Want to know how tall your child will be as they grow older? Use this calculator to find out your child's expected adult height and to estimate your child's future height potential. Taller stature has been linked in many cultures to increased social status, hence most parents are eager to know how tall their child will grow to be. 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 that DNA sequence variants determine about 80 percent of an individual's height. The other 20 percent is influenced by environmental factors and also on the nutritional status of the mother during pregnancy().

However, predictions can never be always accurate. In an interview, Professor Tim Frayling, who was involved in a large study on this subject, said, "It's common knowledge that people born to tall parents are more likely to be tall themselves."

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().

No matter what the outcome is, the paramount objective is to ensure the child's happiness, activity level, and health to foster their full life potential. This will also contribute to the child's height development.

Interesting Must Know Facts about Future Height of Child

Many parents are interested in knowing how tall their child will grow to be, as taller stature is often associated with increased social status in various cultures.

Predicting a child's future height and the factors that contribute to it can be a a bit complicated. Listed below are some interesting facts that can help you understand this subject better.

Formulas to predict Child's future height -

There are several formulas available that can estimate a child's future height by considering the height of both the mother and the father. Despite the availability of prediction formulas, it's important to note that predictions may not always be accurate.
Professor Tim Frayling, who participated in a significant study on this subject, mentioned that it's commonly known that children born to tall parents are more likely to be tall themselves.
It is believed that in adulthood a male child will be twice the height he was at 24 months. A girl will grow to be twice the height she was at 18 months. This is only an approximate calculation and not an accurate prediction(3^✔ ✔Trusted Source

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.

Role of Genetic & Environmental Factors in determining future height of the child

The height of a child is largely determined by genetics, with approximately 80 percent being attributed to DNA sequence variants. Environmental factors and the mother's nutritional status during pregnancy contribute to the remaining 20 percent of a child's height.
Non-genetic or environmental factors that determine the growth and height of a child also include the mother's nutritional status during pregnancy and habits like smoking or the use of hazardous substances(4^✔ ✔Trusted Source

Puberty and Spurt in Height

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(6^✔ ✔Trusted Source

By what age does the child stop gaining Height?

Generally, most boys reach their maximum height potential by the age of 16 to 17, while girls typically reach theirs by 14 to 15. These ages signify the end of puberty.
It is highly unlikely for individuals to gain significant height after the age of 19.

Influence of Nutrition on the Final Height of a Child

Nutritious food is an important determinant for the final height of a child. A child who is well-nourished and active is likely to be taller than a child on a poor diet(7^✔ ✔Trusted Source

Do Exercises Help in Increasing Height?

Generally physical activities and exercises are the best way to keep your child active and healthy. However there is no evidence that activities and exercises like hanging, climbing or swimming can increase height.

Role of Growth Hormone injections to Improve Height of Child

Growth hormone injections can help stimulate growth and increase height in children who have a documented Growth hormone deficiency (GHD) of these hormones. Mostly it can be genetic factors or certain medical conditions like Turners or chronic kidney diseases in a child or the cause maybe unknown(9^✔ ✔Trusted Source
