A newborn baby's head grows every month. Accordingly, its circumference changes. Not only by weight, height, chest girth, but also by the circumference of the baby's head, doctors determine how it develops. A very large or very small head size may indicate pathology (hydrocephalus or microcephalus). If the child has minor deviations from the norms, then, most likely, this is due to a genetic predisposition.
After the baby is born, doctors immediately measure its parameters in the delivery room, including the volume of the baby's head. This value is compared with the chest circumference of the newborn. If immediately after the birth of a child his chest is less than the head by 2 centimeters, then by four months these indicators are almost equal. And at 12 months, the baby's chest circumference is already about 2 centimeters larger than the head parameter.
Head circumference immediately after birth is on average 34–35 centimeters. The girth of the chest is 32–34 centimeters. In the first 3 months, the newborn's head grows rapidly. At 4 months, its circumference is approximately 40-42 centimeters. The head circumference should increase from one and a half to two centimeters every month. The ribcage of a small child also grows rather quickly. In relation to the chest, the child's head does not add so rapidly after three or four.
Calculation by formula and tables with average values
Mom and Dad can independently measure their child's head circumference. A calculation using a special formula will help determine the rate. Focus on half a year. The head circumference of a child by this age is approximately 43 centimeters on average. To make a calculation, for each previous month, 1.5 centimeters must be subtracted from this number. The calculations will be approximate. And the parameters for girls and boys will differ due to physiological characteristics.
Formula. For example, the head circumference of a four-month-old baby is 40 centimeters. We got this figure like this: 1.5 was subtracted from 43 and 1.5 more. After 6 months, the formula will change. It is necessary to add 0.5 centimeters for each month.
Further - tables, which indicate the average values \u200b\u200b\\ u200b \\ u200bof head circumference and chest circumference for boys and girls aged 1 month to one year. Please note that these parameters are not suitable for measuring the head of premature babies. In such children, the head and chest grow more slowly.

What are the deviations from the norm
If there are deviations from the norm when measuring the head circumference, but in relation to the rest of the indicators this parameter is normal, then the baby has no pathology. Perhaps the child's parents had a small or large head. The main thing is that the head circumference indicator should not be more than the chest parameter, except for the time when they should be the same.Deviations from the norm may be as follows:
- If the baby has a very large head with a forehead that protrudes, with large convex fontanelles, and there is a venous mesh, then these are signs of hydrocephalus. With such a disease, fluid accumulates in the child's brain.
- If a child has a very small head with a small forehead, closed fontanelles and there are abnormalities in neurology, then these are signs of microcephaly.
Babies with hydrocephalus or microcephaly feel less well. The appearance of children is changing. The above pathologies are determined using ultrasound. And they need to be treated.
How to measure your head and chest
You can measure the head circumference of children with a measuring tape. It should pass through the bump at the back of the head, then through the brow ridges. To measure the ribcage, you need to skip a centimeter at the level of the nipples, and then behind the shoulder blades (at their lower corners). The baby's head and chest should be measured when he is calm. The child should not cry, strain.
If the head of a newborn baby in relation to the body looks disproportionate, then this is a normal situation. As they grow up, the proportions become equal.
Often, parents are concerned about the question of whether their small size and shape are correct. And some parents, on the contrary, do not think about this question. Although in fact it is worth being interested in this.
Let's figure out what it is for and find out about the generally accepted ones, breaking them down by age.
Why do this
Infant head circumference - an extremely important indicator of it and.
Along with the size of the child's head, it often indicates the presence of different ones, because it is located in the skull, which gradually (by months) gains mass. 
How to measure a circle correctly
From birth, the baby's head circumference is measured every week, recording the results and checking against the month. It is better to let the same person do it, and at the same time be calm, in a good mood.
Place the centimeter on the most prominent points of the skull, on the frontal and occipital tubercles. It is also necessary to measure the crumbs, as it grows parallel to the skull.
In order not to injure the baby, do not forget about the safety rules. It is important to remember that the vagus nerve, which is responsible for most bodily functions, runs near the back of the head. With its displacement, serious problems are possible: from digestive diseases to motor disorders.
Important! Raise the little one gently, supporting the head. Under no circumstances do this by the handles orbehindhangers!
Norms of head volume in children (table)
Of course, children have different norms for head volume, which is shown in detail in the table below.

