Estimate a child’s adult height based on the parents’ heights (mid-parental height).
The Height Prediction Calculator estimates a child’s adult height using the average of the parents’ heights. This method is known as mid-parental height and takes into account the difference between genders.
The calculator is free, works in your browser without registration, and shows the result as soon as you change the values. The calculation is done on your device, and the information you enter is not sent anywhere.
Boy: (father’s height + mother’s height + 13 cm) / 2. Girl: (father’s height + mother’s height − 13 cm) / 2. The range is approximately ±8.5 cm.
Father is 182 cm and mother is 168 cm. The estimated adult height for the boy is (182 + 168 + 13) / 2 = 181.5 cm, or about 182 cm. With default values, the calculator gives the result: Estimated adult height 182 cm.
For parents who are curious about their child’s adult height. It does not replace growth monitoring by a health clinic or doctor.
The range is approximately ±3.35 in, so the result is only a rough estimate.
In addition to genetics, nutrition, sleep, illnesses, and the timing of growth spurts.
If the child's growth significantly deviates from the growth curve, discuss it with a health clinic or doctor.
