Child's body weight by month. Standards for height and weight of children - when should parents have no reason to worry? Anthropometric parameters at birth - what is the norm for newborns

Height and weight are measured in a child almost immediately after birth, in the fifth minute from the moment of birth. These indicators are of primary importance for assessing the baby’s condition throughout the first year of life. Using the treasured numbers, doctors judge whether the baby is healthy and whether he is developing normally.

Average weights for children from 0 to 12 months

Normal weight indicators in infants under one year of age have a significant relationship with many factors. For example, this is the chosen method of feeding and further feeding the baby, the lifestyle of the parents, and even the geographical place of residence of the mother and baby. But despite all of the above, the medical community has developed a table with parameters as an example of the norm for most children under 12 months.

The growth of a baby under one year of age increases dynamically, taking into account the constitutional characteristics, genetics, nutrition and general health of the baby. A slight deviation from the average parameters is not a cause for concern. If growth rates are far outside the acceptable range, this is an alarming sign that requires consultation with a doctor.

On a note! The data given in the table are considered standard when assessing the physical development of infants. However, it is worth remembering that babies are born with different weight categories and continue to gain body weight unevenly. So, one baby can “get heavier” by 0.5 kg in a month, and another by a whole kilogram; but as a result, the increase in both children can be considered the norm, taking into account their individual development.

How are child height and weight standards calculated?

The calculation formula is used if parents need to track changes in the baby’s body weight, comparing each result with growing monthly norms. One of the approximate weight calculations used by pediatricians from the moment of birth until the first birthday is presented in a simple formula - M (kg) = m + 800n, where M is the baby’s body weight, m ​​is the body weight at the time of birth and n is the current baby's age in months.

The rate of weight gain up to a year is usually recorded in the clinic by entries in the medical record, but they can also be monitored at home using special scales. If in short periods the scales show slightly less or more data in the table (with a difference of up to 150 g), then there is no need to worry, this is within normal limits.

Important!Sometimes a child’s weight gain differs significantly from the data given in the table. Large fluctuations in both directions should alert parents. If the lag is more than 350 g or more, something is wrong. Low body weight can seriously affect the development of an infant. If they come along with numerous complaints and disorders in the baby’s health, then the child must be examined by a pediatrician and neurologist.

Table of height gain for infants from 1 month to one year

The growth of a child from birth can be influenced by hereditary factors and, to a greater extent, by the constitutional characteristics of the little person’s body. Growth spurts can be especially noticeable between 3 and 4 months, and also between 6 and 8 months. At this time, in just one night the baby can gain a whole centimeter in length.

Calculation of the baby’s body length can be done using the approximate formula used by pediatricians: L (cm) = 100 – 8(4 – n), where L is the normal body length, n is the baby’s current age.

Anthropometric parameters at birth - what is the norm for newborns?

According to the World Health Organization, the body weight of a full-term baby is considered normal if it is between 2.5 and 4.5 kg. Moms and dads should know that WHO weight indicators are generally indicative.

If the expectant mother has gone through 9 months of pregnancy without serious complications, the baby’s weight will most likely be 3 – 3.6 kg. If the baby was born earlier than expected (before the 37th week), then its weight will be on average 2.5 kg. But there is no need to worry - after a while, a tiny newborn will definitely catch up with his peers. This is facilitated by maintaining a sleep and rest schedule, nutritious nutrition and finding the little person in a favorable living environment.

The table below shows the height and weight of boys, as well as the height and weight of girls in the form of average parameters, indicating the order of maternal birth.

Immediately after birth, most infants lose up to 10% of their initial body weight, so nature intends to rid the baby of excess fluid and accumulated meconium (feces). But after 7-12 days, the weight loss is replenished:

• in the first weeks of life, the baby gains at least 125 g per week;
• from the second month of life, the set is 600-800 g per 30 days.

Having noticed that the baby’s weight is noticeably lower than the prescribed norms, parents should figure out whether there is a reason for concern? Each baby develops at its own pace, so slight variations in height and weight are quite acceptable. If up to the age of three months the toddler gains at least 0.5 kg per month, and from the third to six months, 0.3 kg, and there are no complaints, then there is no reason to worry.

Important! Normally, during the first year of life, babies triple their initial weight (for example, from 3 kg to 10 kg). Girls often gain weight at a lesser rate than boys before 12 months. The acceptable difference in children of the same age can be up to 600-800 g.

How does a newborn gain weight (by week)

Active weight gain in infants occurs in the first eight weeks of life. This is a normal reaction of a child’s body to a change in living conditions, and adaptation to a new diet and regimen.

