Age in months
Standing height (children >2 years) or recumbent length (<2 years)
Sex for percentile lookup
CDC recommended for US children; WHO for international
⚠️ Warnings & Contraindications
- Measure height accurately with stadiometer; measure length in infants with measuring board
- Growth velocity is more informative than a single measurement
- Crossing 2 major percentile lines warrants further evaluation
- Consider mid-parental/target height when interpreting short stature
ℹ️ Clinical Notes
CDC uses recumbent length charts for 0-36 months and stature charts for 2-20 years. WHO uses length for 0-24 months and height for 24-60 months.
