What are the normal height and weight standards? Do you know what a child’s height and weight should be by month? What determines the rate of weight gain and growth?

Girls usually grow a little slower than their male counterparts, and this is normal.

A table of girls’ height and weight by year will help you determine for yourself whether a girl is physically developed correctly and whether her height and weight correspond to age standards.

How much do the girls weigh and how tall are they?

Intensive growth and weight gain in girls occurs in the first year of life. You can assess whether these indicators are within normal limits using a table up to a year by month. It is worth noting that Russian data and WHO data differ slightly.

Another noticeable jump in these indicators accompanies puberty. And here girls are already ahead of boys: on average, a growth spurt in girls is observed at 10-11 years old, while boys lag behind by about 2 years. During puberty, the increase in height and weight of girls averages 25 cm and 25 kg, respectively. Girls grow on average until they are 18 years old. The average height of a Russian woman is 165 cm.

Centile tables for determining height and weight standards

You can evaluate how harmoniously developed a girl is using a centile table. The columns of the table indicate the quantitative limits of height and weight for a certain percentage of girls; The interval 25%-75% is taken as average indicators. In the case when a girl’s indicators fall into these corridors, then this is the norm. The columns before and after these intervals are indicators below (10%-25%) and above (75%-90%) the norm.
If the girl’s indicators fall into the extreme corridors, this is a reason to consult a doctor. It is very important that both the height and weight of the girl are in the same corridor (+/- one column). Otherwise, physiological development cannot be considered harmonious: dystrophy or obesity, lack or excess growth - one of these problems may affect a girl.

The correct ratio of height, weight and age can be assessed using these tables:

Girl's weight, kg

Conclusion

The height and weight of girls under 18 are indicators that often increase disproportionately. A girl can be plump with a short stature, and then suddenly she will suddenly stretch out and become slender. Or, on the contrary, from a skinny person to a plump one.
In order for weight and height to have an optimal ratio, it is important to eat a healthy and balanced diet, get enough time for sleep at night, as well as lead a moderately active lifestyle and expose the body to feasible and regular physical activity. It is not necessary to go to big sports; physical education at school, visiting the pool or sports section and walking are enough.

One of the first things you hear after your baby is born is his height and weight. This information is first entered into the child’s medical record, and it is also communicated to friends and relatives. I propose to figure out why exactly these indicators are so important.

Firstly, the height and weight of the child, as well as the circumference of the head and chest, help doctors correctly determine the condition of the newborn, suggest or exclude a number of diseases and pathologies. In the future, as the baby grows, these indicators serve as an indicator of the child’s physical development.

It is by the ratio of height and weight, as well as by the speed of development, that experts determine whether the sleep and rest schedule is correct, how to adjust the diet, and what physical activity will have a beneficial effect on the child’s body.

Baby's height at birth

The growth of a newborn at a gestational age of 38-40 weeks, as an important anthropometric indicator, can range from 46 to 56 cm. It depends on the blood flow of the placenta, the nutrition of the expectant mother, heredity, as well as the sex of the child
When assessing the condition of a newborn, short stature is not always a sign of poor development or prematurity of the fetus. For example, if the child’s parents are short, then the newborn may also be small
In addition, normal indicators fluctuate for multiple pregnancy, in which children are born shorter and weigh less. However, each case is assessed individually by pediatricians based on general anthropometric indications and the physical condition of the newborn.
The ratio calculated using the weight/height formula (Quetelet index) is important. For full-term babies, the normal value is 60-70

In the first year of life, given the active development of the baby, height is extremely important for assessing health and nutritional balance. It is believed that the norm is an increase in height of about 25 cm per year. Here is an approximate table of height growth in the first year of a child’s life:

In the first six months of a baby’s life, its weight is calculated using the formula: weight of the newborn + 800 * number of months. So, if at birth the child’s weight was 3200 g, then at 4 months the weight should be no less than 3200 + 800 * 4 = 6400 g.

After 6 months the formula becomes more complicated. Now we add 400g for each month from 6 to 12 months. So, take the same data for an 8 month old child: 3200+800*6+400*2 = 8800 - the average weight of the child.

