This tool provides estimates based on simplified CDC BMI-for-age tables. It is for educational purposes only and does not constitute medical advice. Always consult a pediatrician for clinical assessment.

Unlike adult BMI, pediatric BMI is interpreted using percentiles that account for age and sex. The same BMI value means different things at age 5 versus age 15.
