Height-to-weight ratio in children and adolescents. What should be the normal height and weight for girls? What is your height at 13 14 years old


A routine examination of a child always involves weighing and measuring height. Why is this necessary? The obtained figures are checked against a table of height and weight of boys by age, which helps to determine whether development is harmonious, whether it is age appropriate, and to identify possible diseases.

Excessive weight or underweight, for example, can tell the pediatrician about a violation in the feeding regime and become a reason to introduce complementary foods.

Some parents worry about their sons' height or weight. To be calm and always keep your finger on the pulse, we bring to your attention tables of height and weight norms for boys. Save them and you will be able to recognize signs of any developmental disorders at the very beginning and without the participation of doctors.


Weight and height of boys by month: table

Pay attention to the columns of 3% and 97% - their values ​​indicate a possible developmental disorder and can be signals of various diseases. Be sure to consult a pediatrician for additional diagnosis.

Columns 10%, 25%, as well as 75% and 90% - often do not indicate the presence of any pathology, but may be a hereditary feature.

The average figure of 50% is the reference norm for height and weight.

Do not forget that the height and weight of boys by year in the table are averaged. Small deviations in any direction are considered acceptable. The main thing is not to panic if your baby is ahead in development or, on the contrary, is a little behind.

The first year of life is the period of the most intensive growth of children. Its dynamics are spasmodic: the first three months are the most intense growth - on average 3.5 cm per month, then from the 6th to the 9th month of life the baby adds about another 1.5-2 cm, and from the 9th month of the year - 1 cm.

Boys weight chart

Weight is the most unstable indicator and can change for a number of different reasons. It depends on diet, sleep, previous diseases, and heredity. For example, it has been proven that artificial feeding significantly increases weight.

If you are overweight or underweight, the main thing is to find the cause. In this case, it will be possible to take action and the child’s body will quickly recover.

What can influence the development process of a child?

Many parents turn with concern to the height and weight chart of boys, especially newborns. They are primarily concerned about whether their child is developing according to his age. However, a deviation from the norm is not always a manifestation of some kind of malfunction in the body. There are a number of main factors influencing the overall development of the body:

  • Full sleep
  • Nutrition - the child must receive all the necessary substances from food, as well as proteins, fats and carbohydrates in sufficient quantities
  • Genetic predisposition
  • Psychological situation
  • Nationality
  • Hormones

Most parents are interested in the physical health of their children. The weight and height of a child under 10 years of age are his key parameters for both girls and boys. The evaluation criterion is a special scale or auxiliary tables compiled by the World Health Organization. What values ​​will be optimal for different ages of both sexes?

Measuring a child’s physical appearance provides insight into the progress of development.

Development indicators for girls and boys in the first year of life

Weight by month

There is a separate table showing weight gain for babies up to one year:

Norm and limits of deviation of a child’s weight in the first year of life

Height and weight of a child from one year to 10 years

Very low and high numbers indicate the presence of deviations; those that are above and below the average are considered variants of the norm.

The height and weight table for children under 10 years of age is compiled separately for boys and separately for girls and will help you independently determine whether the process of your child’s physical development needs to be adjusted.

Indicator table for boys

Taking into account the regular weight and height gain of young men, WHO has compiled the following table of height and weight of boys under 10 years of age:

Growth indicators of development of boys under ten years of age

Weight development indicators for boys under ten years of age

The height and weight table for boys aged 10 years shows the proportional ratio for a given time period:

Indicator table for girls

Unlike boys, girls develop much faster. Therefore, it should not be surprising that children of different sexes of the same age may be inferior in performance to each other. The height and weight of girls under 10 years old is presented in this diagram:

Features of development of children from 3 to 5 years old

The physical development of a 3-5 year old child is determined by several parameters:

  1. 3 years - height 96 cm+\- 4 cm, weight 12 kg +\-1 kg, chest girth 51 cm+\-2 cm, head circumference 48 cm, presence of about 20 baby teeth;
  2. 4-5 years - 104 cm+\-4 cm, 17 kg+\-1 kg, chest 55 cm+\-2 cm, head 50 cm, teeth have not yet been replaced with permanent ones;
  3. the skull of a three-year-old child is equal to 80% of the volume of an adult’s skull, the spine is unstable, and bones and joints are easily deformed from negative external influences;
  4. very rapid blood circulation corresponds to a pressure of 95 to 58, increased excitability is observed, leading to rapid fatigue.