The digital value of height and body weight indicators in infants is very arbitrary and depends on many factors:

• choice of feeding the baby (mother's milk or adapted formula);
• the amount of food the child eats per day;
• the presence of diseases that prevent the proper absorption of food;
• activity and the amount of time the child spends sleeping and awake;
• often - gender (girls often gain weight more slowly than boys).

Important! Pediatricians calculate height and weight standards for infants in conjunction with tables of the average statistical norm, but in some cases they use experimental calculations. Often, insignificant deviations of indicators from WHO tables are considered acceptable. We also must not forget about genetic heredity - if below average height prevails in a family, you should not expect that the heir will gain 5 cm per month.

Weight and height of the baby after birth - what to pay attention to

In the maternity hospital, doctors record the weight and body length of a newborn baby and carefully monitor changes, especially in low birth weight and premature babies. They are weighed once a day at the same time, mainly in the morning.

• Daily weight gain is considered normal at the rate of 15 g per 1 kg of body weight. Growth is measured only once a week, and its increase will be assessed after 3-4 weeks. By this time it should be at least 2.5-3 cm.
• Most infants, after gaining initial weight, subsequently gain weight quickly, especially during periods of growth spurts. They occur approximately in the middle of the second week of life, and then between 3 and 6 weeks.
• The average child gains an average of 20 grams per day. By the end of the first month of life, the scales at the clinic will show approximately 3.8-4 kg. The height and weight of boys is usually slightly higher than that of girls - the difference in weight can reach 0.4 kg and 1-1.5 cm.

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

If an infant was born prematurely or weighed very little at birth, then the norms for growth and weight gain for him will differ significantly from the norms for babies born on time.

Degrees of prematurity of the baby (WHO information):

Birth weight largely determines a child's ability to adapt to life outside the womb. If the baby was born 2.5 kg, this process will take place without deviations from the desired course. If the baby “did not reach” this figure, then adaptation can be much more difficult. What to do?

First, keep warm

In children with low body weight, the layer of subcutaneous fat is very thin, almost absent. In this case, it is difficult for kids to keep warm and the danger of hypothermia is quite real. The temperature of a small baby should be measured at least once every 5-6 hours. If it is below 36.5°C, the baby must be warmed. The best way is skin-to-skin contact between mother and baby. Mom puts on an unbuttoned shirt, and the baby is placed on her chest. This way, the child’s temperature and pulse normalize, and the mother’s emotional state improves.

Second, we feed the baby by the hour.

This is a necessary condition, because in underweight children, the level of glucose in the blood often falls below the required level. This can cause sleep disturbances in the baby and a decrease in overall vitality. The best prevention of this condition is to frequently put the baby to the breast. In the first days, the child should drink about 60 ml of milk per day. Then the volume of liquid drunk per day should increase daily by 20 ml per 1 kg of body weight until it reaches 200 ml per 1 kg of body weight. Those. with a weight of 2 kg, the child will need to be given at least 400 ml of milk per day (of course, the amount is divided into 8-10 doses).

Third – massage for appetite and general development

If the child has gained the coveted 2500 g, and the doctors (pediatrician, neurologist) give the go-ahead for massage therapy, it’s time to undergo several strengthening procedures. Massage promotes weight gain, as it whets the appetite even in such babies. It is carried out an hour and a half after eating. It is better for a professional children's massage therapist to massage the baby, or the mother can master it on her own. After lubricating your hands with cream, you need to carefully knead the baby’s muscles according to the pattern from top to bottom - starting with the neck, then the back, buttocks, legs. At the end of the procedure, massage the arms and chest.

Weight and height gain by month: a quick overview of up to a year

Criteria for proper baby development can be confusing for new parents. If it’s difficult to figure it out, you can always ask your local pediatrician for advice. The main thing to remember is that when calculating measurements, you should focus on the initial data at the birth of the baby and only then calculate the individual monthly amount of weight gain and body length.

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.

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:

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:

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:

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:

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:

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

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:

Table of growth indicators for adolescent girls:

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 boys have not yet begun to undergo hormonal changes in their bodies. 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:

Height chart for boys under 17 years old:

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 once 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 a meal - 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.

Weight and height tables and graphs are based on data from the World Health Organization (WHO).

Many factors and characteristics will influence a child’s height and weight. Every child develops differently. However, it is important to monitor and prevent developmental deviations in time. The tables and graphs provided on our website will help you determine whether the child’s height and weight are within normal limits. Under no circumstances should you panic or worry ahead of time. Perhaps deviations from the average values ​​are simply a feature of development or, for example, heredity. But one way or another, if you do not see positive dynamics, you should definitely consult with an experienced doctor!

