This calculator estimates the weight and height of a child according to their age to the nearest day. In contrast, this calculator provides a comprehensive weight estimate in strict accordance with the height and age of the child.

The value ranges, methodologies, and recommendations are based on guidelines developed by the World Health Organization (WHO), which has conducted extensive research on the development of healthy children of different nationalities and geographic areas.

Please remember that our calculator generates results based solely on the data you have provided. If you made measurements with a large error, then the result will be inaccurate. This is especially true for measuring height (or body length).

If our calculator shows you the presence of any problem, then do not rush to panic: measure the height again, and let the measurements take two different people in turn and independently of each other.

Height or body length

In babies up to two years old, it is customary to measure the length of the body in a lying position, and from two years old, they measure growth, respectively, in a standing position. The difference between height and body length can be up to 1 cm, which can affect the results of the assessment. Therefore, if for a child under 2 years old you indicate height, instead of body length (or vice versa), then the value is automatically converted to the value required for correct calculation.

What is the height (body length)

Growth is the most important indicator that should be monitored monthly (see). Obtaining ratings "undersized" and "very undersized" may be a consequence of prematurity, illness, developmental delay.

High stature is rarely a problem, but a score of "extremely high" may indicate the presence of an endocrine disorder: such a suspicion should arise if a very tall child has both parents of normal average height.

Very short Severe growth retardation. It can also lead to excess weight. The participation of a specialist is required to identify and eliminate the cause of the lag. Undersized Growth retardation. It can also lead to excess weight. Consultation of a specialist is required. Below the average Short child, growth within normal limits. Average This growth is in most healthy children. Above the average Tall child, growth within normal limits. High Such a big increase is not common, however, it does not indicate the presence of any problems, therefore it is considered the norm. Usually this growth is hereditary. Very tall Overgrowth in a child is usually hereditary and is not a problem in and of itself. However, in some cases, such growth may be a sign of endocrine disease. Therefore, exclude the possibility of an endocrine disorder by consulting a specialist. Height does not match age You may have been wrong about the height or age of the child.
If the growth of the baby is really the same as you indicated, then there is a significant deviation from the norm, which deserves the special attention of an experienced specialist.

How weight matches height

The ratio of height and weight gives the most meaningful idea of ​​the harmony of a child's development, it is expressed as a number and is called the Body Mass Index, or BMI for short. This value is used to objectively determine the problems associated with weight, if any. And if there are none, then they are convinced that the BMI indicator is normal.

Please note that normal body mass index values ​​for children are radically different from those for adults and are very dependent on the age of the child (see). Naturally, our calculator estimates BMI in strict accordance with the age of the child.

Severe underweight (severe wasting) Severe underweight. Great emaciation. Necessary nutritional correction and treatment as prescribed by a doctor. Underweight (underweight) Deficiency of body weight. Underweight for specified height. Correction of nutrition is recommended according to the doctor's prescription. Reduced weight Weight is within normal limits. The child is less well-fed than most of his peers. Norm Ideal weight-to-height ratio. Being overweight (risk of being overweight) The child's weight is normal, but there is a risk of being overweight.
In this case, it is shown to pay attention to the weight of the child's parents, because the presence of obesity in a parent significantly increases the child's risk of overweight.
In particular, if one of the parents is obese, then there is a 40% chance the child will gain overweight. If both parents are obese, then the probability of overweight in a child increases to 70%. Overweight Correction of nutrition is recommended according to the doctor's prescription. Obesity Necessary nutritional correction and treatment as prescribed by a doctor. Obesity: A nutritional correction is required as prescribed by a doctor. Impossible to assess You may have been wrong about the height, weight, or age of the child.
If all the data are indicated correctly, then there is a significant deviation of the indicators from the norm, which requires the special attention of an experienced doctor.

What is the weight

A simple estimate of weight (based on age) usually gives only a superficial indication of a child's developmental pattern. However, getting "Low Weight" or "Extremely Low Weight" grades is a good reason to consult a specialist (see). Full list possible weight estimates are given below:

Strong underweight, extremely low weight The child is probably emaciated. It is necessary to consult a specialist. Underweight, low weight The child is probably emaciated. It is necessary to consult a specialist. Less than average Weight is below average, but within the normal range for the indicated age. Average Most healthy children have this weight. Greater than average In this case, compliance with the norm should be assessed by body mass index (BMI). Very big In this case, weight is estimated by body mass index (BMI). Weight does not match age You may have been wrong about the weight or age of the child.
If all the data is correct, then the baby may have problems with development, weight or height. See height and BMI estimates for details. And be sure to consult an experienced specialist.

