There’s no proven way to predict a child’s adult height. However, various formulas can provide a reasonable guess for child growth. Here’s a popular example:
- Add the mother’s height and the father’s height in either inches or centimeters.
- Add 5 inches (13 centimeters) for boys or subtract 5 inches (13 centimeters) for girls.
- Divide by two.
Most children will reach an adult height within 4 inches (10 centimeters) of this estimation.
