Predicted Adult Height - Bayley-Pinneau Method

Predicts adult height based on current height, chronological age, and bone age using the Bayley-Pinneau method.

cm

Current standing height

years

Actual age in years

years

Bone age from wrist/hand X-ray

Sex for table lookup

⚠️ Warnings & Contraindications

  • Bayley-Pinneau tables are based on normal children and may overestimate in constitutional delay
  • May underestimate in children with growth hormone deficiency
  • Accuracy is best when bone age is between 6-14 years
  • Tables based on Greulich-Pyle atlas; different results with Tanner-Whitehouse
  • Individual predictions have approximately +/- 5 cm error range

ℹ️ Clinical Notes

The BP method uses tables that correlate bone age with percentage of adult height remaining. There are separate tables for normal, advanced, and delayed bone age. The Roche-Wainer-Thissen method is an alternative.
