About BMI

Limitations
BMI doesn't account for muscle mass, bone density, or fat distribution. Athletes may score 'overweight' despite low body fat.
Healthy range
A BMI between 18.5 and 24.9 is considered healthy for most adults. Individual variation applies.
Children
BMI for children and teens uses different age- and sex-specific scales. This calculator is for adults (18+).
