Predicted adult height from bone age
Why bone age and growth tempo matter for predicted adult height, and how Height Predictor applies Bayley-Pinneau tables for clinicians.
Chronological age is not enough
Two kids can share a birthday and sit at very different points in skeletal maturation. Predicted adult height from bone age exists because growth remaining tracks skeletal age better than the calendar alone.
Bayley-Pinneau tables encode that idea: current height plus bone age, split by sex and by whether maturation looks advanced, average, or delayed.
Where Height Predictor fits
Height Predictor is the Swizzle Works iOS lookup for those tables. You bring the bone age. The app brings the tempo-matched table and the predicted adult height.
It will not score the radiograph, invent mid-parental target height, or write your note. It shortens the table step so you can stay with the rest of the visit.
Limits that matter
Bad bone age in, fancy adult height out, still wrong. Measurement quality and clinical context still win. This is clinical decision support, not a diagnosis and not a consumer height oracle.
For the step-by-step input flow, see the Bayley-Pinneau calculator guide. Both sit under the pediatric medicine hub with Pediatric Blood Pressure.
Frequently asked questions
Is predicted adult height the same as mid-parental height?
No. Mid-parental target height uses parental heights. Bayley-Pinneau predicted adult height uses current height and bone age with tempo-specific tables.
Who should use this?
Healthcare professionals evaluating growth with a scored bone age. Not parents diagnosing at home.
Is Height Predictor available now?
It is coming soon on iOS. Join the waitlist from the product page for launch updates.
What bone age ranges are covered?
Supported ranges depend on sex and tempo tables in the app. Check the product page for the current ranges in the shipping build.
