Height Calculator
Estimate a child's adult height from both parents' heights.
Predicting a child's adult height uses parents' heights in a formula developed from population growth data — a rough estimate, useful for general planning rather than a precise prediction.
Why this comes with a wide margin of error
This mid-parental estimate has a typical margin of roughly ±8.5cm — genetics play a large role in height, but so do nutrition, health, and other factors during childhood that this formula can't account for.
Frequently asked questions
How accurate is this prediction?
It's a reasonable population-level estimate but not precise for any individual child — a pediatrician using growth charts and bone age assessment gives a far more accurate individual prediction.
Does this account for growth spurts or late bloomers?
No — it's a simple calculation based on parental height alone, not individual growth patterns.
