Waist-to-Hip Ratio Calculator
The waist-to-hip ratio (WHR) compares the size of your waist to your hips to assess how your body stores fat. Enter your measurements to see your ratio and World Health Organization risk band.
Used because the formula differs for men and women.
Measure at the narrowest point, after breathing out.
Measure at the widest point.
- Low risk
- Increased risk
- High risk
WHO links higher abdominal fat with greater health risk above 0.90 for men.

How waist-to-hip ratio works
WHR is your waist circumference divided by your hip circumference, using the same unit for both. A higher ratio means more fat is carried around the middle (an "apple" shape) rather than the hips and thighs (a "pear" shape). Central fat is the pattern most strongly linked to health risk.
Measure your waist at its narrowest point and your hips at their widest, keeping the tape horizontal and snug. Stand relaxed and breathe out normally before reading each measurement.
WHO risk thresholds
The World Health Organization considers abdominal obesity — and substantially increased health risk — to begin above these ratios:
- Men: a ratio above 0.90 indicates increased risk.
- Women: a ratio above 0.85 indicates increased risk.
- Lower ratios (at or below those thresholds) are associated with lower risk.
What your ratio tells you
A high WHR is associated with greater risk of type 2 diabetes, high blood pressure, heart disease and stroke, independent of overall weight. Some large studies have found WHR predicts heart-attack risk more strongly than BMI, because it captures dangerous abdominal fat directly.
WHR does have limits: it can be skewed by a naturally wide or narrow pelvis, and it is less reliable at very high BMIs. For a rounded view of central-fat risk, consider it alongside waist-to-height ratio and your BMI, and speak to a clinician if your ratio is above the WHO threshold.
