If you’re looking for a child BMI percentile chart, calculator, or help interpreting BMI percentile by age and gender, this page can help you make sense of the numbers and what they may mean for your child’s growth.

A child’s BMI percentile is not the same as an adult BMI number. For children and teens, BMI is interpreted by age and gender and then compared with growth chart data for other children of the same age and sex.