Is it worth worrying and what to do in case of deviations
If the volume of the head of the crumbs does not correspond to the indicators of the norm, even taking into account possible fluctuations, this is a cause for concern and a mandatory reason for going to a specialist.
There are several main reasons for this:
- Heredity. If one of the parents or close relatives has a head more / less than the norm.
- Birth injury. By the way, in babies who were born through a cesarean section, the shape of the head is closer to normal.
- Congenital pathologies. For example, or microcephaly.
As you can see, the size of the head in children is a very important point in theirs.Therefore, be sure to take the necessary measurements, writing them down and looking at the table. Seeing possible deviations, be sure to consult a doctor. When it comes to the health of your baby, no extra precautions are needed.
At birth, and then every month during a routine examination, the pediatrician will certainly measure the head circumference of a newborn baby. Along with other parameters (height, weight, chest girth), this one plays an important role: it can be used to judge the pace and norms of the baby's development. A very large or very small head of a baby often indicates the development of pathology - hydrocephalus or microcephaly. But, as a rule, the deviation from the norm of this indicator is a genetically determined physiological feature of the child.
So that parents do not have unnecessary worries about this, let's study this issue together today.
Baby head circumference: norms
The first measurements are taken immediately at the birth of the baby. This indicator averages 34-35 cm. During the first year of life, the baby's head will grow rapidly, increasing by an average of 12 cm by the end of 12 months.
The most active period of growth of the baby's head is the first quarter: by 3-4 months, the baby's head circumference will be 40-42 cm (in each of these months, 1.5-2 cm is added). Around this time, it will become equal to the circumference of the chest, which increases even more intensively. Then, gradually, the growth in the size of the head will slow down slightly compared to the growth of the chest, and in the future, until the end of life, normally the human chest remains larger in volume than the head.
In order to assess the rate and rate of development of a newborn by the volume of its head, there is a simple formula for calculating the "normal" head circumference of a one-year-old child. A 6-month age is taken as a reference point, in which the average head circumference is 43 cm.To determine the norm in any of the previous months, subtract 1.5 cm for each of them.
- Example: in 4 months, the average head circumference of a baby is 40 cm (43– 1,5– 1,5=40).
To determine what is the norm of this indicator for a child after the age of six months, 0.5 cm should be added to 43 cm for each month after 6.
- Example: in 9 months old baby's average head circumference is 44.5 cm (43+0,5+0,5+0,5=44,5).
The described method allows you to approximately calculate the head circumference of a one-year-old child. But, in addition, there are established norms for this indicator for children of different ages, and separate for boys and girls, since the physiological parameters of children of different sexes are slightly different.
In premature newborns, the head size is usually less than the average, and begins to actively increase later than in full-term babies - during the period of intensive weight gain.
Newborn baby head circumference: abnormalities
It should be said that this indicator is always evaluated in conjunction with others, and together they determine the norms of growth and development of the newborn. In addition to the fact that such measurements do not carry diagnostic information, if considered separately, deviations from the established norms in some cases can also be a variant of the norm.
For example, if one of the parents in childhood (or even in adulthood) had a small or large head, then the child may also have such a physiological feature. The most important thing is that it does not exceed the circumference of the chest, except for the period when they are compared with each other.
Nevertheless, if the indicators of the child's head circumference differ significantly from the accepted average norms, then you should take a closer look at his appearance. An excessively large head, along with other clinical signs (large convex fontanelles, diverging sutures, a large protruding forehead, the appearance of a venous network on the head, severe neurological disorders, etc.) may indicate the development of a serious pathology - hydrocephalus, in which fluid accumulates in the brain. A very small head, together with other characteristic symptoms (small or closed fontanelles, a small "sloping" forehead, neurological disorders, etc.) indicates the development of microcephaly. Both of these pathologies require compulsory treatment by a specialist. The diagnosis can be refuted or confirmed by ultrasound.
How to correctly measure the circumference of a child's head?
In order not to get lost in false assumptions, the head circumference of a newborn baby must be measured correctly. To do this, the head is wrapped in a soft centimeter tape with divisions, passing in front along the line of the eyebrows, and behind - along the occipital protuberance. A prerequisite for obtaining reliable measurement results is the emotional calmness of the baby: if he cries or screams, then the data obtained will be inaccurate.
Do not be confused by the size of the newborn's head: it always looks disproportionate to the size of the body.
But as the child grows, the proportions will level out and take on a form familiar to the adult eye. If a child develops any pathological condition, the doctor (and attentive parents too) will be able to immediately determine this by his appearance and well-being: hydrocephalus and microcephalus are immediately noticeable, or, if the hydrocephalic syndrome is just beginning to develop, the head circumference increases sharply compared with previous indicators.
Especially for - Ekaterina VLASENKO
The child's weight gain and height standards have been established by the World Health Organization (WHO). But in 2006, WHO revised and issued new international standards for increase. This was due to the fact that previous data were developed more than 20 years ago, and they relied mainly on babies who eat artificial mixtures. But, as practice shows, babies fed on breast milk gain weight more slowly than babies fed on formula. And according to the WHO, this situation could provoke unreasonable recommendations for supplementary feeding with mixtures, overfeeding, and subsequently possible obesity in such babies.
The new standards represent the correct ratio of development in childhood for all parameters of the baby and can be used for all babies, regardless of the type of feeding.
Weight gain of the child.
In the first months of life, the baby usually grows at a rapid pace, adding about 600-800 g per month. Further, starting from about the second half of the year, weight gain slows down a little and with each subsequent month it decreases by about 50g. Also, an indicator of correct weight gain is the fact that by about 5-6 months the baby's weight should double, and by the year it should triple. In addition, +/- 10% deviation from these values \u200b\u200bis normal.