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 of 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

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:

1. obesity requiring treatment;
2. overweight;
3. slightly increased weight, which is within the permissible range of fluctuations in the norm;
4. normal weight (see also:);
5. underweight;
6. emaciation requiring treatment.

Features of the first year of a baby's life

Dear reader!

This article talks about typical ways of solving your questions, but each case is unique! If you want to know how to solve your particular problem - ask your question. It's fast and free!

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 WHO guidelines, a child who is on breastfeeding and having a birth weight of 3.3 kg (boy) or 3.2 kg (girl). 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 lower body weight and height (this is often the case in children born ahead of time, as well as for those who are born of undersized parents), then there is no need to worry about the fact that after a month or two he "lags" behind the table 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, it is necessary 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. At 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 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

The average weight of a harmoniously developed 4-year-old baby, according to WHO, 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 recover by 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.

You also need to take into account that girls grow intensively after 10 and up to 12 years old, 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 disadvantage necessary elements 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 different short stature and asthenic physique, then, with a high degree of probability, the indicators of the child's body weight and height will be similar.

Also, factors affecting weight and height in children include the following:

1. sleep and rest mode (it is required that the total daily sleep duration is appropriate for age);
2. active or passive lifestyle - in active babies, weight and height differ in their proportionality;
3. diet - for harmonious development, it must include all the necessary vitamins, micro and macro elements, be varied;
4. diseases of an infectious origin that the child suffered;
5. the fact of the presence of genetic pathologies;
6. features of the course of pregnancy in the mother;
7. features of the delivery process.

Deviations from the norm

A significant underweight or, on the contrary, overweight, as well as too slow / very intense growth is a consequence of the influence of various factors. To identify the causes of serious deviations, you will need to seek advice from narrow specialists - a genetics, endocrinologist, neuropathologist or gastroenterologist.

What a variety of children's shops nowadays: at every step on the street and in the Internet! The eye rejoices and is lost in this abundance. Many parents at least once, but bought baby clothes not in size. Well, if the thing turned out to be large, but if it is small? To avoid such disappointment, you should be well-versed in two things. The first is the body parameters of the child that you measured correctly. And the second is the correct determination of the current size of clothing, and depending on the manufacturer. So, let's start our "excursion" with initial preparation - measurements of the child's parameters.

Will it or won't it? This question worries all mothers when buying clothes for children.

1. The main indicator for most manufacturers is growth. To measure it accurately, place your barefoot child against a flat, vertical surface, such as a wall. At the level of the top of the head, make a mark, and then measure the line on the wall with a centimeter or ruler. With age, children show individual characteristics of the structure of the body. Someone is fuller, someone is thinner. Someone has longer legs, someone shorter. One baby has a wide chest, and the other is the other way around, so it is important to determine at least 5 more parameters, in addition to growth (there are more than 10 of them in general).
2. To measure the circumference of your chest, slide a centimeter under your arms through your ribcage and shoulder blades (we recommend reading :).
3. When measuring the waist, it must not be pulled tight, the tape must remain free.
4. When measuring a child's thighs, the tape should go over the buttocks.
5. To measure the length of the sleeve, first bend the child's arm a little and only then take the measurement: from the shoulder joint to the wrist joint.
6. To measure the length of your pants, run the tape from the waist to the ankle along the side seam trousers.

For children under 3 (maximum, 5) years old, the main parameters will be age and height. But than older child, the more important it is to determine baby size clothing other metric indicators: chest, hips, waist, etc.

Most likely, over time, you will find your favorite manufacturers, whose clothes not only look great on their own, but also fit your child perfectly. What manufacturers can you find on the Russian market? How to determine the size of children's clothing? Let's sort it out one by one, including with the help of our tables with the sizes of children's clothes. Let's start with our domestic production, and then we'll talk about foreign manufacturers from Europe, the USA and China.

For kids younger age it is important to know only height and age, the rest of the measurements are needed already at an older age

Children's clothing from Russia

Domestic manufacturers are obliged to sew things in accordance with GOST. It is important to find honest manufacturers who really comply with the standards and carry out tailoring according to the declared Russian sizes. With such a manufacturer, you will not have any hassle. In fact, this is the only thing that matters when buying domestic items. Find the match between your child's parameters and size according to the table below and go for a good shopping!

Parents of newborn babies, pay attention, the most intensive growth is in small children under 1 year old! In 12 months they will change 5 sizes on the Russian scale, i.e. will grow by 3, 5, 7, or even more centimeters.

Sizes of children's clothing from Europe and the USA

Buying foreign things is associated with additional risks - you need not be mistaken with unfamiliar sizes. How to figure it out? As always, we are helped by a table of sizes of children's clothes, but now with a foreign gradation. Please note that some manufacturers sew things in such a way that the folded pants and sleeves look great. In this case, you can choose things to grow. Very cool, right? Children grow up so fast!