Height and weight tables allow you to determine whether a child has deviations from the average values. The graphs on our website allow you to visualize the child’s physical development relative to the norm.

Historical background (WHO tables and graphs)

Since the late 1970s, reference development indicators adopted by the National Center for Health Statistics/World Health Organization (NCHS/WHO) have been used.

In 1993-1994, WHO concluded that the reference indicators used do not adequately reflect early child development and have many shortcomings. The shortcomings were very serious and this interfered with the optimal management of feeding of young children. New norms of development needed to be explored.

From 1997 to 2003, WHO conducted large developmental studies to create new curves for assessing infant and young child development. The study was called the Multicenter Growth Reference Study (MGRS). The total number of children studied was 8440. Some of them were excluded from the study due to illness or other complications. Studies were conducted on children in Brazil, Ghana, India, Norway, Oman, and the USA. In this way, it was possible to collect statistical data from countries with different climates, cultures and other characteristics.

During the study, the Standard Child Development Indicators were adopted:

• body length (height) - age
• body mass (weight) - age
• body weight - body length
• body weight - height
• body mass index (BMI) - age

Here it is worth paying attention to the differences in the concepts of body length and height. Body length was measured in children aged from birth to 2 years in the supine position. Height was measured in children aged 2 to 5 years in a standing position. The final statistics for children aged 18 to 30 months take both values ​​into account. In our tables and graphs, we use the word “growth” for simplicity.

Content

The birth of a child is a major event for parents. To assess and monitor his physical development, special age tables of height and weight for children have been developed. Figures are given that indicate standards corresponding to a certain age of the baby. Very large or low values ​​indicate standard deviations; values ​​that deviate slightly from the average indicate compliance with standards.

Standards for height and weight of children

The World Health Organization conducted a Multicenter Study of Developmental Indicators aimed at determining the physical development of children, which included the height and weight of the child by year. The need to study the issue is dictated by changes in living conditions and climate, which affect the development of children. The weight and height indicators of children under 5 years of age depend not only on heredity, but also on the type of feeding for the first 24 months of life. Children fed formula gained 16-20% more weight than those growing up on breastfeeding.

WHO experts believe that inflated standards were obtained after recommendations from pediatricians on supplementary feeding of infants, which led to the transition to artificial feeding, overfeeding and obesity. Previous norms for assessing the physical indicators of children are not the absolute truth. By 2006, WHO made adjustments, determined new data, after which age tables of height and weight of children were compiled.

The anthropometric indicator of body size depends on the characteristics of each baby. The ratio of height and weight in children is determined by many factors: nutrition, sleep duration, physical activity, and genetics. The average height of a man is approximately 178 cm, a woman is 164 cm. Boys are formed by the age of 22, an intensive period of growth is observed at the age of 13-16 years, girls - up to 19, actively growing from 10 to 12 years. The teenage period is characterized by a sharp growth spurt, so the proportionality of the body is not always observed.

Height to weight ratio

Height is a global indicator that public health takes into account when assessing children's development. Commonly accepted estimates of this parameter:

1. Obviously undersized - severe retardation, possible presence of congenital pathologies and chromosomal diseases.
2. Short stature – large underweight, sometimes overweight.
3. Below average - the value is small, but corresponds to the norm.
4. Average (kind of standard).
5. Above average - growth is large, but meets the standard.
6. Tall is a hereditary predisposition.
7. Overestimated - there may be endocrine system disorders.

Both parents and doctors should pay attention to the baby’s growth indicators. Factors influencing tall stature and growth retardation:

1. Chromosomal genetic – manifested by disproportionate sizes of feet, hands, face, mental disorders, problems with sexual development.
2. Constitutional-hereditary - no developmental deviations.
3. Early sexual development (8-9 years). Children are taller than their peers, but as they grow up, they remain short due to early closure of growth plates.
4. Endocrine-increased levels lead to gigantism or acromegaly.

Endocrine control of children's physical indicators is important for the optimal balance of these indicators. A young child, boy, girl over 15 years of age may have the following weight estimates:

1. Significant underweight means serious depletion of the body.
2. Low weight.
3. Less than average is the norm, but the indicators are at the lower limits.
4. Average – body mass index (BMI) within normal limits.
5. Above average – slight excess weight.
6. Overestimated – overweight, obesity.

