The ratio of height and weight in girls, women by age. Normal Weight Chart

Many modern girls follow the figure, try to be fit and slim. To determine the normal ratio of growth and weight parameters, it is necessary to know the norms and adhere to them, regulating body weight with nutrition and regular physical training.

What is BMI and why you need to know it

Scientific minds have long invented a formula for overweight or underweight. This is BMI. This abbreviation stands for Body Mass Index. According to this calculation, the main indicators of the human body are estimated.

The ratio of height and weight in a girl is necessary not only for determining beauty. Knowing how this formula works, one can suspect problems with the body or, conversely, not think about the possible risks.

What should be the ratio of height and weight

The formula is a road sign that shows whether life is heading in the right direction. Or it's time to change something.

There is an opinion that the optimal weight for a person is the same as in his younger years. But we should not forget that with every year of life, the human body does not get younger. The amount of muscle mass decreases, the body fat increases. And if you take the Quetelet formula (BMI) as the correct criterion for determining weight, then you can be very mistaken.

The correct calculation of this index can be influenced by both the body type and the amount of muscle and body fat in the body.

How to start determining the correct body proportions

The ratio of height and weight among girls in the modern world is very different even from those that were 20-30 years ago. Today, the beauty of a woman's physique is determined by: height, proportions of the upper body and lower extremities. But all numbers are relative.

To determine the parameters of your body, you need to take several measurements:

1. Measure height.
2. Find the location of the waist (it can be high, low and medium).
3. Measure the length of your legs.

Also, in addition, measurements of the neck, shoulders, hips, calf muscles, chest are taken. Together, all these indicators determine the proportionality of the physique.

How to measure height correctly

With age-related changes, growth also undergoes changes. Firstly, in the morning, a person's height is always 1-2 cm higher than in the evening. This is due to the fact that the body relaxes and stretches during sleep. Secondly, a person's height at 50 will not be the same as it was 20 years ago. Therefore, there is a need to make new measurements at regular intervals.

To measure your height correctly, you need to take an assistant and a hard meter. The tape should be left to measure the waist.

1. Stand straight on a vertical and level surface.
2. Press the heels, pelvis, shoulders and the back of the head tightly against the wall.
3. Press your chin to your chest.

In this position, at the top of the head (crown), the assistant needs to put a mark on the wall. Moreover, measurements are carried out strictly parallel to the floor. Measurement of the distance from the top point to the bottom - there is growth. Every woman or girl is different.

To say that someone is more beautiful is impossible. But there are categories of female growth:

• "Thumbelina" - height up to 155 cm;
• below average height - 155-165 cm;
• girls of average height - 165-170 cm;
• above average height - 170-175 cm;
• tall girls - 175-185 cm;
• too tall or tall - 185 and above.

Body types

The main classification of physique includes three types - this is an asthenic, a normosthenic and a hypersthenic (endomorphic view).

• Asthenic physique

The ratio of height and weight in girls with this type of figure is characterized by general leanness and graceful upper and lower limbs. Usually their height is 167-172 cm. Girls with this type of figure are very light, thin, elegant. They do not have a tendency to gain excess weight.

• Norman girls

A distinctive feature of this body type is the proportionality of the figure. These women are usually of medium height and have a very harmonious physique. With age, they can gain 2-3 kg of excess weight.

• Endomorphic type of women

This is a strong, stocky type of female build. Usually below average height. They are distinguished by a wide chest and broad shoulders. Girls with this physique are usually prone to gaining excess weight.

To determine your body type, you need to know the height, length of the legs and the volume of the wrist:

1. Asthenics - legs are 7-8 cm longer than ½ of the height. The girth of the wrist is less than 15 cm.
2. Normostenics - legs are 3-5 cm longer than ½ of the height. The circumference of the wrist is 15.5 -18 cm.
3. Endomorphs - the legs are a couple of cm longer than ½ of the height. The wrist circumference is over 18 cm.

There are also divisions by figure:

• A - shaped figure - has wide hips compared to narrow shoulders.
• X - shaped type of figure. Shoulders and hips are approximately equal in width. The waist is 20 cm less.
• H - shaped figure. Shoulders, waist and hips are approximately the same size.
• T - shaped figure. "Boyish" type - broad-shouldered with narrow hips.
• O - shaped physique. This type of women is distinguished by the most voluminous part of their figure - the waist.

Quetelet index

In the middle of the 19th century, the statistician and sociologist Adolphe Quetelet created a formula by which one can determine the excess weight of a person. The Quetelet Index (BMI) is a correspondence between human height and weight, which helps to determine the amount of excess or missing weight.