If the pants are a little too big, you can fold them

Sizes of children's clothing from China

It will not be superfluous to understand the peculiarities of Chinese things - after all, we have a lot of it in Russia! The main difference is that our manufacturers are guided mainly by height, while Chinese ones are guided by age.

On things from China for children who have come out of infancy, there are markings with the letter "T". For example, 9 T or 10 T. "T" means the number of years, ie. 9 T - things for a 9-year-old, 10 T - for a 10-year-old, etc. It is also important that the domestic size range is wider than the Chinese one. For example, for babies up to a year in China there are 4 sizes, and we have as many as 6.

Chinese sizes differ significantly from Russian sizes, so you need to carefully choose things

Finally, briefly about the important things in our journey

Choosing clothes for a child is not an easy task, which can be dealt with using size charts.

1. Children with the same height can vary greatly in other parameters. Use children's clothing size charts - then you can't go wrong.
2. Foreign manufacturers often take into account not only volumes, but also the sex of the child. For example, for 5-year-olds, there will be separate grades for girls and boys.
3. Some manufacturers have peculiarities in the length of the product, the girth of the waist or chest, then they indicate their own size grids.
4. In Europe and Russia, manufacturers are primarily focused on growth. At the same time, things from Europe are designed for fuller children, and Russians - for thinner ones.
5. If you buy a French product, take more of it, because their things are mostly small.
6. With German and Italian things, it is just the opposite: after the purchase, they remain for some time to grow.
7. In China, things are a little more complicated. They can measure more and less. You should only trust children's clothing sizes from "Factory China".
8. If the baby is less than 3 years old, dressing him is sometimes not so easy, so look for comfortable and simple fasteners. It makes sense to turn Special attention and on the material: natural - more preferable for the delicate skin of the baby. After 5 years, you can safely buy things with intricate clasps.
9. It is worth washing new items, even if they have been sealed. However, keep in mind that natural fabrics in hot water they sit down strongly.

One of the indicators of the normal development of each child is the correct ratio of height and weight, appropriate for age. Many parents are worried looking at their sons: it seems that he was born large, but to school age became disproportionately thin and long. Do not worry too early: to determine whether this is a variant of the norm, the table of the height and weight of boys by years will help.

Physical development of boys

The data for the height and weight of boys according to the WHO tables were updated in 2006 and are relevant to this day. In addition to the ratio of body length and its mass, parameters such as the circumference of the head and chest of children are also important for WHO: these indicators provide additional confirmation that the boy is developing normally. It is especially important to measure the circumference up to a year by months: at each appointment, the pediatrician must, in addition to putting the child on the scales and height meter, measure the head and chest with a measuring tape. Russian data slightly differ from the WHO data, they are an average value.

The average height and weight of boys under 18 can be checked in the tables:

Is the boy developing harmoniously?

Boys grow up to 22 on average. At the same time, the average height of the male population of Russia is 178 cm. The increase in the height and weight of boys is especially intense in the first year after birth and during puberty (from 11 to 18 years). On average, during this time, the weight of the guys increases by 35 kg, and their height - by 35 cm.
How proportional is the ratio of height and weight, you can find out using the centile table. The columns indicate the quantitative boundaries of the growth and weight indicators for a certain percentage of boys; an interval of 25% -75% is taken as averages. If the boy's indicators are included in these corridors, then this is the norm. Columns before and after these intervals are indicators below (10% -25%) and above (75% -90%) of the norm. If the boy's height and weight are in the extreme corridors, this is a reason to see a doctor. It is very important that both height and weight are in the same corridor (+/- one column).

It's easy to use:

• In the table "Height" in the left column we find the age of the boy, and horizontally from this number - the height.
• In the same way, we determine the boy's weight according to the "Weight" table.

Rate ratio the age, height and weight of the boy you can use the following tables:

Boy's height, cm

Boy's weight, kg

The main factors that affect the height and weight of boys are:

• good nutrition;
• night sleep of sufficient duration;
• regular sports and physical education;
• genetic predisposition.

You should not try to correct the height and weight of boys with surgery or hormonal drugs - this can seriously affect your health. If these parameters do not correspond to the norms, but at the same time pathologies are not diagnosed, perhaps it is worth looking at it from the positive side? A unique child is growing in your family, which, in addition to physiological characteristics, will certainly show other abilities and talents!

The car is potentially dangerous for the people around it, and if its driver is drunk, then the threat becomes very obvious. According to the traffic police, in Russia in every eighth road traffic accident a driver who was intoxicated is to blame. Tens of thousands of people die in "drunken" road accidents every year - and these statistics cannot be ignored.
