Waist-to-hip ratio calculator

Waist-to-hip ratio 0.85 Low risk

Relates waist and hip circumference as an indicator of fat distribution. The WHO links higher cardiovascular risk above 0.90 in men and 0.85 in women. Not a medical diagnosis.

This waist-to-hip ratio calculator works out your ratio and its risk level using WHO thresholds, based on your sex, waist and hip measurements.

Beyond BMI

The waist-to-hip ratio complements BMI: abdominal fat is linked to more cardiovascular risk than fat around the hips. Measure it with a tape measure. For guidance only — it does not replace advice from a healthcare professional.

FAQ

What is the waist-to-hip ratio?
It's the ratio between your waist and hip circumference. It indicates how body fat is distributed, which is a cardiovascular risk factor.
What values are considered risky?
The WHO links higher risk to a ratio above 0.90 in men and 0.85 in women. It's a complementary indicator to BMI, not a diagnosis.
How do I measure my waist and hips correctly?
Measure your waist at the narrowest point (usually just above the belly button) and your hips at the widest point, both with the tape snug but not tight.
