Find your waist-to-hip ratio and the WHO cardiovascular risk category from your waist and hip circumferences.

Measure the waist at navel level and the hip at its widest point. The ratio updates instantly.

The waist-to-hip ratio (WHR) is found by dividing waist circumference by hip circumference. It shows how fat is distributed on the body:
Waist 85 cm ÷ hip 100 cm = 0.85. For men, below 0.90 means low risk; for women, below 0.80.
It is the ratio of waist circumference to hip circumference. It shows fat distribution: a high value means abdominal fat (“apple shape”), linked to higher metabolic risk.
Divide waist circumference by hip circumference. For example, waist 85 cm ÷ hip 100 cm = 0.85.
For men, below 0.90 is low risk; for women, below 0.80. Above 1.0 in men and above 0.85 in women signals raised cardiovascular risk, per the WHO.
BMI estimates total weight against height, while WHR shows where fat is stored. You can have a normal BMI but a high WHR, which remains a risk signal.
Measure the waist at navel level, relaxed, without pulling in your stomach; the hip at the widest point of the buttocks. Keep the tape horizontal and flush without squeezing.
Women naturally store more fat on hips and thighs, so their ratio is lower. Risk thresholds are adjusted for this biological difference.
Both are useful. Waist circumference alone is a simple marker of abdominal fat; WHR adds the distribution context. Many guidelines use them together.
By reducing abdominal fat: a moderate calorie deficit, regular exercise (cardio plus strength) and enough sleep. Visceral fat responds well to consistent physical activity.
