Child's Adult Height Tool

Want to know how tall your child will be when he grows up? A child’s adult height is determined by many things. These include his parents’ height, his sex, and his nutrition and health during childhood. A child’s adult height cannot be told exactly. But there are a number of methods for finding out how tall a child will grow to be. One method requires a bone age X-ray. Another method, the method used in this calculator, is based on a child’s sex, height, and weight and the height of both parents.

This tool is not meant to replace a doctor’s care. Always talk with your doctor for advice concerning your child’s health.