To calculate the body mass index, you must divide your weight by (height in meters * height in meters). It looks like this - weight kg: (height in m) 2.

Example: 74 kg: (1.76 * 1.76) = 23.88 - the resulting figure is the Quetelet formula or body mass index.

Quetelet mass index degrees

The mass index must be used with care. When calculating it, the amount of fat in the body of a given person is not taken into account. Therefore, this weight analysis is indicative only.

1. Index up to 18.5 - lack of weight. There is no risk of obesity. Women may experience hormonal disorders, miscarriages, hypotension, and decreased hemoglobin.
2. Index 18.6 - 25 - normal weight. No risk of disease. There is no need to reduce or increase weight. Weight changes can only be personal preference.
3. Index 25.1 - 30 - extra kg... There is a risk of gradual occurrence of hypertension, varicose veins, diabetes mellitus.
4. Index 30.1 - 35 - 1 degree of obesity. This disease is not only a lot of fat on the human body or a cosmetic defect. Starting with this degree of obesity, the cardiovascular system and cerebral vessels bear a double load. Sugar is not properly absorbed by the body, which leads to diabetes.
5. Index 31.1 - 40 - 2 degree of obesity. The need for urgent action is doubled. Arthrosis, arthritis, hypertension, strokes, heart attacks are the consequences of this disease.
6. Over 40.1 - 3 degree of obesity. The huge possibility of dying from all of the above diseases increases significantly. There is an urgent need to take measures to reduce excess weight.

Volumes

The height-to-weight ratio or Quetelet index is not an ideal indicator of a beautiful body in girls or the absence of health problems.

To BMI, you must add a measurement of the waist. This parameter will be in addition to the Quetelet formula.

1. The centimeter tape showed more than 80 cm - there is a small probability of developing metabolic diseases.
2. Measurements with a centimeter tape showed a waist volume exceeding 87 cm - a critical figure. There is a need to reduce weight due to possible health complications.

Broca's formula

In the 19th century, the French surgeon Paul Brock developed a calculation by which you can determine the optimal weight indicator for a person. This calculation formula includes the need to know your height in cm from which you need to subtract one hundred. The resulting figure will be an indication of the ideal weight.

But for the correct calculation there is a need to know your body type. So, girls with the same body weight may look different, due to different body types.

• Asthenics - (measured in cm. Height - one hundred) - 1/10 of the result.
• Normostenics - measured in cm. Height - one hundred.
• Endomorphs - (measured in cm. Height - one hundred) +1/10 of the result.

Negler's formula

In the calculation, a certain height and weight are used. To the ideal 152.4 cm (this figure is considered ideal) - (to the next 2.5 cm), add 0.9 kg of weight. Add 10% of the result to the output figure.

For example: original height 165 cm. 165-152.4 = 12.6: 2.5 = 5.04 * 0.9 = 4.536. The resulting figure must be added to the ideal 45 kg = 49.536. And add 10%. As a result, we get 54.48 kg.

Neger's formula is not suitable for all body types. From a girl with a tall stature, you can make an "anarex".

John McCallum's Formula

The body mass formula was developed by John McCallum, a sports expert and writer. This formula is recognized as the best among athletes. It should be determined by the volume of the wrist.

McCallum body parameters:

• the volume of the chest is 6.5 * per carpal volume;
• waist volume - measured chest volume * 0.53;
• hip volume - measured chest volume * 0.85;
• thigh (leg) volume - measured chest volume * 0.53;
• neck volume - measured chest volume * 0.37;
• biceps volume - measured chest volume * 0.36;
• leg volume - measured chest volume * 0.34;
• forearm volume - measured chest volume * 0.29.

Lorentz formula

At the beginning of the 20th century, a Dutch physicist calculated the perfect weight for a person. It is based on growth.

This calculation is suitable for people over 20 years old. Growth has no restrictions.

Formula for the fair half: (subtract 100 from the height measured in cm) - (in cm measured height-150) divided by 2.

Example: 175cm = (175-100) - (175-150) / 2 = 75-25 / 2 = 62.5 kg

Breitman's formula

To determine the ideal weight for a particular person using the Breitman formula, it is necessary to use the growth parameter in cm. The calculation is made according to the formula:

Measured growth parameter in cm * by 0.7 and subtract 50.

Example: 176 cm * 0.7-50 = 73.2 kg.

The calculation of the perfect weight according to this formula is more suitable for women of more mature age.

The role of age in the ratio of height and weight

Over time, the human body undergoes changes. The muscle volume decreases, the body fat increases. Due to hormonal age-related changes in women, there is a redistribution, or even an excessive accumulation of subcutaneous fat. Therefore, there is a need to compare your weight not with youthful indicators, but taking into account age.