Important: Height and weight are important indicators of a child’s development, and if you have any doubts about your baby’s growth, share them with your pediatrician.

A baby is considered premature before 38 weeks. Naturally, the height and weight standards for such children are different, and further development also occurs along a different path. For example, the normal growth rate for a premature baby at birth is 35-45 cm.

Premature babies develop differently. Parents in such a situation should calm down and not rush events.
If babies with normal weight gain their bulk and height in the first months of life, then a premature baby begins to actively grow, catching up with peers, only after 3 months
This is due to the fact that the baby needs to gain the weight lost at birth (and it makes up up to 15% of the total weight) and gain weight to normal

The increase in height during the first year of life is about 26-36 cm, in the first six months the increase is 2-5 cm per month Premature babies not only differ in size, they have different physical and mental development, which frightens many parents, because the child begins to hold his head up later, later walk, etc.

Important: Remember, the baby will not lag behind, he will definitely catch up with his peers. Sometimes strengthening massage courses can help him develop.

Child growth chart: growth standards for boys and girls from birth to 18 years

Growth is influenced by many factors - physical development, nutrition, and a properly adjusted sleep and rest schedule is also important. In addition, we should not forget about heredity and the fact that each child develops differently.

Anthropometric centile tables will help determine the approximate growth rate for your child. They are compiled based on an analysis of the growth of several million children, as a result of which the average statistical indicator by age is derived.

It is worth noting that growth standards for boys and girls are different. Find the child's age and height in the table and see which column it is in.

Table of height and weight norms for girls

The norms include height, which is indicated in the columns highlighted in red. Everything that is indicated to the left: 10% is below the norm within acceptable limits, 3% is beyond acceptable limits. The situation is the same with the columns to the right, only in the direction of increase.

Important: If your child’s height and weight are in the extreme columns, consult with specialists: pediatrician, endocrinologist, therapist.

How to calculate a child's height based on the parents' height: formula

Naturally, it is impossible to determine exactly how tall the baby will be, but it is still possible to make an assumption based on the hereditary factor. I suggest you familiarize yourself with the most popular formulas for calculating the height of boys and girls.

Height and weight ratio in children, tables

Of no less importance is the ratio of height and weight in a child, which reflects his physical development. Monitoring indicators over time will help prevent the baby from falling behind or developing obesity.
Even if your child is a couple of centimeters taller or shorter than his peers, or his height or weight does not fit into the age norms, you should pay attention to their ratio

Based on the above tables, you can make an approximate conclusion about the anthropometric indicators of your child.

Please note that you can also use a calculator to quickly calculate the ratio of a child's weight and height. You just need to enter your age, height and weight to determine your body mass index and developmental level.

Periods of intense growth in children: growth spurts

In the first year of a newborn’s life, approximately 5 so-called growth spurts are observed:

1-3 weeks
6-8 weeks
3 months
6 months
9 months

During growth, your baby may become whiny and will likely have a significantly increased appetite and require more time and food to satisfy his desires. If you are breastfeeding your baby, you may feel like you are not getting enough milk. The main thing is not to worry and continue feeding. Your body will do everything for you.

It is worth noting that in infants growth spurts do not last long - on average 2-3 days. In addition to increased appetite, you may notice increased anxiety during these periods, the emergence of new skills
Sometimes a growth spurt may be indicated by sudden sleep disturbances - the child wakes up more often or does not sleep at all, or, on the contrary, may fall asleep unusually soundly and for a long time

After a year, the child gains weight and grows more steadily. The next noticeable growth spurt occurs at approximately 6-7 years.

You need to understand that at this age extremely important changes occur in the child’s body, among which the first place is the formation of the musculoskeletal system and strengthening of the skeleton
Pay attention to the child’s posture; this is the time when problems with the spine can develop. The average height increase is about 8-10cm per year

Important: During the period of 6-7 years, it is difficult for a child to maintain one position for a long time or to remain motionless.

The next major growth spurt occurs during adolescent puberty. In this case, it is impossible to guess at what age it will happen. In girls, puberty occurs at 10-12 years of age, but in boys it is usually 1-3 years later. Growth per year can reach 8-10cm, sometimes more.

