Of course, our calculated values ​​are only mean values ​​based on the data you have entered. They do not lay claim to absolute accuracy, but are only a mathematical approximation to your question “How big will my child get?”.

How does the height calculator for children workr?

Our growth calculator for children takes your child's current data and calculates their average growth per month. The development of the past months and years forms the basis for the extrapolation of the future height of your child.

How big will i get With this formula you can calculate the future height of your child

How big a child becomes depends on the height of the parents. You can therefore calculate an approximate information about the probable height of your child in adulthood with this simple rule of thumb:

Calculate height for boys

Final height of the child =

(Height of mother + height of father + 13): 2

Calculate height for girls

Final height of the child =

(Height of mother + height of father - 13): 2

Can the future size of my child be determined more precisely?

A specific answer to the question "How big will my child get?" can only be given by the doctor in determining the age of the bones. An X-ray of the left hand is taken, which can be used to determine the exact bone age and body height. Without a medical indication, however, this procedure will not be carried out by a doctor. Therefore you have to be satisfied with the approximate values ​​of our growth calculator for children or use the above formula yourself.

However, based on the current height, you can roughly calculate the final height with the help of our growth calculator.

Body size: what role do genes play in growth?

Sure, we know that our size also has to do with our genes. But how much influence does our genetic make-up really have?

  • Up to 90% of our growth is dependent on parental genes. Mom and Dad's genes determine how big your child will grow.
  • In 80% of all short people, the genetic specifications are the reason for the lower body growth. Mom and Dad don't necessarily have to be small. Some genes find their way over generations and detours and only then develop, e.g. B. with a smaller growth in height in the child.
  • About 3% of all in Germany have a height outside the normal range (men up to 167 cm; women up to 153 cm). In the rarest of cases, there is a medical cause.
  • Only about 100,000 in Germany are affected by short stature, e.g. B. a hormone deficiency or a genetic defect. There are 650 forms of short stature.
  • By the way: The average height of men in Germany is 180 cm and women 166 cm.

How can body size be influenced?

Our genes determine how big we can get. But other physical processes can also influence the size of our children. For example, the hormone somatropin is responsible for growth. If there is a disorder in the hormone, your child's growth may be reduced or increased. But getting enough sleep and diet can also affect how growth hormone works. That is why it is especially important for children to get enough sleep, eat a balanced diet and get enough exercise. This is how the hormone can work optimally. So the next time your child asks "How big will I get?" you can answer with a clear conscience: “Big, but only if you sleep enough and eat enough!”.

If there is a proven deficiency in somatropin, which can lead to short stature, the hormone can also be administered artificially. However, this hormonal disorder is relatively rare.

So that you can dress your loved ones appropriately for the weather, we have a few tips for you:

How does a child grow?

Growth in children is particularly rapid in the first few years of life. In the first year of life, for example, babies grow every day, or literally overnight, because most growth spurts happen at night. This is also the reason why growing pains occur mainly in the evening and at night. But here too the development is very individual. So there is no need to worry if your child is smaller than their daycare colleagues - they may catch up with everything again with the next growth spurt.

Differences in growth between children are completely normal. You can check whether your child is an average height for their age in the size chart for babies and in the size chart for children.

How fast is my child growing?

Children grow daily or nightly. Because child growth mostly happens at night when the body is at rest. Especially in the first years of life there is enormous growth in a very short time. After toddler age, the growth curve flattens out over elementary school - growth slows down. Strong growth spurts only occur again after puberty.

How long will my child grow?

In babies, toddlers and elementary school age, girls and boys still grow relatively equally quickly. Significant differences only become apparent towards the end of elementary school age, when children approach puberty. Roughly, one can say that girls grow up to around 15 or 16 years of age and are then fully grown, while the growth phase for boys takes longer. Many boys do not reach their final height until around their 20th birthday.

What's up with the percentile curves?

Percentile curves are available for the child's height and weight. The curves show whether your child is developing normally and healthy - measured against the average. The percentile curves are part of your yellow examination book in which your pediatrician always enters the current value of your child for height and weight during the U-examinations. In this way, possible development delays can be identified quickly. First of all, it doesn't really matter where your child lies on the curve. It is important that its curve continuously increases.
