How it works
Measure your waist and your hips with the tape level and snug. Divide the waist number by the hip number.
Both measurements must use the same unit, since the ratio itself has no unit.
Worked example
A waist of 34 in and hips of 40 in give a ratio of 0.85.
Questions
Is a high ratio a problem?
This page does not rate the ratio. Ask a doctor what your measurements mean for your health.
Where should I measure?
Guidance varies, but the waist is often measured at its narrowest point and the hips at their widest. Keep the tape level.
Is this the same as BMI?
No. BMI uses height and weight. This ratio uses two body measurements, around the waist and the hips.