How do girls and boys grow from 5 to 10 years old?

Starting from the age of 5, the child’s body gradually transforms into a teenage one. The height and weight standards for children aged 10 years, as well as during the primary school period, are:

  • 6 years - the body becomes 6-7 cm taller and 2.5-3 kg heavier, average height is 107-121 cm, weight 18-28 kg, chest girth 56-65 cm;
  • 7 years - another 8-10 cm are added in height, 2.5-3 cm to the chest, body length is 114-128 cm, the baby weighs 20-30 kg;
  • 8 years - changes characteristic of puberty are not yet noticeable, 21-32 kg and 119-134 cm;
  • 9 years - children grow to 125-140 cm and 24-36 kg, respectively;
  • 10 years - averages - 129-146 cm and 25-39 kg.

For a simpler understanding of child development, here is a table of the height and weight of children 10 years old:

Immediately after the birth of the baby, the doctor informs the happy parents such parameters as the weight and height of the child. In the future, mom and dad will have to carefully monitor the baby's weight gain and height. But why is this so important and what do these parameters depend on?

Child height and weight indicators

There are several factors that influence the rate of weight gain and growth. These are heredity, nutrition and its quality, as well as living conditions. If we talk about height, then genes have the greatest influence - when both parents are tall, then their child will also grow faster. But weight is affected by the quality and quantity of food. If you follow the rules and provide high-quality complementary foods, then there will be no problems with weight gain.

Living conditions are of particular importance. This means that you need to ensure an optimal lifestyle, walk with your child in the fresh air, especially in the sun, as it promotes the production of vitamin D. You need to monitor the health and condition of the baby, then he will grow within normal limits.

Tables: height and weight norms according to WHO

Below you will find detailed information about the average performance of newborn boys and girls up to one year. The only thing that needs to be noted is that the parameters are approximate, since each child’s body is individual.

Age, monthsWeight, kgWeight gain, gHeight, cmHeight gain, cm

11 9,5-10,0 400 72-78 1,5
12 10,0-10,8 350 74-80 1,5

Approximate weight and height gain by month:

As can be seen from the table, in the first year of their life, babies gain approximately seven kilograms of weight and grow up to thirty centimeters. The increase in height and weight is quite active.

Let's take a closer look at the increase by month:

  1. The first month from birth is characterized by an average increase of 600 grams and from two and a half to three centimeters. The head circumference becomes more rounded, on average this figure increases by one and a half centimeters.
  2. The second month of life will bring a weight gain of about 700-800 g, and about 3 cm in height. The head circumference increases again - about one and a half centimeters.
  3. The third is distinguished by an increase of 800 and two and a half centimeters, the head circumference increases again - by one and a half centimeters.
  4. The fourth – up to 750 grams and 2.5 cm.
  5. Fifth - plus another seven hundred grams and two and a half centimeters in height.
  6. Six months – another six hundred grams and two centimeters. Pay attention to the ratio of the width of the shoulders to the length of the baby’s entire body; normally it is 1:4. The head circumference is necessarily less than the chest circumference.
  7. The seventh month is about 600 g, and two centimeters of growth.
  8. Eighth - on average 550 grams of increase and 2 cm in height. As you can see, the weight gain is gradually declining.
  9. Ninth – the baby is another 500 g heavier and 2 cm taller.
  10. The tenth child is 450 grams heavier and one and a half to two centimeters taller.
  11. Eleventh - plus four hundred grams and one and a half centimeters.
  12. A year is another plus three hundred and fifty grams and one and a half centimeters.

WHO height and weight chart for girls under 1 year of age

The rate of development of newborn boys and girls is slightly different. We suggest you familiarize yourself with how much girls gain in weight and height. Remember, these are approximate figures.

