessment of weight and develop recommendations for its correction, if necessary.
The ideal weight range (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 of normal weight looks not only healthy, but also the most attractive. If you are adjusting your weight, then it is highly discouraged 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 weight loss disorder.
Weight loss is also typical for professional models, gymnasts, ballerinas or girls who are overly addicted to weight loss without the supervision of a nutritionist. Unfortunately, this can sometimes lead to health problems. Therefore, weight correction in this range should be accompanied by regular medical monitoring.
Norm shows the weight at which a person has the maximum chances of staying healthy for 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, those of normal weight tend to be in good health even after intense physical exertion.
Preobesity speaks of 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, light weight correction is recommended to normal, or to values close to it. Also, it will not hurt to consult a dietitian doctor.
Obesity- an indicator of chronic disease associated with excess body weight. Obesity invariably leads to problems with the cardiovascular system and significantly increases the risk of acquiring other diseases (diabetes, hypertension, etc.). Obesity treatment is carried out exclusively under the supervision of a dietitian or endocrinologist, and only after the necessary tests and determination of its type. It is not recommended to engage in uncontrolled diets and serious physical activity with obesity, as this can provoke additional problems.
Answers on questions
What is the ideal weight for me?
The calculator calculates the weight range that is ideal for you based on the specified 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 received estimate?
Yes. Adult weight estimates are based on authoritative research from the World Health Organization (WHO). Evaluation of weight from birth to 18 years is carried out according to a separate special method, also developed by WHO.
Why gender is not taken into account?
The BMI of adults is estimated in the same way for both men and women - this is justified by the results of statistical studies. At the same time, for weight estimation, gender and age are of fundamental importance.
Some other weight calculator will give you a different result. What to believe?
There are many calculators available 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 you do not know or do not suit (for example, formulas for evaluating athletes).
The WHO recommendations used in this calculator were developed for ordinary modern people, taking into account the conditions of modern life, the achievements of medicine and based on fresh observations of the population of all continents of the planet. Therefore, we only trust this technique.
I believe the result should be different.
The assessment is made solely on the basis of the data you provide for height and weight (as well as age and gender for children). If you receive unexpected results, please double-check all the entered data. Also, make sure that you do not belong to any weight that cannot be estimated through BMI.
My result is a lack of body weight, but I still want to lose weight
This is not unusual, many professional models, dancers, ballerinas do just that. However, in this case, it is recommended to lose weight only under the supervision of a dietitian 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 doing fitness, after consulting a good nutritionist.
Please note that some elements of the figure are practically not amenable to correction only with the help of fitness, exercise, diets, or their combination. Your goals should be analyzed by an experienced doctor in order to assess their reality, consequences and prescribe only the right procedures.
My result is pre-obesity (or obesity), but I disagree
If you are an athlete with increased muscle mass, then BMI weight estimation is simply not intended for you (this is mentioned in). In any case, for an accurate individual weight estimate, consult a dietitian - only in this case you will receive an authoritative result with a doctor's seal.
Why am I considered too thin or fat when my weight is normal?
Pay attention to the personalities and weights of those people who bother you. As a rule, they judge exclusively by themselves: subjectively. Fat ones always consider the thin ones to be skinny, and the thin ones consider the fat ones to be fat, moreover, both of them can have a weight within a healthy norm. Consider social factors as well: try to exclude or suppress those judgments in your address that are based on ignorance, envy, or personal dislike. Trustworthy is only an objective assessment of BMI, which clearly indicates the norm, excess or deficit of mass; and only trust supportive people in your weight class or your doctor for your worries about your figure.
How to calculate body mass index (BMI)?
The weight indicated in kilograms must be divided 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
As they develop, each child grows and gains weight. Parents who are concerned that the baby grows "correctly" always pay attention to "normal" body weight and height, focusing on the average data given in the tables of the World Health Organization. Answering the question about how much a child of a certain age should weigh, it should be borne in mind that the body of each person has individual characteristics. That is, in order to understand that everything is in order with the child and he is growing normally, one must not only compare his parameters with the standard, but also take into account their ratios.

