Bone Age Calculator (Greulich–Pyle) is a growth & development tool commonly applied in Pediatrics. Estimate skeletal maturity from hand and wrist radiographs using Greulich–Pyle standards: match the X-ray to atlas images, enter chronological age, and review bone age versus chronological age with SD-based interpretation. Use the interactive calculator for inputs, limitations, and primary references.

Not a substitute for clinical judgment. Verify critical values with primary literature, local protocols, and specialist input when appropriate.