A growth spurt is accompanied by hormonal changes in the child’s body, and secondary sexual characteristics appear
Moreover, the child’s body often negatively experiences rapid growth and weight gain.
A teenager may begin to experience seizures, headaches, and dental problems.
Hormonal changes affect the child’s behavior: he may become whiny or aggressive, get tired quickly

During this period, it is important for you to ensure that your child receives all the necessary substances and vitamins. Please note that during a growth spurt, fluid requirements may increase by up to 20-30%.

Problems of very tall height in children

You can read in detail about the reasons that influence a child’s growth, the factors leading to high growth, as well as recommendations for parents of a tall child

My child is short, what should I do?

If your child’s weight is much lower than normal, do not rush to draw conclusions, because it is possible to influence growth until the growth zones have closed.

Important: Before taking any steps on your own, consult your doctor - insufficient centimeters in some cases can be a symptom of glandular failure.

Factors that can affect a child's growth:

Nutritious food
Healthy sleep, properly regulated sleep and rest patterns
Sports loads
Favorable psycho-emotional environment

What height and weight can a child have, video

Important indicators of the physical condition and health of children are weight and height. It is generally accepted that they depend on human genetics. Every child is different, but being overweight or underweight can indicate poor nutrition or serious health problems. Very fast or slow growth can be a signal of improper functioning of body systems.

The height and weight of a child is primarily influenced by genetics, but there are many more factors on which these indicators depend

What factors influence height and weight indicators?

The following factors influence height and weight indicators:

genetic predisposition (heredity, ethnic origin);
growth hormones;
diseases suffered at an early age;
functioning of the endocrine system;
hormonal surge during puberty;
psychological situation in the family;
nutrition and sleep;
chronic pathologies;
physical exercise;
hemoglobin level;
body weight is directly proportional to length.

What height and weight should the baby be born with?

At birth, the weight of a full-term baby ranges from 2500 g to 4500 g. Boys, as a rule, weigh more than girls. The maximum weight for a baby usually does not exceed 4.5 kg. Average weight – 3.2–3.4 kg. The body length of newborns is 45-54 cm. Average height– 49-52 cm. Body length in girls is usually in the range of 49–51 cm.

As you can see, the range of physical indicators of a child at birth is quite wide. The baby’s data is influenced by various factors: hereditary predisposition, at what stage the baby was born (38-40 weeks), and features of the mother’s pregnancy. It should be said that the same parents can have children with different physiological characteristics.

Height and weight of premature babies

The weight of children depending on the degree of prematurity:

If a premature baby is healthy, he quickly gains height and weight

Body length in children born ahead of schedule, usually less than 45 cm. Their physique is disproportionate, the subcutaneous fat layer is not formed, the sutures of the skull are open, and the skin is overflowing with blood. Newborns who have rushed into the world are nursed in special conditions. At proper care By the first year of life, such children are no different from those born on time.

WHO Child Growth Charts

All children develop at their own pace. However, there are certain norms for weight gain and height that doctors rely on when determining the child’s physical condition. These data are compiled into tables developed by the World Health Organization (WHO). Let's look at WHO tables using the example of girls' development.

Normal indicators in girls under one year old

In the first year of life, children develop most actively. Immediately after birth, newborns can lose up to 300 g in weight. However, in the first three months of life, the baby is able to gain up to 750 g monthly, in the next three months - 700 g, from 7 to 9 months of life - 550 g, 9-12 months – 350 g. Children who are bottle-fed gain weight faster.

Babies grow no less intensively. The ideal increase in length for babies from 1 to 3 months is 3.5 cm, 4-6 months – 2.5 cm, 7-9 months – 1.5-2 cm (see also:). From 9 months to one year, children grow another 1 cm per month. The average weight of a child per year is in the range from 8900 to 9600 g. Body length is from 74 to 76 cm.

On average, children are born with a weight of 2.9-3.5 kg and a height of about 52 cm

Based on the data, a weight indicator for a one-year-old baby of 7.9-10.1 kg is considered ideal (we recommend reading:).

