A useful starting point
One number.
A bigger picture.

What it means
A screening measure, not a verdict.
BMI uses height and weight. It does not directly measure body fat, diagnose a condition, or decide which treatment is appropriate. This adult calculator is not designed for children or teens. Discuss pregnancy or other circumstances requiring specialized interpretation with a clinician.
