About the Height Calculator
This height calculator converts measurements between centimeters, feet, and inches. It also estimates a child's adult height from their current age, current height, and parental heights. The output is a converted value and an adult height estimate shown in your chosen unit.
The prediction applies the mid-parental height method, which averages the mother's and father's heights and adjusts about 5 inches up for boys or down for girls. Enter the child's age, current height, sex, and both parents' heights in any supported unit. The tool converts measurements automatically, so mixed units work fine. For a reliable estimate, use accurate barefoot measurements, and consult a pediatrician for growth concerns.