Weight one year old girls can vary greatly - there are “skinny ones” and there are “chubby ones”

Low and high weight is not critical; it can be caused by genetic predisposition or characteristics of pregnancy. If your baby's readings are beyond low or high, doctors will conduct additional tests to rule out health problems.

Children's age from one to 10 years

In the period from one to 10 years, a child’s musculoskeletal system is formed and strengthened, and the functioning of all internal organs is improved.

With insufficient nutrition and improper distribution of physical activity, children can develop various diseases. Therefore, it is just as necessary to monitor the norms at this age as in infancy.

Monitor girls' height and weight standards school age just as important as in infancy

Development of girls from 11 to 18 years old

Ages from 11 to 18 years are considered adolescence. At this time, intensive changes occur in the children's bodies. This is especially noticeable in appearance. A chubby baby can turn into an ideal girl, and a skinny girl can gain shape. Such changes are caused by hormonal changes in the body. It is necessary to understand when such changes are normal and when to sound the alarm.

Consider the weight table for teenage girls:

Age, years	Weight, kg
Age, years	short	lower limit of normal	norm	upper limit of normal	high
11	24,9-27,8	27,8-30,7	30,7-38,9	38,9-44,6	44,6-55,2

The height of high school girls can vary greatly: from 150 to 175 cm

Is it possible to calculate a child's height based on the parents' height?

There are several formulas for approximate calculation of a child’s height in relation to the height of his parents:

To calculate a girl's height (RD), you need to add the father's height (RO) with the mother's height (RM), multiply by 0.51 and subtract 7.5 cm. The author of this formula is unknown.
Another formula belongs to the Czechoslovakian V. Karkus. RD cm = (RO cm*0.923 + RM cm)/2.
Dr. J. Hawker suggested calculating height as follows: RD = (RO + RM)/2 – 6.4.
Formula of Smirnov and Gorbunov: RD = (RO + RM -12.5)/2 ± 8.
Another formula calculates height based on the data of a child per year (CA). RD = RG + 100 cm – 5 cm.

Periods of intensive growth in children: when do leaps occur?

Girls develop at the fastest rate from 10 to 13 years. This is explained by active puberty.

During this period, the teenager’s body receives a major hormonal shock. During puberty, the future girl can grow by 8 cm per year. Her figure will also change significantly - weight gain or loss is possible.

If the child is too tall

Child height is considered a hereditary factor. If the parents in the family are tall, then the baby will be tall from childhood. However, too much deviation from the child’s age norms can be a signal that there are significant problems in his body. In addition to early puberty, high height in children can be caused by:

high content of growth hormones;
obesity;
chromosome pathology;
pituitary tumor;
Marfan syndrome;
dysfunction of the pituitary gland.

What to do if the child is very small?

The short stature of a child, if it is not due to a genetic predisposition, should also cause concern among parents.

If parents notice that the baby is not growing well and is not gaining weight, they need to consult a specialist.

The doctor will study the history of his height gains, examine the child, and analyze the diseases he has suffered. If the parents' doubts turn out to be justified, a thyroid examination is prescribed. To exclude rickets, the child is prescribed an ultrasound. In parallel with these studies, the pediatrician should prescribe tests to check the blood for growth hormone and hemoglobin levels. Sometimes a child's bone age is examined using bone x-rays.

If during the examination the doctor rules out that the baby has problems caused by illness or hormonal disorders, the child will be prescribed vitamins and special protein foods. For proper development, children need to eat vegetable oils, dairy products, fish and meat, vegetables.

To activate growth hormones, you need to do daily exercises and sleep at least 8-9 hours a day. The child should fall asleep no later than 22 hours. There is a theory that babies need the love of their parents to develop. In families in which children are surrounded by care, children develop more actively and get sick less.

The development of a child largely depends on his parents (see also:). Family climate proper nutrition, timely contact with a specialist will help the little man grow up big and healthy. Growth charts for girls and boys should be treated as reference information. You should not try to put the baby into a framework, but use the information as a guide.

The most important parameters for understanding how your child is developing in the most important - the first year of his life - are the baby’s height and weight. Therefore, it is simply necessary to visit a pediatrician every month to understand how the child’s height and weight changes over the months.

