Child Height Predictor
Estimate a child's adult height from the parents' heights.
A rough prediction of grown-up height
A common way to estimate how tall a child might grow is from the parents' heights, since height is strongly influenced by genetics. This gives that rough prediction, a bit of fun and a general sense of the likely range, based on the well-known mid-parental method.

Genetics guides, but doesn't decide alone
The parent-based estimate captures the genetic influence on height, which is substantial, but it is genuinely rough — real adult height also depends on nutrition, health, and other factors, and there is a wide range around any prediction, so a child can end up noticeably taller or shorter than the estimate. It is best treated as a curiosity and a rough range rather than a firm forecast. A child's growth is tracked far more meaningfully by a healthcare provider against growth charts over time. This is general information, not medical advice; concerns about a child's growth are for a paediatrician or healthcare professional.
Frequently asked questions
How is a child's adult height estimated?
From the parents' heights, using the mid-parental method, since height is strongly influenced by genetics.
How accurate is it?
Rough — genetics guides height but nutrition, health and other factors matter too, and there is a wide range, so a child can end up taller or shorter.
Is this medical advice?
No — it is general information and a curiosity. A child's growth is best tracked by a healthcare provider, and concerns are for a paediatrician.
