CDC BMI calculator

This BMI calculator uses the official formulas for Body Mass Index (BMI) provided by The Centers for Disease Control and Prevention (CDC). It's the USA's leading national health institute.

The calculator is suitable for all ages. Remember that BMI is not a professional diagnostic tool. Any results you get from this app should not be taken as medical advice, but only as an indicator if you or your child need further assessment.

The American Academy of Pediatrics recommends calculating BMI regularly to screen for potential weight and health issues.
