Calculate BMI

What BMI measures

BMI, or body mass index, compares weight with height. The traditional formula is weight in kilograms divided by height in meters squared.

Results shown

The calculator shows traditional BMI, an adult weight category, a comparison value called new BMI and an estimated healthy weight range for the entered height.

Example

A person who is 1.80 m tall and weighs 80 kg has a traditional BMI of about 24.7. The exact interpretation still depends on the person and the limits of BMI as a simple screening measure.

Adults only

The adult BMI categories shown by the calculator are not designed for children or teenagers. Growth, age and sex-specific reference curves are needed for younger people.

Important limitations

BMI does not measure body composition, muscle mass or fat distribution. The result is an estimate for adults and is not medical advice or a diagnosis.
