About the BMI Calculator

Enter your height and weight to get your body mass index, the World Health Organization category it falls into, and the weight range that corresponds to a BMI of 18.5-24.9 at your height.

BMI is a population-level screening measure. It does not distinguish muscle from fat and is not a diagnosis - discuss results with a healthcare professional.
