How this calculator works

The mid-parental method is a widely used estimate, but actual adult height depends on nutrition, health, and genetics beyond just parental height — real predictions can vary several inches from this estimate.

Formula

boys: (father + mother + 13) ÷ 2 · girls: (father + mother − 13) ÷ 2 (in cm)
