Formula
Waist-to-hip ratio = waist circumference ÷ hip circumference
Example: waist 84 cm and hip 98 cm gives 84 ÷ 98 = 0.86.
WHR and waist size cut-offs
| Men | Women | |
|---|---|---|
| Waist-to-hip ratio linked to higher risk (WHO) | 0.90 or more | 0.85 or more |
| Waist size linked to higher risk (Asian cut-off) | 90 cm (35.4 in) or more | 80 cm (31.5 in) or more |
How to measure
Stand straight and breathe out gently. Measure your waist midway between the bottom of your ribs and the top of your hip bone, and your hips around the widest part of your buttocks. Keep the tape level.
