Frequently asked questions
Where do I measure?
Measure your waist at the narrowest point and your hips at the widest point, using the same unit for both — the ratio is unitless.
What do the categories mean?
WHO links higher waist-to-hip ratios to greater cardiovascular risk, with different thresholds for men and women. This is general guidance, not a diagnosis.