Average normal value for baby girls:

Age, monthsWeight, kgHeight, cm
0 2,8-3,7 47,3-51
1 3,6-4,8 51,7-55,6
2 4,5-5,8 55-59,1
3 5,2-6,6 57,7-61,9
4 5,7-7,3 59,9-64,3
5 6,1-7,8 61,8-66,2
6 6,5-8,2 63,5-68
7 6,8-8,6 65-69,6
8 7,0-9,0 66,4-71,1
9 7,3-9,3 67,7-72,6
10 7,5-9,6 69-73,9
11 7,7-9,9 70,3-75,3
12 7,9-10,1 71,4-76,6

Usually, at the end of the year, babies become longer, up to 25 cm, and heavier, up to six kilograms.

WHO table: height and weight for boys under 1 year

It can be seen that the indicators differ from those of girls, but not by much. Check out the average below.

Average normal value for male infants:

Age, monthsWeight, kgHeight, cm
0 2,9-3,9 48-51,8
1 3,9-5,1 52,8-56,7
2 4,9-6,3 56,4-60,4
3 5,7-7,2 59,4-63,5
4 6,2-7,8 61,8-66
5 6,7-8,4 63,8-68
6 7,1-8,8 65,5-69,8
7 7,4-9,2 67-71,3
8 7,7-9,6 68,4-72,8
9 8-9,9 69,7-74,2
10 8,2-10,2 71-75,6
11 8,4-10,5 72,2-76,9
12 8,6-10,8 73,4-78,1

Boys become approximately 25-26 centimeters taller and seven kilograms heavier.

Height and weight chart for girls from 1 to 10 years old

The height and weight of both male and female infants slows down after reaching the age of one year, so these parameters are then measured by year.

Let's look at the weight of babies by year:

Age in yearsShortBelow the averageAverageAbove averageHighVery tall
1 7 7,9 8,9 10,1 11,5 13,1
2 9 10,2 11,5 13 14,8 17

4 12,3 14 16,1 18,5 21,5 25,2
5 13,7 15,8 18,2 21,2 24,9 29,5
6 15,3 17,5 20,2 23,5 27,8 33,4
7 16,8 19,3 22,4 26,3 31,4 38,3
8 18,6 21,4 25 29,7 35,8 44,1
9 20,8 24 28,2 33,6 41 51,1
10 23,3 27 31,9 38,2 46,9 59,2

As you can see, there are indicators from low (below normal) to too high (above normal). For example, it is normal for a ten-year-old girl to weigh almost 32 kg, but there is a problem if the reading on the scale exceeds 46 kg.

There is also a table indicating the height of girls:

Age in yearsShortBelow the averageAverageAbove averageHighVery tall
1 68,9 71,4 74 76,6 79,2 81,7
2 80 83,2 86,4 89,6 92,9 96,1
3 87,4 91,2 95,1 98,9 102,7 106
4 94,1 98,4 109,4 107 111,3 115,7
5 99,9 104,7 102,7 114,2 118,9 123,7
6 104,9 110 115,1 120,2 105,4 130,5
7 109,9 115,3 120,8 126,3 131,7 137,2
8 115 120,8 126,6 132,4 138,2 143,9
9 120,3 126,4 132,5 138,6 144,7 150,8
10 125,8 132,2 138,6 145 151,4 157,8

It can be seen that the normal height of a ten-year-old girl is about 139 centimeters, and the highest figure is when the height is above 157. But this parameter is largely influenced by genetics. If mom and dad or one of the parents is tall, or, conversely, short, then the child will be the same. Although it is not impossible for short parents to grow up to have tall children.

Height and weight chart for boys from 1 to 10 years old

So far, boys' figures are not very different from girls' weight and height. Over time, the difference will increase.

Let's look at the weight of guys from one to ten years old:

10 23,2 26,7 31,2 37 45 56,4

The growth chart for boys from one year to their first anniversary – ten years – is also interesting:

10 125 131,4 137,8 144,2 150,5 156,9

It is advisable not to measure too often at this stage of life, it is of no benefit. If it is still desirable to monitor your weight in order to prevent problems with obesity, then it makes sense to measure height once every three months until two or three years, and once a year in subsequent years.

Height and weight chart for teenage girls

Teenagers no longer require frequent measurements; it is enough to take them once a year. However, you can control your weight more often if you observe a clear deficiency or excess of this indicator.

