Acerca de Child Height Predictor
The Child Height Predictor estimates how tall a child will be as an adult using the mid-parental height method, the screening calculation paediatricians reach for first. Enter the mother's and father's heights, choose the child's sex, and the tool returns a predicted adult height plus the range most children actually land in.
The method averages the two parents' heights and then adds about 6.5 cm for a boy or subtracts about 6.5 cm for a girl — equivalent to the classic version that adds 13 cm to the mother's height for a boy, or subtracts 13 cm from the father's height for a girl. Roughly 95% of children finish within about 8.5 cm (3.3 in) of that target, which is why the result is shown as a range rather than a single number.
It is a genetic-potential estimate, not a measurement. Nutrition, health, sleep, puberty timing and simple variation all move the outcome, and clinicians refine it with growth-chart percentiles or the Khamis-Roche method, which also uses the child's current height, weight and age.
