What to know

Child and Teen BMI Calculator in relation to your height is referred to as your body mass index (BMI). For youths, BMI is interpreted through sex-specific BMI-for-age percentiles. This calculator provides BMI and the corresponding BMI-for-age percentile on a CDC BMI-for-age growth chart for children and teens 2-19 years.

This calculator provides BMI and the corresponding BMI weight status category for children and adolescents 2 to 19 years of age. The calculator also generates a BMI percentile and creates a growth chart based on the user’s information, along with an explanation of the results. Due to possible rounding errors in age, weight, and height, the results from this calculator may differ slightly from other programs.

BMI is just one possible measure of health; it should be considered along with other signs when evaluating someone's health status. Such variables may include a patient's medical history, health practices, physical examination findings, and laboratory data. Individuals should consult a healthcare provider about their BMI.