The weight norm for girls under 17 years of age is indicated in this table:

It is worth remembering that both weight and height can be inherited, so these figures are only approximate.

Height and weight chart for teenage boys

Surprisingly, from ten to fourteen years old, girls outstrip boys in height. This is due to the fact that hormonal changes in the body have not yet begun in boys. But upon reaching the age of fourteen, they begin to grow more actively, completely overtaking girls.

The weight of boys under 17 years old is indicated in the table:

AgeVery lowShortBelow the averageAverageAbove averageHighVery tall

If there is a genetic predisposition to tall height, that is, if dad is tall, then it is normal to be 180 centimeters tall at the age of fourteen. In this case, look at the maximum, not the average.

Features of height and weight gain in premature infants

In case of premature birth, the baby will gain weight differently. Everything will depend on the so-called gestational age - the week when the baby was born. Typically, the rate of weight gain and growth is different for each case.

Let's find out how premature babies gain weight before the first half of the year:

  1. If the baby was born weighing up to a kilogram, then he will gain approximately 600 g.
  2. If from a kilogram to one and a half - about 740-750.
  3. From one and a half to two and a half kilograms - approximately 870.

And the second half of the year:

  1. If the birth weight was up to 1 kg, then the child will gain approximately 800 g.
  2. Larger newborns – 600 g.

During the first year of life, premature babies grow from 25 to 36 centimeters. Already in the second or third year of life they catch up with their peers.

Concomitant diseases and physical development

If a newborn suffers from any disease, then he will gain more slowly in height and weight. Opposite cases are also possible - when, due to illness, a child gains more height than normal.

There are several common diseases:

  1. Cardiovascular - congenital heart disease and circulatory disorders cause the heart to not work well enough. As a result, the organs do not receive the necessary nutrients, physical development is delayed and a lack of weight and height occurs.
  2. Bronchopulmonary is bronchopulmonary dysplasia (BPD), a malformation of the trachea, bronchi, and lungs. They have a negative effect on blood circulation, which means that nutrients and oxygen reach the organs in small quantities, which delays the baby’s development.
  3. Diseases of the gastrointestinal tract - problems with the intestines, esophagus, liver, bile ducts. They can only be resolved surgically in the early stages after birth. They also negatively affect height and weight gain.
  4. Diseases of the endocrine system - hypothyroidism from birth causes too much weight gain due to the accumulation of excess fluid in the body and the occurrence of edema of the subcutaneous fat.

In order not to rack your brains over whether your child is growing normally or whether he has any diseases, visit your pediatrician every month. A professional will have time to notice any deviations from the norm.

The influence of the type of feeding on the weight gain of the newborn

Previously, it was believed that only one type of feeding influenced weight gain - artificial feeding (feeding infant formula). But now there are cases where a mother overfeeds her baby with breast milk.

The way you feed your baby affects weight gain and growth rate

In both types of feeding, the child may gain weight too rapidly, while growing tall like a normal child. If your child grows one and a half centimeters longer every month up to a year, but at the same time becomes heavier by more than a kilogram, you are probably overfeeding him.

Moderation is important - excess weight causes problems such as delayed motor development and skills. It is more difficult for the baby to roll over, the skill of raising his head is poorly developed, etc. All this is hampered by excess body weight.

A newborn weighs little - is there any reason to worry?

It is body weight that determines the ability to adapt to the outside world. If the toddler was born with a weight within the normal range, then development will occur without problems or delays. If the baby is premature, then his body weight will lag behind the body weight of his peers, although over time he will catch up with them. But what to do with a child who is low weight so that adaptation to the outside world occurs without problems?

