Want to know how tall your child will be as they grow older? Use this calculator to find out your childs expected adult-height.
Most parents are eager to know how tall their child will grow to be. Taller stature has been linked in many cultures to increased social status. There are many formulas that can predict the future height of your child by taking into consideration the height of the mother and the father.
To a large extent the height of your child is genetically determined. It is estimated DNA sequence variants determine about 80 percent of an individuals height. The other 20 percent is influenced by environmental factors and also on the nutritional status of the mother during pregnancy.

However, prediction can never be always accurate. In an interview Professor Tim Frayling who was involved in a large study on this subject said, Its common knowledge that people born to tall parents are more likely to be tall themselves, nevertheless he added, But Im surprised how complex the picture is. This goes a long way to fulfilling scientific curiosity that could have real impact in the treatment of diseases that can be influenced by height, such as osteoporosis or cancer.
Most boys reach their full height potential by the age of 16 to 17 years and girls by 14 to 15 years. This age marks the end of puberty. After 19 years chances of gaining any height would be very unusual.
Use this calculator to estimate your child's future height potential but ensure that the child is happy, active and healthy to attain their full potential in life and this will also help the child to grow tall.

Interesting Top Ten Facts About Height
- The rare condition that causes short stature called achondroplasia is due to defect in genetics and caused by mutation in the FGFR3 gene.
- It is estimated that there are more than 700 gene variants that determine the height of an individual.
- Growth of the long bones of lower limbs is primarily responsible for the spurt in height during puberty. At the end of puberty the hormones close the growth plates in the long bones.
- It is believed that in adulthood a male child will be double the height he was at 24 months. A girl will grow to be double of the height she was at 18 months. This is only an approximate calculation and not an accurate prediction.
- Another way to predict height is to take the average height of the parents and then, for boys add 2.5 inches or 6.5cm and for girls subtract 2.5 inches.
- Nutritious food is an important determinant for the final height of a child. A child that is well-nourished and active is likely to be taller than a child on a poor diet.
- Eggs are a good source of protein. Studies in developing countries have shown that children who are regularly fed with at least one egg a day are taller than children who do not get this daily nutrition.
- In developing countries it has been estimated that poor nutrition and hygiene cause an estimated 145 million children under age five to have stunted growth.
- There is no evidence that activities like hanging, climbing or swimming can increase height.
- Non-genetic factors that determine growth and height of a child also include the mothers nutritional status during pregnancy and habits like smoking or use of hazardous substances.

Curious to find out how tall your child will be when they grow up? We can't see the future, but with a little math and science, we can make a pretty good guess about how tall they'll be when they're 18 – with a margin of error under 2 inches.
This calculator works for children age 2 and up. (Depending on your child's age, we'll use some or all of the information you entered in our calculations.) You may get inaccurate results for children who are exceptionally tall or are already taller than both their parents.
The Height Predictor is meant to be a fun tool, and doesn't guarantee your child will be this height when they grow up. If you're concerned about your child's growth, talk to their healthcare provider.
How to tell how tall your child will be
There are a few different methods of predicting how tall your child will be when they grow up. Our Child Height Predictor tool uses the Khamis-Roche method, which is based on a study conducted in the 1990s with about 400 participants.
The method takes a child's height, weight, and the average height of their parents, then uses ratios to determine how to calculate the child's predicted height at age 18. A previous method also used the child's skeletal age, which is how mature a child's bones are and requires an X-ray. But the Khamis-Roche researchers wanted to find a way parents could predict their child's height without having to get an X-ray taken.
If you want to test out other ways to predict your child's height at home, these are a couple methods you can try:
Two years times two
Children grow a ton in their first few years of life – in fact, their first growth spurt from baby to toddler accounts for about half of their adult height. One simple way to predict how tall your child will be when they grow up is to take their height at age 2 if they're a boy or 18 months if they're a girl and double it. (Girls grow a little faster than boys.)
This method has been around for a long time, but there isn't any scientific research about how accurate it is.
Mid-parental method
Another way to estimate your child's adult height is to add together the height of both parents and divide it by two.
Then, some methods say to add 5 inches if they're a boy and subtract 5 inches if they're a girl; others say to only add or subtract 2 ½ inches. There's a high margin of error with this method – it could be off by 4 inches.

