    Child's Estimated Adult Height Calculator

    Curious about how tall your child will be when he grows up? A child’s adult height is determined by many things, including inherited factors, gender, nutrition, and health status during childhood. Although a child’s adult height cannot be predicted with absolute certainty, a number of methods are available for estimating how tall a child will grow to be. One method requires a bone age X-ray. Another method, the Khamis-Roche method used in this calculator, is based on a child’s gender, height, and weight and the height of both parents.

    This calculator is not intended as a substitute for professional health care. Always consult with a health care provider for advice concerning your child’s health.