Increase in height of the child
According to statistics, the normal growth rate of a newborn baby is considered to be from 48 to 56 cm, and the average height according to the same statistics is 50-52 cm. It is important to know and understand that growth in itself does not mean anything, and when evaluating a baby, you need to focus on the ratio of weight to height of the newborn, and not on height alone.
During the first year, the baby grows at a very active pace, but it should also be noted that the child can grow unevenly, in jumps, either in weight or in height. Sometimes seasonal phenomena are also noted, in the spring and summer babies grow up faster, and in the fall and winter they gain more weight.

Head circumference of a child up to a year
Also, your pediatrician, in addition to weight and height, is also interested in other indicators - head and chest girth. The correct ratio of these parameters in each specific month indicates the harmonious development of the baby. Until about 3 months, the baby's head grows faster than the chest (an indirect sign of brain development), after which the growth rates are compared, and already from about 5-7 months, the chest begins to gradually outstrip the head growth rate.

All the data given in the article are approximate, because each child is individual and grows according to his own schedule laid down by nature, and, accordingly, the rate of weight gain and growth of the child may differ from the indicated parameters.

To buy or sew a hat for a baby or schoolchild, you need to know the parameters of his head. It depends on the accuracy of their measurement whether a new thing is suitable for a young fashionista, and whether he wants to wear it. The necessary measurements are taken, armed with a measuring tape. If this is not possible, for example, when a hat is bought as a gift, you can determine the size of the head by the age of the child using tables with average values.
How to calculate the size of a hat using measurements
Without the parameters of the baby's head, it is difficult to find a perfectly fitting hat for him. You can "study" the labels on the caps already purchased or use the experience gained when buying hats for the firstborn. But since in newborns the head volume increases by at least 2 cm per month, and in older children - by 5 mm annually, and each baby develops at an individual rate, it is better to determine the size of the headgear according to fresh measurements taken from a particular child.
How to take measurements
To determine the size of a hat for a newborn or a hat for a student, you must measure the head circumference using one of two methods:
- With a centimeter tape. Determine the center of your forehead, attach the end of the tape and wrap it around your head so that it runs over your eyebrows and along the bulging portion of the nape. The number on the tailor's centimeter is the size of the child's head.
- Sewing thread and ruler. Wrap the forehead and back of the head with thread as described above. When both ends of the thread meet in the center of the forehead, cut it and measure it with a ruler, laying it on a flat surface.
How to correlate the resulting figure with the markings on the header
how to determine head circumference
Domestic manufacturers use the simplest and most intuitive dimensional grids of hats for children. The values \u200b\u200bapplied to the hats they sell are equal to the head circumference in centimeters. For three-year-old preschoolers, hats with a tag on the tag 50 are usually suitable, that is, in most cases, the head size at 3 years is 50 cm.
Products of some companies are sewn on a dimensional grid not every 1 cm, but after 2, taking into account only even values: 46, 48, 50. Often there are double markings on hats: 38–40 or 36–38. They indicate that the product is made of a fabric that stretches well, so it fits with both parameters. It's just that in the first case it fits the head tightly, and in the second it is free.
If the label of the cap shows a marking of a paired format, purchase a product with a smaller first number and a suitable second, since the fabric will stretch when worn - and it will fit. It is advisable to choose winter hats for babies with the same first number and a larger second, since they are put on a cap.