Table for children under one year old

When measuring the size of a child, you need to understand that up to two years we are talking about the baby’s length - because he cannot walk or stand, after 3-4 years - about height. Attention is drawn to many factors. Children's parameters by month are studied by a health worker during the first 12 months of life. It takes into account:

• baby's gender;
• physical characteristics at birth;
• heredity;
• past illness (if any);
• presence of pathologies;
• social conditions;
• feeding (artificial or breastfeeding).

If prematurity or low birth weight occurs, the baby's height and weight chart will differ from normal children. A one-year-old baby gains a certain body weight in 12 months. The average weight indicator is 6-7 kilograms. The main increase occurs in the first 6 months of the baby’s life. The baby has a monthly gain of about 1 kg. With proper feeding, a low-weight newborn is able to “catch up” with children with normal body weight in 6 months. By the end of the 12th month, the baby weighs from 8 to 12 kg, height – 75-80 cm.

Parents should understand that the data given in the tables may differ by approximately 2-3 kilograms, a couple of centimeters in different directions. This will not be considered a violation of the norm. However, if there is improper nutrition, overfeeding, hormonal imbalance, or a change in daily routine, then the deviations will be significant. This is a serious reason to consult a pediatrician and undergo an examination to diagnose the correct disease.

Growth by month

The height and weight standards for children under one year of age are shown in the table (girls). The scale is indicated in centimeters (see table):

The physical characteristics of boys are higher than those of girls. Body length by month (in centimeters):

Weight by month

The normal body weight of a girl at 12 months of age varies between 8-10 kg. The standards are as follows (in kilograms):

Boys' body weight is greater than that of girls. Weight table by month (in kilograms):

Child's height and weight by age

From birth to ten years of age, children experience a rapid increase in height. However, if up to 12 months the changes were clearly visible, then the baby grows a little more slowly. This is explained by the fact that metabolism changes; a child’s growing body spends more energy than that of an infant. The baby's diet is higher in calories, but the energy received is quickly consumed. Below, the table of children’s growth by age gives an idea of ​​the norms of physical indicators for children under 10 years of age.

Age tables show that in the period from two to three years the baby continues to grow, but not so quickly. Weight range: 12-14 kg. This is explained by the baby’s great activity and mobility. The change in height is insignificant: it increases by about ten centimeters. Further:

• The age of 4-5 years is characterized by an increase in body weight by a couple of kilograms, deviations from the norm by 2-3 kg are possible.
• At 5 - weight reaches approximately 18 kg, height approximately 109 cm.
• At 6, the weight norm is 18-23.5 kg, height – 112 cm.
• By 7 – the weight will increase by 2-3 kilograms, the height will be approximately 115 cm.

						From 11 to 18 years old At 11-18 years of age, the intensity of the set of physical indicators changes. Parents need to understand why a teenager is extremely unstable emotionally. Physiological differences or sexual dimorphism are manifested by external signs, structural features of the body, and the functional capabilities of individual body systems. All these changes have an impact on the minor. Girls begin to develop earlier; at the age of 12-14 years, their indicators are higher than those of boys. However, by the age of 15-16, boys surpass girls in physical development. Adolescence for boys is characterized by active growth of the tubular bones of the skeleton. This manifests itself in the extension of the limbs, although the torso lags a little behind in this race. Because of this, one often gets the impression that the teenager is awkward and disproportionate. The chest remains narrow, the muscles are weak for such a size, which leads to stooping and the inability to hold the back straight for a long time. Muscle mass increases more slowly than bone mass. It is thoroughly established at the age of majority. The weight increases slowly, but unevenly: the norm for boys ranges from 2.4 to 5.3 kg over 12 months, for girls - from 2 to 5 kilograms. After the age of 15, girls' body weight increases more than their height. This process is associated with an increase in muscles, subcutaneous fat, and the development of skeletal bones. This is the period when motor reactions and coordination of movements become more accurate, spatial and muscle sensations develop. Features of puberty The sharp jump in physical indicators is explained by hormonal activity. Puberty differs between girls and boys. At this time, it is important to control the body weight of a teenager - prevention will protect not only from many serious diseases, but also emotional outbursts that manifest themselves during puberty in minors. However, dieting is prohibited. Proper nutrition skills need to be instilled from birth. To normalize height, it is necessary to take vitamins. Puberty in boys goes through several stages and lasts several years. It is characterized by the onset of hormonal maturation of the gonads and reaches its peak in adolescence (13-18 years). At the age of 18-19 the time of puberty begins. In parallel with these changes, muscle mass increases and the whole body grows. The figure becomes masculine: the shoulders expand in comparison with the pelvic bones. Puberty in a girl is manifested by the active “play” of hormones called estrogens. They force the body to grow quickly: hair appears in the groin, armpits, and breasts enlarge. Girls who mature too early should be under special adult supervision. Puberty in girls lasts approximately 7-8 years. Physiological features characteristic of a teenager during puberty: the contour and proportions of the head change; the skeleton is finally formed; boys have hyperplasia of the muscles and shoulder girdle; in girls there is hyperplasia of adipose tissue and the ilium; boys experience dizziness and fainting; girls become capricious, touchy, and hot-tempered.