  • Stay warm. Children with low weight have a very thin layer of subcutaneous fat. This prevents them from retaining heat. Monitor your baby's temperature to prevent hypothermia. Measure the temperature every six hours - below 36.5, which means you need to warm it up. It is correct not to cover it with a blanket, but to ensure skin-to-skin contact - when the mother places the baby on her chest.
  • Feed by the hour. This is necessary, otherwise the baby’s blood glucose will drop, and he will sleep poorly and feel worse. The first days - sixty milliliters of milk per day, then plus 20 ml of milk every day. You need to stop when you reach 200 ml per kg. Meals should be frequent - 8-10 times.
  • Massage for appetite – 2.5 kg, and doctors approve of massage, some procedures need to be carried out for general strengthening. Massage helps you gain weight as it improves your appetite. It is carried out only after meals - an hour later. It is advisable to use the services of a professional children's massage therapist, or parents can master the technique themselves. Having lubricated your hands with baby cream, you need to gently massage the child’s muscles from top to bottom - from the neck, then the back, buttocks, legs, then massage the arms and chest.

In conclusion, we can say that if experts have ruled out the possibility of congenital diseases, and the baby weighs less only because of prematurity, then there is no particular reason to worry. Over time, he will catch up with his peers in development. To make this happen, follow the recommendations - do not give the baby the opportunity to become hypothermic, feed him carefully and massage him when the pediatrician allows.

Tables of normal height and weight of children for boys and girls up to one year old by month, from one year to 10 years, from 11 to 17 years old by year. How many kilograms should a child weigh by age? Teenagers are the norm for height and weight.

The children's height and weight chart gives a rough estimate of your baby's physical development. It indicates low, average (normal), high and very high indicators of the child’s weight and height.

Very low and very high scores indicate a deviation from the norm. Indicators in the range below and above average are considered standard.

Assessment of a child’s physical development

Child development is assessed according to four indicators:

  • Height;
  • Head circumference;
  • Chest circumference.

In this article we will talk about the first two parameters, given in accordance with the norm adopted by WHO.

The World Health Organization (WHO) conducted a series of studies between 1997 and 2003 on the development of healthy children from 0 to 24 months, and in a cross-sectional study from 18 to 71 months. Research includes parameters of the child’s height and weight, their relationship and the monthly norm of physical development.

Indicators of physical development of girls and boys under one year of age

The height and weight of a child up to one year are the most important parameters for determining the normal development of the child. The nurse or doctor weighs the child monthly, measures his height, chest and head circumference, and records these figures in the medical record. What factors are taken into account?

  • Maternal nutrition after conception.
  • Gender of the child.
  • Weight and height of the child at birth.
  • Nutrition - height and weight directly depend on the daily intake of protein, carbohydrates, fats and calcium, vitamins and other microelements.
  • Previous illnesses: ARVI, intestinal infections, severe dehydration, teeth thinning and loss of appetite.
  • Genetics - the presence of disorders, congenital pathologies, chromosomal diseases.
  • Social conditions in which the child is raised. Problems in the family environment directly affect the growth and development of the child. They lead to a delay or even arrest of development, and the genetic material that was passed on from parents to child does not reach its full potential. Children who develop in an environment filled with love, joy, peace and trust develop more harmonious and healthy bodies;
  • Sleep - a child grows most rapidly during sleep. Systemic lack of sleep actually affects the development of the baby.

If a child is born prematurely or underweight, the weight and height of such a baby will differ from those of children born from 38 to 42 weeks of pregnancy and normal weight.

Weight and height chart for girls under one year old

Weight and height table for a boy under one year old

Characteristics of the first year of life

  • The average (normal) birth weight of a baby is between 3.2 kg and 3.7 kg.
  • The baby may have a normal birth weight, but the baby may even lose some weight in the first week of life.
  • The weight of newborns is added monthly at the following average rate: from 1 to 3 months - 750 g, from 4 to 6 - 700 g, from 7 to 9 - 550 g, from 10 to 12 - 350 g
  • When bottle-fed, babies gain weight quickly.
  • The height range of a child may vary depending on the weight, gender, and overall development of the baby.
  • The growth of a newborn increases monthly according to the following average pattern: from 1 to 3 months - 3.5 cm, from 3 to 6 - 2.5 cm, from 6 to 9 - 1.5-2 cm, 9-12 - 1 cm per month .
  • The most intensive growth is observed in the first months of life, then it slows down slightly, and at the end of the first year of life the child grows even more slowly.
  • The normal weight of a child for one year ranges from 8.9 kg to 9.6 kg.
  • The average height of a 1 year old child is from 74 to 76 cm.
  • In the first year of life, a child can grow by 20-25 cm.

