Child Adult Height Calculator

Child Adult Height Calculator estimates how tall a child will be as an adult. Enter the child's gender, age, current height and weight, plus the mother's and father's heights, and it returns an expected adult height in feet and inches, or in centimeters.

What you enter
• The child's gender, male or female
• The child's age, up to 18
• The child's current height and weight
• The mother's and father's heights

Where it helps
• A rough idea of final height for a growing child
• A comparison with the growth chart your pediatrician uses
• A conversation starter for parents and families
• Seeing how parents' heights and a child's growth are connected

This is a statistical estimate. Adult height depends on nutrition, health, the timing of puberty and genetics, and can differ from the estimate by several centimeters or inches. Ask a pediatrician for a growth assessment. Light and dark theme, 28 languages. The app is supported by banner ads.