How to find out how tall a child will be when he grows up: calculator and growth rates

pediatrician
In the first year of life, children literally grow by leaps and bounds hours and grow 25 centimeters by their first birthday. Growth hormone is produced in the endocrine gland, which is located in the brain. This happens when the baby is sleeping, which is why healthy and restful sleep is so important.
“From one to three years old, a child on average gains 10 centimeters a year,” says pediatrician Marina Fedyushina. - From three to six years, the growth rate decreases: the mark on the stadiometer increases by about 4-5 centimeters. Until the age of 10, there is a slight slowdown, and already from the age of 11 (for girls) and from 13 years (for boys) there is a sharp jump in growth rates. After 40 years, we begin to decrease a little. This is due to fluid loss from the intervertebral discs.”
Place of birth matters
Obviously, growth is due to heredity. It is the genes that determine whether your son will be teased by Gulliver, and your daughter by Thumbelina. Not so simple.
“In 2014, American scientists conducted a large-scale study on the influence of genes on human growth,” says Doctor of Biology Antonina Volkova . - The project was carried out by specialists from 300 institutes, and the number of participants reached 250 thousand people. The experiment proved that human growth is influenced by various gene variations, and there are about 300 hundreds of them. It is important what were your ancestors (not just parents), from whom you got a certain appearance.
The scientists also found out that the northerners are much taller than the inhabitants of the southern regions. For the first time, the German biologist Karl Bergman told the world about this, he said that a hot climate contributes to a slowdown in growth processes.

Growth Formulas
Doctors have come up with a few simple formulas that can be used to predict where in the ranks your child will stand in physical education classes.
1. The most common formula
Boy height (cm) = (Mother's height + Father's height) * 0. 54 - 4.5 (cm)
Example: (165 + 183) * 0.54 - 4.5 (cm) = 183 .4 (cm)
Girl's height = (mother's height + father's height) * 0.51 - 7.5 (cm)
Example: (159 + 173) * 0.51 - 7.5 (cm) = 161.8 (cm)
2. Dr. John Hawker's formula
An employee of one of the largest private medical centers in the world, the Mayo Clinic, proposed the following calculations:
The boy's height is = (Father's height + Mother's height): 2 + 6.4
Example: (183 + 165): 2 + 6.4 (cm) = 180.4 (cm)
Girl's height = (Father's height + Mother's height): 2 - 6.4
Example: (173 + 159): 2 - 6.4 (cm) = 159.6 (cm)
Boy's height = (Father's height + Mother's height * 1.08): 2
Example: (183 + 165 * 1.08): 2 = 180.6 (cm)
Girl's height father * 0.923 + mother's height): 2
Example: (173* 0.923 + 159): 2 = 159.3

4. The Smirnov-Gorbunov formula
The authors of the sensational article "Short stature in childhood" Professor Vladimir Smirnov and endocrinologist Gleb Gorbunov also wondered what height a child would have in adulthood. This formula allows an error of as much as 8 cm:
Boy's height = (Father's height + Mother's height + 12.5): 2 ±8
Example: (183 + 165 + 12.5): 2 ±8 = 188.25 (cm) or 172.25 (cm)
Girl's height = (father's height + mother's height - 12.5): 2 ±8
Example: (173 + 159 - 12.5): 2 ±8 = 167.75 (cm) or 151.75 (cm) )
5. The formula for the growth of a child per year
According to the World Health Organization, the normal height of a one-year-old boy is considered to be from 71 to 80.5 cm, for girls - from 68.9 to 79.2 cm. If you want to know what will be your baby by the age of 20, it is necessary to add 100 cm (for a boy) and 95 (for a girl) to the height that the baby reached at 12 months.
Based on this formula, boys can only grow to 180. 5 cm and girls to 174.2. How then to be with Ivan Urgant, who has reached a height of 195 cm?
Professional sports can also change appearance. If you don’t want a modeling career for your child, then feel free to give it to gymnastics: a serious load on the joints and bones, spinal injuries contribute to problems with the development of the skeleton, children grow poorly. Although the famous gymnast Laysan Utyasheva has grown to 167 centimeters, this is quite a normal height for a girl. But swimming, football, hockey, tennis, volleyball will allow you to become taller, faster and stronger.
Pediatricians themselves do not particularly trust these methods of calculating height.
“There will always be errors,” continues Marina Fedyushina. - The growth rate, in addition to heredity, is influenced by various factors. First of all, this, of course, is the state of the endocrine glands. Do not discount nutrition and lifestyle. Lack of vitamins, smoking and alcohol slow down the growth of the child”

Admit it, you want to know how your baby will grow up? Looking into the future is always interesting. Specialists came to the aid of parents: pediatricians and mathematicians. Now, after all, scientists can predict anything, except, perhaps, the weather.
All together they have compiled several formulas by which you can calculate how tall your baby will reach for years, that way, by the age of 18-20. We have tested all these formulas. And here's what we got.

Method No. 1: formula of the 70s
Everything is simple here. This method of calculating growth has been used since the 1970s. All you need is to know the height of the parents. To calculate the height of a girl, the formula will look like this: dad's height + mom's height -13 and divide the result by 2. For a boy, it's exactly the same, but you don't need to subtract 13, but add.
So, let's check. Natasha's example: dad's height is 184 cm, mom's height is 164 cm. see, getting out of all the forecasts.

