What BMI can and cannot tell you

BMI is a screening metric based on height and weight. It can help compare weight ranges, but it does not directly measure muscle mass, body composition, pregnancy status, or individual medical risk.

Reference ranges

The calculator supports WHO and Asian adult BMI reference ranges. Choose the range that best fits the context you are using, and treat the result as an estimate rather than a diagnosis.