This calculator estimates the weight and height of a child according to his age, accurate to the day. Unlike, this calculator gives a comprehensive assessment of weight in strict accordance with the height and age of the child.

The ranges of values, methods and recommendations are based on methodological materials developed by the World Health Organization (WHO), which has conducted extensive research on the development of healthy children of different nationalities and geographical areas.

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

If our calculator shows you that there is a problem, then do not rush to panic: measure your height again, and have two different people take the measurements in turn and independently of each other.

Height or body length

In children under two years of age, it is customary to measure body length in a lying position, and from two years of age, height is measured, respectively, in a standing position. The difference between height and body length can be up to 1 cm, which may 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 will automatically be converted to that required for correct calculation.

What is the height (body length)

Growth is the most important indicator that should be monitored monthly (see). Receiving ratings of “short” and “very short” may be a consequence of prematurity, illness, or developmental delay.

Tall height is rarely a problem, but a rating of "extremely tall" 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 necessary to identify and eliminate the cause of the lag. short Growth retardation. It can also lead to excess weight. Specialist consultation is required. Below the average A short child, height within normal limits. Average This is the height of most healthy children. Above average Tall child, height within normal limits. High Such large growth is not common, but it does not indicate the presence of any problems, so it is considered normal. Usually this growth is hereditary. Very tall Excessive height in a child is usually hereditary and is not a problem in itself. However, in some cases, such growth may be a sign of an endocrine disease. Therefore, rule out the possibility of an endocrine disorder by consulting a specialist. Height does not correspond to age You probably made a mistake when indicating the child's height or age.
If the baby’s growth is really the same as you indicated, then there is a significant deviation from the norm, which deserves special attention from an experienced specialist.

How does weight correspond to height?

The ratio of height and weight gives the most meaningful idea of ​​the harmonious development of a child; it is expressed as a number and is called the Body Mass Index, or BMI for short. This value is used to objectively determine weight-related problems, if any. And if there are none, then they make sure that the BMI is normal.

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

Severe underweight (severe wasting) Severe body weight deficiency. Severe exhaustion. Nutritional correction and treatment as prescribed by a doctor are necessary. Body mass deficiency (underweight) Body weight deficiency. Insufficient weight for specified height. It is recommended to adjust your diet as prescribed by your doctor. Reduced weight Weight is within normal limits. The child is less well-fed than most of his peers. Norm Ideal weight to height ratio. Increased weight (risk of being overweight) The child's weight is normal, but there is a risk of gaining excess weight.
In this case, it is recommended to pay attention to the weight of the child’s parents, because Having obese parents significantly increases the risk of a child gaining excess weight.
In particular, if one of the parents is obese, then with a 40% chance the child will gain excess weight. If both parents are obese, the likelihood of the child becoming overweight increases to 70%. Overweight It is recommended to adjust your diet as prescribed by your doctor. Obesity Nutritional correction and treatment as prescribed by a doctor are necessary. Obesity: Nutritional correction is necessary as prescribed by a doctor. Not assessable You may have made a mistake when specifying the child's height, weight or age.
If all the data is correct, then there is a significant deviation from the norm, which requires special attention from an experienced doctor.

What is the weight

A simple weight estimate (based on age) usually gives only a superficial idea of ​​a child's developmental pattern. However, receiving ratings of “Low weight” or “Extremely low weight” is a good reason to consult a specialist (see). The full list of possible weight ratings is below:

Severely underweight, extremely low weight The child is probably exhausted. It is necessary to consult a specialist. Underweight, low weight The child is probably exhausted. It is necessary to consult a specialist. Less than average Weight is below average, but within the normal range for the specified age. Average Most healthy children have this weight. Above average In this case, compliance with the norm should be assessed by body mass index (BMI). Very big In this case, weight is assessed using body mass index (BMI). Weight is not appropriate for age You probably made a mistake when indicating the child's weight or age.
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.