The ratio of growth parameters and body weight of a child
This article tells about typical ways of solving your questions, but each case is unique! If you want to know from me how to solve your particular problem - ask your question. It's fast and free!
The concept of "body mass index" is well known to many parents - especially mothers who are looking after their figure. To assess the harmony of the child's development and identify possible deviations in height and weight, you will also need to calculate the BMI.
It is important to remember that the indicators of the norm for a baby differ from those calculated for the adult population. The normal BMI of an adult is no more than 25; for children, a similar index can vary between 13-21. BMI is calculated to diagnose the following conditions:
- obesity requiring treatment;
- overweight;
- slightly increased weight, which is within the permissible range of fluctuations in the norm;
- normal weight (see also:);
- underweight;
- emaciation requiring treatment.
Features of the first year of a baby's life
In the first twelve months of a child's life, indicators of his growth and development are directly related to the characteristics of feeding. In accordance with the WHO guidelines, a breastfed baby with a birth weight of 3.3 kg (boy) or 3.2 kg (girl) is taken as a reference in the development of the table. According to the growth rates, the "starting indicators" are taken equal to 49.9 cm and 49.1 cm, respectively.
If the baby was born with a smaller body weight and height (this is often the case in children born prematurely, as well as in those born of short parents), then there is no need to worry that after a month or two he "lags behind" from tabular indicators.
Until the age of one year, the decisive importance is not the correspondence of height and weight to the table, but their change over time. If the child is systematically gaining pounds and growing, then everything is in order with him, and there is no reason for panic.

Height and weight of boys
The characteristics of the weight and height of male babies until they reach the age of one year are determined according to the same principles as for girls. The monthly weight gain is of decisive importance for monitoring the condition and development of the child - that is, you need to compare the baby first of all with himself, as he was a month ago.

Indicators of a child under 10 years old
The period from birth to the age of 10 is characterized by the rapid growth of the child. However, if up to one year old the baby was growing noticeably and "heavy" almost every day, at an older age it will grow a little slower.
This is due to changes in metabolism and to the growing activity of the baby: the baby spends much less energy and calories on outdoor games than the toddler, who has already learned to walk and run, and now actively learns the world around him.
Baby's height and weight at 1 year old
If we turn to the average values, then it can be noted that during the first year of life, the baby gains about 6-7 kilograms. Moreover, most of the "increase" falls on the first six months of life, when the child adds about 700-800 grams in one month. With proper care, healthy low-birth-weight babies by 6-7 months can "catch up" by weight of their peers born with an average body weight.
The weight of a one-year-old child is considered normal if its value is in the range between 8 and 12 kg. The increase in height in this case will be about 25 cm. The height of a child at 1 year is approximately 75 cm ± 6 cm.
Height and weight from 2 to 3 years
Between two and three years old, the baby is still growing. However, less and less quiet rest and meals remain in his daily routine, and the amount of time devoted to outdoor games is steadily growing. Normally, in the third year of his life, a child will gain about two or three kilograms (that is, it will weigh 11-15 kg) and grow by 9-10 cm.
Height and weight from 4 to 5 years
According to the WHO, the average weight of a harmoniously developed 4-year-old baby is about 16 kg, while a deviation of 2-3 kg up or down is considered a variant of the norm. The growth of a baby of this age is 102-103 cm.By his fifth birthday, the preschooler will gain about 2 kg and grow by 7 cm.
Height and weight from 6 to 7 years
If you put a healthy six-year-old baby on the scales, and the screen displays a value from the range of 18-23.5 kg, then it fully complies with the standards developed by the WHO. By the age of seven, a senior preschooler (or junior schoolchild) will become 2-3 kg heavier. According to the growth rate, it will grow by about 5 cm.
Summary table with parameters from 1 to 10 years
For those parents who are worried about the development of their baby, it will be useful to familiarize yourself with the summary table of the growth and weight of children, compiled according to the WHO. Shown here are the average heights and weights for children of both sexes, ages 1-10. The baby's parameters do not have to exactly correspond to the values given in the table - a deviation of 2-3 kg and a few centimeters in either direction is considered a variation of the norm.
It should also be borne in mind that girls grow intensively after 10 and up to 12 years, in boys, a jump is observed at an older age - after 13 and up to 16 years. Girls gain in height on average up to 19 years old, and boys up to 22 years old.

Indicators for children from 11 to 18 years old
Indicators that are considered normal at the age of 11-18 years differ in their wide range. This is the period of the onset of puberty, when global changes take place in the adolescent's body. Parents need to prepare a growing son or daughter not only physically but also emotionally.
It should also be borne in mind that it is not recommended to follow a diet for weight loss at this time - a lack of necessary elements in the period before the age of 18 can lead to serious problems in the future.
The growth rates and body weight of children are presented below.

