            Understanding Child Height Predictor

            Estimate adult height from parents' heights. Within health calculators, child height predictor belongs to the body composition cluster, where it shares terminology and assumptions with closely related tools.

            Learning how child height predictor is calculated

            The mid-parental method predicts adult height within roughly ±8.5 cm. Working through the variables one at a time — M, F — makes the result reproducible by hand and easier to sanity-check.

            Using child height predictor to make a decision

            Because outputs depend on the assumptions you enter, run more than one scenario before committing to a figure.

            How child height predictor compares with related measures

            fat mass, lean mass, adiposity, percentile all describe adjacent aspects of body composition. Comparing this calculator's output against those measures — using the related tools listed on this page — prevents a single metric from being read in isolation.