Infants under one year of age are especially sensitive to underweight. Slow weight gain may indicate anemia, malnutrition, rickets, immune deficiency, endocrine disorders, and central nervous system disorders. With stable weight loss, delays can begin not only in physical, but also in mental development. It is important to ensure that the breastfed baby has enough breast milk. You can also add formula during breastfeeding.

Height to weight ratio in children

As we have already indicated, height and weight, considered separately, are not informative enough to determine the normal development of a child. Pediatricians are interested in their ratio - the correspondence of a certain height to a certain weight. If they are within normal limits, it means that the child is developing harmoniously; deviations from the norm indicate disorders that may be pathological.

Body mass index for children Quetelet

This is the formula for calculating your height/weight ratio. It doesn't take age into account. This is just the weight in grams divided by the height in centimeters. The Belgian statistician and mathematician Adolphe Quetelet developed an index that indicates the harmonious development of newborns:

Birth weight: height at birth = 60 – 70
The number to the right of the equality shows the index. In the range from 60 to 70 it is harmonious and healthy, and anomalies are pathological.

Example : The baby was born with a weight of 3.350 kg and a height of 52 cm - this is normal. But with a height of 56 cm, its mass is too low.

3350 g: 52 cm = 64.4 - normal
3350 g: 56 cm = 59.8 - below normal, the child’s height is below normal
3350 g: 47 cm = 71.2 - above normal, child above normal

Using this formula, you can always calculate how your child is developing (within what limits). It works during the next months after birth, without taking into account age itself.

And for older children, a Quetelet index below 60 means underweight due to intrauterine malnutrition. For what reason - should be clarified.

The Quetelet index and calculation formula are valid only for children born during term birth . For premature infants, there are other indices and formulas.

Forecast indices

Other formulas allow you to predict the final growth of a child - they take into account the genetic basis:

Hawker's formula

Boy's height = (father's height + mother's height): 2 + 6.4 cm
Girl's height = (father's height + mother's height): 2 - 6.4 cm

Formula for Frame

Boy's height = (Father's height + Mother's height X 1.08): 2
Girl's height = (Father's height x 0.923 + Mother's height): 2

Smirnov/Gorbunov formula

Boy's height = (father's height + mother's height + 12.5): 2
Girl's height = (father's height + mother's height - 12.5): 2

With this formula, the resulting height changes by +/- 8 cm.

Checking the parameters using specific examples showed that the third formula is closest to reality.

The child’s height/weight is not normal: why, what to do

The real sign of a problem is not a specific indicator that does not match the table, but general deterioration of the child’s condition + weight problems. Weight loss in combination with any of the following is a worthy cause for concern:

  • The child suffers from severe dermatitis;
  • Its development is periodically disrupted - it becomes chaotic, stops;
  • The child periodically suffers from complications;
  • He gets excited easily or, on the contrary, is too calm.

In the above cases, being underweight is just one symptom of the problem.

When the baby is alert and healthy, deviations from 75% to 125% from the data in the table n are not a cause for concern. Variation comes from factors such as genes, food, lifestyle. To make sure your baby is developing properly, check the head circumference as well as the chest circumference. An alarming sign of going beyond the norm is when some indicator reaches an extreme - plus or minus.

Growth disorders in children - why?

Suspicion falls on hormones or pathologies of internal organs, if there are no adverse external effects - for example, injuries, if the child receives proper care and proper nutrition.

  • Problems may be associated with endocrine disorders.
  • Skeletal dysplasia and chromosomal diseases accompanied by short stature.
  • Pathologies of the kidneys, liver and gastrointestinal tract.
  • Indirectly - liver problems.
  • In addition, growth disorders in children include some hereditary forms of pathology, for example, familial short stature.

Overweight in a child under one year old: why, what to do

Problems usually arise with artificial nutrition. In most cases there are three reasons:

  1. Baby food is not properly selected, does not meet needs, or is not used correctly by parents. for example, the mother thinks that the diluted formula does not taste at all, and, to correct this, she adds more mixture than indicated. The child gets extra calories and gains weight with all the health consequences.
  2. Overfeeding - if you act on the principle “the child will not eat more than he needs” - then you are mistaken. In fact, the baby obeys his sucking reflex and absorbs extra calories.
  3. A genetically determined abnormality or nervous system control over the gastrointestinal tract is not developed for some reason.

