Overview
The Child Predicted Height Calculator estimates a child's adult height and range from the parents' heights using the mid-parental height method. Final height is strongly influenced by genetics, and this method applies a sex adjustment (±13 cm) to the parents' average height. Results are shown as a central estimate with a range of about ±8.5 cm, useful as a reference for growth tracking and goal-setting.
Formula
Boys = (Father's height + Mother's height + 13) ÷ 2 Girls = (Father's height + Mother's height - 13) ÷ 2 Range = Predicted height ± 8.5 cm
How to Use
- 1Enter the father's height (cm).
- 2Enter the mother's height (cm).
- 3Select the child's sex (boy or girl).
- 4View the predicted adult height and ±8.5 cm range.
Tips
- ✔The mid-parental method is a genetic-only statistical estimate; actual height may fall outside the range.
- ✔Adequate sleep (growth hormone is released during deep sleep), balanced nutrition, and regular exercise support growth.
- ✔If growth is markedly slower or faster than peers, consider a pediatric consultation for growth-plate or hormone evaluation.
- ✔The timing of puberty can change the final height.
FAQ
Q. How accurate is the mid-parental method?
As a parents-only prediction, most children fall within about ±8.5 cm (2 standard deviations) of the estimate. It does not account for nutrition, sleep, exercise, or puberty timing, so use it as a reference.
Q. Can a child grow taller than predicted?
Yes. The method reflects only a genetic tendency; with good sleep, nutrition, and exercise, a child can reach the upper end of the range or beyond. Poor conditions can keep them at the lower end.
Q. What is the 13 cm sex adjustment?
It reflects the average adult height difference between men and women (about 13 cm). It is added for boys and subtracted for girls to adjust the final-height tendency by sex.