Fractional designations are rarely indicated on tags: 36/56, 40/62. The first number is equal to the circumference of the head, the second is the height. An additional indicator helps to orient oneself if the hat is selected taking into account the average parameters typical for children of a certain age, and the child develops non-standard, for example, overtakes peers “in height”. Then you should adhere not to the numbers indicated in the tables of head sizes by month, but to individual parameters.
For example, a half-year-old baby should fit a cap marked 40, since usually the head circumference at this age is 40 cm.But if you check this fact by taking measurements, there is no way, but you are sure that the growth of the crumbs has exceeded 68 cm, then it is better to purchase a product labeled 44/68, not 40/62.
How to determine the size of the head in children by age: tables
On some hats, only the age of the baby is indicated. It is not worth choosing a product for this indicator, since the child's body develops according to an individual scheme. It is better to try on a hat or consult the table of dimensional grids, which manufacturers are guided by to determine the parameters of children by age. For example, at what age is 52 head size.
It should be borne in mind that the head sizes indicated in the tables in newborns and adolescents are inaccurate, since they are average and were determined for children of certain age groups with standard development. But since each child is unique and subject to the influence of genetics, the values \u200b\u200bof the measurements taken from him can differ significantly from the generally accepted ones.

What to do if foreign markings are indicated on the header
The designations on the labels of clothes from Europe and the United States differ from those indicated on Russian things. When buying hats in foreign boutiques and online stores, you should convert domestic sizes to foreign ones using a comparative table.
| Head circumference | Letter mark | England | France | USA |
| 47 | – | 5 | 0 | 5 7/8 |
| 49 | S / M | 6 | 1 | 6 1/8 |
| 51 | XXS | 6 1/4 | 2 | 6 |
| 53 | XS | 6 1/2 | 3 | 6 5/8 |
| 55 | S | 6 3/4 | 4 | 6 |
| 57 | M | 7 | 5 | 7 |
How to make sure the "numbers" on the labels are correct
Size charts used by brands may not match baselines. To make the right choice, inquire if the website has its own table of sizes of hats for children, or search the Internet for the necessary information on the request "Brand Name Size Chart".
You can check whether a hat with an incomprehensible designation is suitable for a child by measuring it. Connect the edges of the product, smooth it and measure the length of the resulting semicircle. Multiply the revealed figure by 2 to calculate the circumference. Add 10 millimeters. The final number is the estimated head circumference.
What to do if the hat didn't fit
Knowing at what age 54 the size of the head, and at what - 56, you can buy or sew a hat without calculating the exact parameters of the baby. If the purchased piece is too small or too small, you can return it to both the online and offline store. The hat is included in the list of goods, the return of which is provided even with indicative quality, if they did not fit in terms of parameters, style or color. But the seller has the right to exchange the product for the desired one, then a refund is possible only in the absence of a suitable hat.To return or exchange an item, three conditions must be met:
- Preserve its integrity.
- Provide a receipt or any alternative document to prove payment.
- Contact the store with a statement about the exchange of goods within 2 weeks from the date of purchase.
The seller may refuse to accept back knitted hats, as well as knitted scarves, shawls, mittens, headscarves, since items of outer clothing made of yarn are included in the list of products that cannot be returned. You can increase it yourself by steaming it from the inside out and stretching it in a warm, damp form. Oversized garments can be easily planted by hand hot washing. And if there is no risk of spoiling the design - and with a machine.
A large wool hat can be felted, but very carefully, otherwise it will be halved or even threefold. Dip it in boiling water, gradually increasing the temperature, until it shrinks "like a tailor-made."
