Calculate your waist-to-hip ratio and see WHO health risk classification.
Waist-to-hip ratio (WHR) is a simple measurement of body fat distribution calculated by dividing waist circumference by hip circumference, used by the WHO as a key indicator of cardiovascular and metabolic disease risk.
| Risk | Male | Female |
|---|---|---|
| Low Risk | < 0.90 | < 0.80 |
| Moderate Risk | 0.90 to 0.95 | 0.80 to 0.85 |
| High Risk | > 0.95 | > 0.85 |
Formula
WHR = Waist Circumference ÷ Hip CircumferenceWaist = Circumference at the narrowest point (cm)
Hip = Circumference at the widest point (cm)
WHR = Ratio indicating fat distribution pattern
Worked Example
Male with 85 cm waist, 100 cm hips
Did you know? A 2007 Lancet study of 27,000 people across 52 countries found that waist-to-hip ratio was a stronger predictor of heart attack risk than BMI, accounting for one-third of the population attributable risk (source: The Lancet).
