Weight-for-Length Percentile Calculator (0-2 years)
Calculates weight-for-length/height percentile for infants 0-2 years using WHO MGRS growth charts to assess body proportion.
Age in months (0-24 months)
Current weight in kilograms
Recumbent length (<2 years) or standing height (if measured standing, add 0.7 cm)
Sex for percentile lookup
WHO recommended for international use; CDC for US
⚠️ Warnings & Contraindications
- WHO weight-for-length charts are preferred for infants 0-2 years
- Standing height is approximately 0.7 cm less than recumbent length
- For children >2 years, use BMI-for-age instead of weight-for-length
- Rapid crossing of percentile lines may indicate nutritional problems
- Premature infants should be plotted using corrected age until 24 months
ℹ️ Clinical Notes
WHO charts are based on the MGRS (Multicentre Growth Reference Study) of healthy breastfed infants. Weight-for-length is the preferred indicator of acute malnutrition in children under 5 years globally.