The specific cause must be determined by a pediatrician.

You should also take into account the following nuances when feeding infants: if regular food does not cause a rash and changes in stool in the child, parents often prematurely begin to give him food from their table in addition to formula.

As a result, some 4-month-old babies are already eating half a banana, others are scratching their gums on a cookie, thereby taking in additional food several times a day. This can result in excess weight, and sometimes in underweight (if nutrition is insufficient).

The problem is not weight, but...

Most of the problems are related to overprotective parents and a number of psychological problems inherent in our culture.

Many grandmothers and mothers believe that a child should be well-fed. Fatness is an indicator of health. They do not take into account that physical indicators are individual, they still tend to compare their child with other children. In our culture, we respect physical strength and people in the body. It is believed that someone else’s child, who is a few grams fatter or a few centimeters taller, is more developed. The mother is probably on a diet, but she feeds the child excessively so that it is no worse than others. And grandmothers who suffered from hunger and poverty want to “provide” the future generation with red cheeks and plump legs.

Weight and height of girls and boys from one to ten years

What is the relationship between a child's weight and age during this period? As in early childhood, it is important to take into account genetic predisposition, previous diseases, and congenital pathologies. But no less important factors are diet, lifestyle, and individual metabolic characteristics. It is also necessary to take into account the correspondence between the height and weight of the child.

Teen Height and Weight Chart

The weight and height of children in this age range are characterized by a wide range of norms. With slow development in a boy and much faster development in a girl, complexes can form. It is important for a teenager to psychologically adapt to the changes that occur in his/her body in order to explain the reason for these changes. Teenage girls are strictly prohibited from dieting and adjusting themselves to the “beauty standards” established in society.

Characteristics of physical development during puberty

  • As a rule, girls develop physically until they are 17-19 years old.
  • Boys grow up to 19-22 years old.
  • Intensive growth in girls was observed at the age of 10-12 years.
  • A boy's intensive growth usually begins later - from 13 to 16 years.
  • The growth spurt is explained by the hormonal surge during puberty.
  • The table shows the average indicators of the norm and deviations from it in terms of height and weight of children. It is always necessary to take into account the individual characteristics of the body and genetic predisposition.

The height and weight of the child by month and year are reflected in the standards proposed by WHO. It is important to consider a number of individual factors that influence the physical development of girls and boys. If there is too intense or, conversely, a slow increase in height and weight in children of any age, consult a neurologist, gastroenterologist, or endocrinologist.

What are the growth standards for teenage girls and boys? Reasons for height not meeting age standards.

To understand whether the child is developing normally, parents refer to the established parameters of the age norm. Do growth rates always fit within these parameters? And what to do if the child’s growth deviates significantly from the norm?

Teenage growth chart: height norms for girls and boys

Individual variants of development rates have a wide range associated with body features fixed genetically.
When assessing the level of physical development, it is necessary to take into account the physical development of his parents. The formula for calculating the expected final height of a child depending on the height of the parents is presented below. Please note that the result error is +/- 6 centimeters.

As a result of anthropometric examinations of large groups of adolescents, standards and norms of physical development were determined. In the proposed tables, growth indicators are divided into levels, so-called “centiles”.





If your child's growth rate is within the green or blue zone - his height corresponds to the average height, the yellow zone indicates that growth is normal, but there is a tendency to lag or advance, this can be discussed at an appointment with the pediatrician. If the growth rate is in the red zone, this may be a sign of a disease, do not delay consulting an endocrinologist.

Physical development and physique are 70% determined by heredity, and 30% by environmental factors.

Height to weight ratio in teenagers: height and weight table



To assess physical development indicators, it is important to evaluate not only height separately from other indicators, but also its relationship with weight.

The optimal ratio of height and weight in children and adolescents is presented by the following centile graphs. The method for assessing indicators is similar to the method for assessing centile tables described above: in the range from 3 to 97 centiles we can talk about the norm, everything above or below these values ​​requires the attention of parents and doctors.