Misha's example. Mom and dad are 165 and 176 cm respectively. We calculate: 165 + 176 = 341. Plus 13 - we get 354. Divide by two - 177 cm. But Misha ruined everything, reaching up to 196 cm ( read also : How to dress a plump woman of small stature - these tips will come in handy for everyone).
An example of Tolya. Yes, Misha's example is still not entirely indicative, we agree. Therefore, we also took Tolya - he is more human in growth. The height of his mom and dad is 165 and 187 cm. Substitute in the formula, we get the result - 182.5 cm. Surprisingly accurate - Anatoly's height is 183 cm.
Method #2: magic factor
For this formula, you also need only the height of the parents. To find out the height of the boy, the height of mom and dad in centimeters must be added and multiplied by a factor of 0.54, and subtract 4.5 cm from the result - this is for boys. In the case of a girl, the coefficient will be equal to 0.51, and more must be subtracted from the result - 7.5 cm.
We consider. Natasha's example: (164 + 184) x 0.51 = 177.48. We subtract 7.5 cm - it remains almost 170 cm. The discrepancy with reality was 10 cm.
Misha's example. 341 × 0.54 - 4.5 = 179.6. Hm. Apparently, Mikhail, with his monstrous growth, broke all the conclusions of mathematicians.
An example of Tolya. 352 x 0.54 = 190.08. We subtract 4.5, we get 185.58. Almost grown. Method #3: Hawker's formula The bottom line is this: you need (of course) to add up the height of mom and dad, divide by two. If you are calculating the height of a boy, add 6.4. In the case of a girl, subtract all the same 6.4.
Natasha's example. 348/2 \u003d 174. Subtract 6.4 - it turns out that Natasha should not have grown above 167.6 cm. But she grew up ( read also : The most attractive female height and weight according to men).
An example of Tolya. Yes, we decided to abandon Misha because of his Uncle Styopa syndrome. Anatoly's mom's height is 165 cm, dad's is 187. We count: 165 + 187 = 352. Divide by 2: 176. Plus 6.4 - we get 182.4. Bingo! Recall that Anatoly's height is 183 cm.
Method No. 4: Karkus formula
Here the method of calculating the final height of a boy and a girl is slightly different. Let's start with Natasha. The formula prescribes to multiply the father's height in centimeters by a factor of 0.923, add the mother's height to the resulting number, and divide the total amount by two. We consider: 184 × 0.923 \u003d 169.832. Plus mom's height: 333.832. We divide everything by two: 166.9 cm. Again, by.
Now let's take care of boy Tolya . It’s simpler here: the sum of the growth of mom and dad needs to be multiplied by a factor of 1.08, the result is divided by 2. It turns out 190 cm. They didn’t hit - they overestimated the height of our test subject by 7 cm. I wonder if this method will work with Misha? Let's try. We add, multiply, divide - it turns out 184 cm. It didn’t work out.

Method No. 5: allowable error 183.
Natasha's example. To calculate the girl's height, the formula prescribes to add the height of the father and mother, subtract 12.5 cm from the sum, and divide the result by two. The result will be the final height of the child, plus or minus 8 cm. We consider: 164 + 184 - 12.5 = 335.5. We divide by two, it turns out 167.8. Even if you add 8 cm of error, you can't reach 180.
An example of Tolya. Boys are calculated a little differently. Again, we add the height of mom and dad, but we add 12.5, and do not minus. It turns out 364.5. Divide by two - 182.3. Right on the bull's-eye, without any errors.
Method No. 6: growth of a child per year
We don't need either mom or dad here, only the growth of a baby at the age of 12 months. To calculate the girl's height, you need to add 95 cm to it. In the case of a boy, you need to add 100 cm.
Natasha's example. Our girl was 69 cm tall a year. It turns out that according to this formula, she should not have grown above 164 cm. But she did.
An example of Tolya. Our boy at 12 months reached the mark of 71 cm. And, it turns out, he outgrew the forecast by as much as 12 cm.

Method number 7: purely mathematical
We will not torment you with the justification of this formula, it was deduced by highbrow mathematicians. Yes, and it doesn't matter. The main thing is to understand if the method works. This is what we'll do.
An example of Natasha. Mathematicians propose to calculate the girl’s height according to the formula: mom’s height + dad’s height, multiply the amount by a factor of 0.505, and subtract 5 cm from the resulting number. We count: 164 + 184 = 348, multiply by 0.505 - we get 175.7. Almost. But after all, it is necessary to take away another 5 cm. As a result, we get a miserable 170.7 cm. We did not reach it a little.
An example of Tolya. We evaluate the growth of the boy a little differently. The coefficient will be equal to 0.57, and from the final number you need to subtract not 5 cm, but as much as 14 and a half. We consider: 165 + 187 \u003d 352. Multiply by 0.57, it turns out 200.64. Subtract 14.5 - we get 186 cm with a small tail. Very close!
It is worth remembering that a lot of things affect the growth of a child: from nutrition to sports.