What to consider when comparing with standards

In order to determine how a child is developing, the World Health Organization (WHO) recommends taking into account the following parameters:

Gender of the baby.
Height and weight at birth.
Genetic characteristics of the parents (large, tall, short).
Previous intrauterine infections (mother's illnesses during pregnancy).
Are there any infections, viral diseases, teething, or reactions to vaccinations in the child at the moment.
Absence or presence of congenital disorders, diseases.
Social and living conditions of the baby.
Nutritional features.

If your baby was born premature or weighed very little at birth, then the norms for weight gain and height for him will be different from the norms for children who were born on time.

It happens that a baby is born with normal height and weight, but other indicators indicate immaturity:

A faint cry.
Breathing is irregular and shallow.
Soft ears.
Decreased reflexes.
Incompletely formed genitals.
Dry and wrinkled skin.

Degree of prematurity

Degrees of prematurity of the baby (WHO information):

If your child was born prematurely, we recommend that you find out more information: about the characteristics of his development, care for premature babies, possible problems and their correction. A book by a famous pediatrician with 30 years of experience and 35 years of research experience in neonatology will help you with this - Ola Zaugstad "Premature baby. If the child was born earlier.”

Term indicators

Physical data indicating that the baby is full-term:

Often the characteristics of a baby’s weight and height depend not only on the parents’ genetics, but also on the mother’s diet. And an important factor is the indicators of placental-uterine blood flow. Also, the anatomy and physiology of the female breast, the technique of breastfeeding, common diseases of women and children, the compatibility of breastfeeding with various foods and medications, methods of organizing breastfeeding - all this can affect the baby’s gain in height and weight. It will help you understand these issues in detail. Dr. Carlos Gonzalez in his book “The Gift of a Lifetime. Breastfeeding Guide"

Don't forget that according to WHO, girls and boys gain weight and grow differently.

Standards for children of the first year

The average weight of a baby at birth according to WHO recommendations is from 3.2 kg to 3.7 kg.
Weight loss in the first week of a child’s life is considered normal.
The baby gains the most in the first five months of life, then the weight gain gradually slows down.
If a child eats formula, he gains weight faster.
The growth of a child by month is very dependent on weight gain. First, the body devotes all its strength to gaining weight, and only then the baby grows.
The period from the first to the sixth month is the most active for a child’s weight gain and growth.
A normal child at the age of one year weighs from 8.9 kg to 9.6 kg.
The average child at the age of 1 year grows to 74 - 76 cm.
It is in the first year of life that the most active growth. During this time, the baby grows by 20 - 30 cm.

Important to remember

According to WHO information, young children in the first year of their life are especially sensitive to deficiency (lack) of body weight.

A very small weight gain may indicate anemia, an eating disorder or rickets, the possible presence of endocrine diseases and immunodeficiency, and lack of weight may also characterize disorders in the central nervous system.
If a child is underweight, not only physical retardation begins, but also a serious slowdown in mental and mental development.

Against this background, parents can observe two main problems in their child, which arise precisely when raising a child with underweight.

Problems

Vomits and gags while eating. A baby, under the age of one year, does not yet know how to chew, so he may choke; if the child’s nervous system is overloaded, then this may manifest itself in food in the form of vomiting. At the same time, grinding or grinding even more does not help.
Solution to the problem: arouse the child’s interest in food, let him learn to eat on his own, and control the process himself. Give your baby a piece of bread in his hand, a peeled cucumber or a piece of apple.
Refuses to sit on the potty.
Solution to the problem: Check if it is comfortable. You shouldn’t insist too much, much less forcefully hold your baby on the potty. This will only intensify the protest. You should offer to go potty calmly, choosing the time carefully. It is best to do this after sleep, after a long break, or 20 minutes after eating - this is the best time for the baby to go to the potty and understand what you want from him.

This is why it is so important to control your baby’s weight. If there is a lack of milk or during milk crises, it is recommended to supplement with a specialized formula. For low birth weight and premature babies, dry and ready-made formulas in jars have been developed that are convenient to take with you. They are designed to feed a child from birth until the age of 18 months. or weight gain up to 9 kg.