Periods of accelerated, intensive growth of a teenager



With the onset of puberty, there is a significant increase in the linear size of the body and its weight - the so-called pubertal growth spurt occurs.
For girls The growth spurt begins on average at 10.5 years, growth increases most significantly between 11 and 12 years - the increase in body length can reach 8-10 cm per year. By the age of 13-13.5 years, the rate of increase in height decreases, changes in the ratio of body parts continue.
In boys the period of accelerated growth begins 1-2 years later, at 115-16 years the growth rate reaches a maximum (the increase in height can reach up to 8-9 cm per year), and slows down by 18-19.

Thus, girls “stretch out” earlier and at the age of 11-14 are superior to boys, both in height and in body weight.

The intensity of growth during puberty can be either uniform or spasmodic. In the latter case, the entire annual increase can occur in a few months - more often in the summer-autumn period.

During accelerated growth, there is a significant change in the proportions of a teenager’s body - awkwardness of figure, lankyness, long and thin limbs. This can lead to temporary incoordination of movements. The teenager himself may negatively evaluate such body features, which in turn becomes the cause of negative feelings about his appearance and self-doubt.

Without exception, all physiological functions of an adolescent undergo significant changes during the period of active growth. This can lead to imbalances in individual body systems. In most adolescents, muscle tissue does not keep pace with the growth of the skeleton, and so-called “growing pains” appear. The cardiovascular system also undergoes profound physiological changes, which causes sudden surges in pressure.

Small height of a teenager: how to increase?



Short stature in a teenager can be genetically determined, that is, it can be a variant of the norm.

To distinguish genetic short stature from short stature caused by other causes, it is necessary to take into account the height of the adolescent's parents, analyze the growth curve and determine bone age.

  1. Plotting a growth curve provides a more complete picture than comparing single measurements to average growth rates. If the child’s growth curve in all age periods is located below the optimal curve, and at the same time parallel to the lower limit of the normal curve, then most likely we are talking about genetic short stature
  2. Information about bone maturation is provided by x-rays of growth plates. For this purpose, in children over 2 years of age, an x-ray of the left hand and wrist is taken, from which the doctor can determine bone age. Normally, the condition of the bones should correspond to the age of the child

Short stature, not associated with genetic predisposition, can be caused by the following reasons:
insufficient nutrition in general or deficiency of some of its components (vitamins, microelements), impaired digestion and absorption in the intestines
excessive physical activity
various chronic diseases
chromosomal abnormalities
hormonal disorders

A detailed medical examination will help determine the cause of a teenager’s short stature; first of all, attention is paid to the state of the endocrine, cardiovascular systems, kidneys and liver. Treatment for short stature is determined by the doctor and depends on the identified cause of the disease.

Tall teenagers



Tallness is considered less of a problem for a teenager than short stature, and is sometimes seen as an advantage.

Constitutional-hereditary, or genetic tall stature is caused by the high growth of parents or immediate relatives, is considered the norm and does not require any treatment. In this case, the teenager:

  • growth rates correspond to normal rates in all age periods (this can be seen when plotting a growth curve)
  • bone age corresponds to chronological
  • there are no pathological symptoms of the central nervous system or endocrine glands

If a teenager’s high stature is not associated with heredity, it is necessary to pay attention to his health, first of all, to the condition of the endocrine organs. Another reason for the high growth of a teenager is chromosomal genetic abnormalities. In such cases, it is necessary to seek medical help for diagnosis and necessary treatment.



As we noted above, during a period of active growth, the importance of good nutrition is very high. Vitamins are necessary for the functioning of enzymes that regulate biochemical processes in the body. Each of the vitamins is “responsible” for its own “section” of metabolic processes, which is why there are several dozen diseases caused by vitamin deficiencies.



Exercises for growing a teenager's body

Many teenagers and their parents are very worried about short stature and are ready to do anything to “grow up,” including such radical measures as taking hormonal medications or surgery.
There is a way to speed up the growth of a teenager’s body without the risk of complications or side effects from taking various drugs - this is physical training.
