Bone age and final height calculator
Bayley-Pinneau and multiplier method (chronological and by skeletal age) side by side – with comparison to the mid-parental target height
Calculation aid for healthcare professionals: the calculator reproduces what the sources cited assign to the inputs. Clinical assessment and every treatment decision remain with the treating physician. Inputs and results are not stored.
Frequently asked questions
Bone age and final height calculator: What does this calculator compute?
Presents the adult height predictions according to Bayley-Pinneau (bone age according to Greulich-Pyle) and according to the multiplier method (chronological age; with bone age only as a non-validated additional calculation) side by side without averaging them, shows the maturity category and the bone age gap, and optionally compares the predictions with the mid-parental target height according to Tanner (mean of the parental heights ± 6.5 cm).