Learn more about the indications for switching to artificial or mixed feeding, how to choose a formula for your baby, how and when to introduce complementary foods, and much more. others are well described in book “Artificial and mixed feeding” by Elena Khramtsova.

Remember that each child is individual and all standards, including those specified by WHO, are only a guideline, but in no case a mandatory comparison. It’s important how the baby feels, how harmonious he is - that’s the only thing that matters.

If he is larger or smaller than he should be and at the same time cheerful, cheerful and developing well, then this is the normal height and weight for your child.

Child's height and weight are the main indicators of his physical development. That is why, immediately after the birth of the baby, they must measure his body weight and body length and continue to weigh himself every day at the same time until discharge from the hospital.

There are many factors that influence a child's physical development, for example:

heredity (you shouldn’t expect short parents to have a son who is a basketball player)
nutrition (it’s no secret that a deficiency of nutrients, vitamins and minerals slows down the growth and development of a child)
physical activity (for example, playing tennis, volleyball, basketball helps increase height)
child health (children with chronic diseases often lag behind their peers in physical development)
psychological situation in the family, at school, lack of sleep, etc.

How to understand what is normal?

All-Russian Health Organization Special tables for the height and weight of children, or as they are called, centile tables, are recommended. At each examination, the pediatrician measures the child’s height and weight and compares the obtained values with standard values. Such tables make it possible to identify obvious pathologies; for a more accurate analysis, the doctor calculates additional indicators using special formulas.

Deviations of weight or height from table values

There is no need to panic if there is a minimal discrepancy with the indicated values in the table, and here’s why:

First of all, child height and weight charts contain benchmarks, then what should ideally be the weight and height of the child, without taking into account many other factors. Sometimes parents of premature babies mistakenly use a standard table for comparison, while there are special tables for assessing the development of children born prematurely.
The rate of growth and weight gain is unique for each child.. In the first year of life, children develop in leaps and bounds. For example, during the period of introducing complementary foods, the baby’s weight may not reach the “norm” due to adaptation to a new type of food, and not because of pathology.

This does not mean that deviations from the norm should be ignored, but it is better to regard them as a reason to pay attention and consult with a specialist in order to identify possible problems with health, or make sure that they do not exist.

What can cause obvious deviations from the norm?

Previously, we talked about minor deviations from the norm and the fact that there is no need to be alarmed if your child grows and gains weight not strictly according to the table. But what to do if the essential values are outside the acceptable parameters, or are they at the intersection of normality and pathology?

The reasons for possible deviations can be divided into two groups:

1. Non-endocrine:

Constitutional growth retardation. Or in other words, late puberty syndrome. One of the normal variants is when the pubertal leap occurs later than in other children.
Familial short stature. It has a hereditary predisposition; in the family of such children there are relatives with short stature. Growth retardation manifests itself from early childhood.
Prematurity, intrauterine and postpartum trauma.
Genetic syndromes. As a rule, they have many clinical manifestations, one of which is growth retardation.
chronic diseases cardiovascular, bronchopulmonary systems, gastrointestinal tract, as well as anemia.
Starvation.
Taking certain medications.

2. Endocrine:

Growth hormone deficiency. Biologically active substance, which is the main regulator of the growth process after 2 years.
Lack of thyroid hormones. Most often of a congenital nature, clinically characterized by delayed physical and intellectual development from birth.
Type 1 diabetes. A disease in which, due to insulin deficiency, the supply of glucose to the body’s cells is disrupted, the so-called. “starvation” of cells, as a result, growth rates slow down.
Itsenko-Cushing's disease (or syndrome). At the same time, the production of hormones of the adrenal cortex - glucocorticoids, which in large doses leads to disruption of the secretion of growth hormone, is increased.
Rickets. A lack of vitamin D leads to bone destruction and skeletal deformations, which in turn is manifested, among other things, by a decrease in growth.
Other rare endocrine system disorders.

As you can see, there are quite a lot of reasons.

If a child's growth is delayed, parents should consult a doctor to identify the causes of short stature and promptly correct it.

Remember that for normal growth of a child, a complete, balanced diet with a sufficient amount of vitamins and microelements, as well as dosed physical activity, is necessary.
