Child Height Predictor

Estimate adult height from biological parents using two common mid-parental formulas. Supports metric (cm) and imperial (ft+in), and can show boy/girl results together. For family reference only—not a medical diagnosis.

Formulas

1. WHO / mid-parental height (cm)

Boy: (father + mother + 13) ÷ 2
Girl: (father + mother − 13) ÷ 2
Typical range: about ±8.5 cm

2. Midparental Height (MPH) (cm)

Boy: (father + mother) × 1.08 ÷ 2
Girl: (father × 0.923 + mother) ÷ 2
Typical range: about ±7.5 cm

Example: father 178 cm, mother 165 cm → WHO boy ≈ 178 cm (169.5–186.5), girl ≈ 165 cm (156.5–173.5).

What affects height?

Genetics explain roughly 60–80% of adult height differences; nutrition, sleep, hormones, and health explain about 20–40%.

Notes

Use biological parents only—not step or adoptive parents.
This is an adult-target estimate, not a current growth-percentile reading.
More precise options: Khamis-Roche, bone-age X-ray, and CDC/WHO growth charts.

Disclaimer: If you are concerned about short or tall stature, consult a pediatrician.
