Predict Your Child's Adult Height
Formula
The mid-parent formula is a simple and widely used method to estimate a child's adult height based on the parents' heights. For boys, add 13 cm (5 inches) to the mother's height before averaging. For girls, subtract 13 cm from the father's height.
The prediction has a margin of error of about plus or minus 10 cm (4 inches). Genetics account for 60-80% of height, with nutrition, health, and environment influencing the rest.
Common use cases:
- Estimating a child's growth potential
- Understanding genetic height factors
- Pediatric growth discussions
