## How big is my child? The growth calculator

An exciting question indeed! Our growth calculator will give you the answer. Just calculate how big your child will be and see if and how much your child deviates from the average size. You can even calculate the likely size for your unborn baby!

### At a glance

• A child grows fastest in the first year of life.
• Up to its final length, a child will gain an average of three percent in height every year.
• The height of the child depends largely on the height of the parents, but diet and medical care also play a role.
• Today, people are on average around 16 centimeters taller than they were 100 years ago.

All parents want to know: How big will my child one day get? And is it currently too big or too small compared to its peers? Is the size pre-programmed by the parents' genes? And what influence do diet and lifestyle have? We'll provide you with the answers here.

### Growth calculator based on the current size of your child - for all parents

Just enter your child's gender, current age and height of your child. Then click on "calculate" - and you will receive the size that your child is likely to reach. The result will be displayed directly below the calculator!

### Our other growth calculators

Attention: These two additional growth calculators are currently being technically revised and will be available again shortly.

• Growth calculator based on the height of the parents also for parents-to-be
• Percentile calculator How far does your child deviate from the average?

Important: Of course, all calculations do not provide exact values, but only guide values!

### Why is size so important?

Even in the womb, a baby's development is largely judged by its size. Almost every ultrasound has been the brain and the Crown-rump length measured, it continues the same way after the birth: the baby is examined, measured and weighed. And as long as it grows, that doesn't change either. In general, we like to judge healthy development based on body size. And it is precisely the appearance of a person that remains in our memory for a long time: "But you grew up" - how often have we not heard this sentence from relatives and friends even as children? And most parents also know the size and weight of their child's birth even after they have grown up.

### How fast is my child growing?

Until it has reached its final length, a child grows daily - especially at night. Mostly in the first year of life, after which the pace slows down. At school age it is about six centimeters that children put on each year, during puberty there is a significant growth spurt. On average, one can say that a child approaches about three percent more towards his future final length every year.

### Growth calculator based on the height of the parents

Your baby is not even born yet, but you would like to speculate a little how big it will be one day? Our second calculation method is suitable for this: the growth calculator based on the height of the parents, because: Yes, the height of mom and dad also plays a role in length growth.

### Does it all depend on the genes of the parents?

How tall a person becomes in their final length depends 80 to 90 percent on parental genes, says Dr. Beak. In 80 percent of all people who did not grow very tall until adulthood, the reason for the short body length is purely family-related. Only a very small part is really short or tall by definition.

### Percentile calculator - how far does my child deviate from the average?

These curves show how children grow on average. The percentile curve with the number 50 represents the average value in each case. The percentile curves are also shown in your yellow booklet for the preventive medical check-up.

Example 1: At the age of four, your daughter is exactly 1.05 meters tall. This puts it at 50 percentile - exactly on average. 50 percentile simply means that 50 out of 100 girls at this age are taller than 1.05 meters and 50 out of 100 are shorter. For comparison: if your daughter were 1.11 meters tall, she would be at the 90 percentile: 90 out of 100 girls her age would be shorter and 10 out of 100 taller than her.

Example 2: Your son is exactly 1.30 m tall at the age of ten. This puts it exactly at the third percentile. This means that only three out of 100 boys at this age are smaller than or the same size as him and 97 are taller - by definition, children below the third percentile are considered "short stature", above the 97th as "tall stature".

### The late bloomer in the X-ray image

There are very frequent deviations in the ratio of growth to age: of the children who are presented to the hormone specialist for children and adolescents because of short stature, around 65 percent are so-called late bloomers. "The biologically retarded development of growth and puberty is often just a normal variant of growth," said Dr. Dirk Schnabel, pediatric endocrinologist from the Otto Heubner Center for Pediatric and Adolescent Medicine at Charité Berlin. "If the parents themselves later reached puberty as children, they usually pass it on to their children." If there is cause for concern, parents and their child can contact an endocrinologist and have the child's so-called "biological age" (or "bone age") determined. This works on the basis of an X-ray image of the hand bones: The calendar age is simply compared with that of the body and examined for deviations. Such an examination can be carried out from the age of six to seven. Case in point: a 14-year-old boy has a biological age of twelve years. The biological age therefore deviates from the actual age by two years. Is your child a late bloomer? Then you don't need to worry: the "late" will be balanced out soon enough into a "punctual" - the lead time is just a little longer. Absolutely normal!

### What role does physical health play?

The process of growth itself can be inhibited or favored by a multitude of external influences. First and foremost, it is crucial how the child is provided with health care: only if a child can generally grow up under good framework conditions does the organism have the maximum energy available that it needs to grow. This includes good and quick treatment for illnesses in general, prevention of infections and regular vaccinations, a balanced hormonal balance and a healthy eating.
Speaking of which - there has been a lot of improvement in nutrition over the past 100 years: Today's people are on average 16 centimeters taller than in 1905. That's what the statistics from Dr. Beak. He sees the cause of the increase in size mainly in the diet, which is by far higher in protein.

### What role does mental health play?

But physical health is not everything: If mental stability is neglected, it is often also shown physically - and vice versa. To what extent body and psyche actually go hand in hand, Dr. Schnabel on the basis of a study carried out in the mid-1960s: the children of an English children's home were divided into two groups. One group was under an educator who looked after the children very warmly and attentively - the other group, however, was led by a very strict educator. She was very cool towards the children and showed them hardly any love or care, but rather "hard discipline". The result was frightening: While the children in the first group developed normally as expected, the children in the second group literally suffered a "failure" of growth hormones and lagged significantly behind the others in their development. And there was a particular contrast in the growth in length: In contrast to their peers, the children in the second group literally stayed where they were. That this was no coincidence became apparent when the study took a turn: the children in the group with the strict foster mother were transferred to the children in the first group. Within a very short time they made a significant growth spurt and literally blossomed. And: During the medical examination, a sudden release of growth hormones was found!

Your result is "short stature" or "tall stature"?

"Small" and "tall" - that is a definition, not a disease! So that doesn't have to mean anything for the time being. Nevertheless: These children should be presented to the pediatrician. If the parents are very worried or if the child suffers from his or her size, a visit to the doctor can simply calm things down.