The famous surgeon Brox made his own BMI calculation, laying it down the number of years and features of the figure.

1. The best result for women under 39 years of age. Height measured in cm - factor 110.
2. The best female weight 40+. Height, measured in cm - 100.
3. For asthenic physique, it is necessary to subtract 10% of the ideal weight.
4. For female endomorphs, it is necessary to add 10% of their ideal weight.

Calculation of the ratio of height and weight, based on the type of female figure

Having the perfect physique is the dream of any woman or girl. All people are different and this should be recognized. Every woman is unique, no matter what body proportions she has.

1. A - shaped body type. The representatives of this figure have noticeably narrower shoulders than the hips. The waist is at least 20 cm less than the hips. Representatives of the A-shaped body type can be of different heights.
2. X - shaped type of figure. In this case, the shoulders and hips have approximately the same volume. This body type has smooth transition lines between the hip, waist and chest.
3. H - shaped body type. The shoulders and hips are the same volume. The waist practically does not stand out. The thighs have no "feminine" curves.
4. T - shaped physique. "Boyish" body type. The shoulders are wider than the hips. The legs are long and thin. The width of the hips is no more than 20 cm larger than the waist.
5. O - shaped physique. In a female figure of this type of this type, the most prominent part of the body is the waist. Sufficiently slender hips and shoulders, but a huge belly.

Weight and height norm: table for women

The numbers in this table show the average allowable weight of a woman at different ages.

Using a dedicated calculator

On the Internet, different types of online calculators have found their place, which can be used to calculate the optimal body weight according to different formulas. The way to use the online calculator is very simple. You need to know the parameters of your body and enter data into the calculator windows.

To find out your values ​​using the Quetelet formula, you only need to know your body height and weight. The online assistant will make the calculation itself.

Height-to-weight ratio in a teenage girl

The formula will help you find out the child's BMI. Children's calculation of the Quetelet index = child's weight in kg / per height in m²... For example: a child's height is 1.35, weight is 35 kg = 35 / 1.82 = 19.23. This is the norm for children 12-13 years old.

To determine the BMI of a teenager, you need to do the same calculation as for babies. The Quetelet index for adults is not yet suitable for them, due to the constant growth of the body.

It is necessary to calculate the indicator - percentile.Percentile = teen weight / height. The result obtained must be compared with the values ​​that correspond to the age of the young man.

Indicators:

• The result is 95 or more - obesity disease.
• Result 80 - 95 - overweight.
• Result from 6 - 80 - normal weight.
• Less than 6 - lack of weight.

Body mass index during pregnancy

BMI during pregnancy is estimated according to the generally accepted Quetelet calculations. But this formula has its own characteristics. To apply this calculation, you need to know the number of weeks of pregnancy, weight and height before pregnancy.

Formula: weight before pregnancy / height squared:

• the result is 19.8 and less - underweight;
• result up to 26 - normal weight;
• anything over 26 is overweight.

During pregnancy, there is a need to monitor your weight. Any changes in the mother's weight can affect the development of the child.

Why you need to know your BMI

The Quetelet index or formula is a relative indicator. But it is necessary to know it and not even for the beauty of the body. Some of the health is hidden in these numbers. Indicators that exceed the norm should be alarming.

Behind them are such serious diseases as varicose veins, arthrosis, thrombophlebitis, strokes, heart attacks, diabetes. Few people want to have so many problems in their body.Therefore, it becomes necessary to monitor your BMI in order to prevent excess weight with its consequences.

Disadvantages and limitations of using the BMI method

The Quetelet formula has its drawbacks. These include:

• the calculations do not take into account age;
• well-developed musculature can be interpreted as a threat to overweight or obesity;
• there is no difference between female and male sex.

These are both disadvantages and limitations. If you need in-depth calculations, you should take several different formulas.

How to normalize your body mass index

For girls looking to lose weight or gain weight, calculating body mass index can be an assistant. You need to know certain rules. They are very similar for both groups.

1. Fractional meals - 3 main meals and 2 snacks (both for those who are losing weight and for those who want to get better).
2. Calorie count. Those wishing to lose weight - cut in accordance with the norms. For those who are gaining weight, the calorie content of food must be increased due to complex carbohydrates and protein.
3. Exercise improves metabolism.
4. It is necessary to check the body for chronic diseases.
5. Eliminate bad habits.
6. Adequate sleep. Internal organs work better. The body absorbs everything it needs and removes toxins.

The body mass index in girls, or in another way, the ratio of their height and weight, can be an assistant in solving health problems. And also be a guide in achieving the desired proportions of the figure.
