BMI Percentile Calculator for Child and Teen

This calculator is not meant to serve as a source of clinical guidance and is not intended to be a substitute for professional medical advice.
Because of possible rounding errors in age, weight, and height, the results from this calculator may differ slightly from BMI-for-age percentiles calculated by other programs. To calculate the correct BMI and BMI-for-age percentile, it is important to measure height and weight accurately.
For people 20 years old and older, use the Adult BMI Calculator.