Factors Affecting Growth Rate and Weight Gain in Children
Growth rate and weight gain are influenced by a number of factors. First of all, it is, of course, heredity. If the parents of the baby are not tall and have an asthenic physique, then with a high degree of probability the indicators of the child's body weight and height will be similar.
Imagine a picture: we 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 cannot fasten them - the stomach interferes. We climb under the sofa, find dusty floor scales, stand on them and ... A familiar story, isn't it?
Whatever figure is displayed on the scales, frustration and depression are obtained - jeans cannot 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. Or you can go the other way - to throw off a couple of extra extra pounds - maybe the trousers will fit.
The second option is more difficult - you need to do something, waste time, make efforts. However, we clench our will into a fist 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 be completely good: so that the pants fit, and it is easier to breathe, and to the beach so that it will not be ashamed to get out in the summer. Thinking, trying to figure out - how to calculate your ideal weight?
It turns out that 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 characteristics, and constitutional features. But health status, 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 on which to rely on weight loss or gain.
The most famous types of weight calculation by formulas:
- Weight calculation by height
- Weight calculation by age and height
- Weight calculation by BMI (body mass index)
Calculate weight by height
The simple method is 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 it 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 for 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 real 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 - well, if it is 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 the table shows a maximum weight value of 75.8. The woman is one step away from this meaning. Consequently, close control of body weight is needed, otherwise going beyond the permissible limits is possible.
Calculate weight by BMI (Quetelet body mass index)
table for calculating the optimal weight by body mass index Quetelet
Using the Body Mass Index, you can find out in which predetermined range a person's weight is at the current moment: deficiency, norm or obesity (all BMI values are given in the table).
BMI is calculated using a formula that uses the original 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 weighing 88 kg will have a BMI = 88: (1.85 * 1.85) = 27.7. We are looking for a value in the table and understand that the index is in the Overweight (pre-obesity) range.
An important point: calculating the correct weight by 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 will still not fit. So dumbbells in hands, legs in sneakers, lock on the refrigerator and forward - towards the result.
Many people strive to lose weight by adhering to their own ideal standards. However, in pursuit of the parameters of the figure of a top model or actress, you can overdo it and harm the health of the body. Remember that the optimal human body weight is always calculated individually. Therefore, it is important to calculate the correct body weight. There are several formulas for this, and there is also a special weight and height calculator for men and women.
Before talking about how to calculate the ideal weight, we note that each of us has an individual genetically predetermined value of the optimal body weight. It depends on congenital characteristics, the structure of the body. Therefore, any calculation of the norm of weight is conditional.
What determines the ideal weight of a person
Before moving on to the ideal body weight formula, it is important to understand what criteria influence the determination of the ideal body weight. First, it is the gender of the person. A woman has a greater amount of body fat by nature. Secondly, the body type (normostenic, hypersthenic and asthenic). Third, height and age play a significant role in calculating the ideal weight. For example, it is much more difficult for people over 40 to lose weight due to the ongoing restructuring of the body.
The hereditary factor also plays an important role. If at the genetic level there is a predisposition to be overweight, it is much more difficult to get rid of extra pounds. If we discard this factor, you can find out the weight rate in men and women using various formulas, we will consider each of them in more detail.
Body weight formulas for men and women
There are different weight and height calculators for adults and teenagers, but the easiest and surest way is to calculate the ideal weight for height yourself. There are many formulas developed by scientists that allow you to find out weight by height.
Brock's formula
French physician Paul Brock has developed a formula for the ratio of weight and height, which is still considered one of the most universal. The formula takes into account not only height, but also the physique (thin, normal, stocky) and age.
The formula for the ideal weight according to Brock is as follows: height - 100. If a person has a thin physique, you need to subtract 10%, and if there is a stocky one, add 10%.
If the height is less than 165 cm, subtract 105, if higher than 175 cm, subtract 110. You should also take into account the age. People from 20 to 30 years old need to reduce the rate you get by 10-12%. If you are over 50, increase it by 5-7%.
Lorentz method
Calculation of the optimal weight for women: (height - 100) - 0.25 x (height - 150).
Ideal weight formula based on height and age
Weight norm in women by age and height: 0.9 × (50 + 0.5 × (Height, cm - 150)) + 0.5 × (age - 20)
Weight and height formula for men: 1 × (50 + 0.5 × (Height, cm - 150)) + 0.5 × (age - 20)
Normal weight and height charts
In addition to special formulas, there are weight and height tables for men and women.
Quetelet index
We present the table of the norms of weight and height for adults from 20 to 65 years old. Please note that this calculation of weight and height for undergrowth, pregnant women, athletes and the elderly from 65 years old will not work.
The result obtained must be compared with the table of height and weight for girls and men:
Calculation of the ideal body weight of an adult Quetelet
This author has another table of ideal height and weight, taking into account the age and physique of a person. To find out the ratio of weight, height and physique, divide weight in grams by height in centimeters. Compare the result with the parameter in the specified cell, regarding your physique. The main criterion is to be honest with yourself when assessing physique.
Example: Let's calculate the normal weight with a height of 175 cm, age 25, weight 60 kg and a normal physique: 60,000 / 175 = 342, 8. This is a normal index for a given person.
Table of weight and height of an adult Egorov-Levitsky
To calculate the weight for a man and a woman using this table, you just need to compare the data. Be careful, here is not the ideal weight for men and women, but the maximum. Also remember that the table shows the height and weight of an adult from 20 to 69 years old.
