Child Height Predictor API
Predicted-adult-height maths as an API, computed locally and deterministically. The midparental endpoint applies the Tanner mid-parental method — for a boy (father + mother + 13)/2 and for a girl (father + mother − 13)/2 in centimetres — and returns the target height together with the ±8.5 cm range within which most children fall. The double endpoint uses the well-known rule of thumb that a child's adult height is about twice their height at age two. The remaining endpoint takes a child's current height and a predicted adult height (given directly or worked out from the parents) and returns the remaining growth and the percentage of adult height already reached. Everything is computed locally and deterministically, so it is instant and private. Ideal for parenting, paediatric and family-health app developers, growth-tracking and milestone tools, and wellness dashboards. Pure local computation — no key, no third-party service, instant. Live, nothing stored. Population estimates with wide individual variation — not medical advice. 3 endpoints. This is adult-height prediction; for BMI and body composition use a BMI API.
