Waist-to-Hip Ratio Calculator
Calculate your waist-to-hip ratio (WHR) and assess your health risk category based on WHO guidelines. A key indicator of central obesity and metabolic risk.

How to use this calculator
A WHR above 0.90 in men or 0.85 in women indicates central obesity with increased cardiovascular and metabolic risk.
- 1
Measure your waist at the narrowest point (usually just above the belly button).
- 2
Measure your hips at the widest point around the buttocks.
- 3
Use the same unit (cm or inches) for both measurements.
- 4
Select your sex — WHO thresholds differ between males and females.
Frequently asked questions
Why does body shape matter for health?
Fat stored around the abdomen (apple shape, high WHR) is more metabolically active and is associated with higher risk of type 2 diabetes, heart disease, and stroke compared to fat stored around the hips and thighs (pear shape).
What is the ideal waist-to-hip ratio?
WHO recommends WHR below 0.90 for men and 0.85 for women. Values at or above these thresholds indicate central obesity. Lower WHR (e.g., 0.70–0.75 for women) is associated with lower cardiometabolic risk.
Is WHR better than BMI?
WHR is considered a better predictor of cardiovascular risk than BMI because it specifically captures central (visceral) fat distribution, which is more dangerous than overall body fat. Both measurements are useful in combination.

Central obesity and health risk
Central obesity — excess fat stored in the abdominal area — is a key risk factor for metabolic syndrome, type 2 diabetes, and cardiovascular disease. Unlike subcutaneous fat (under the skin), visceral fat (around the organs) releases inflammatory chemicals that impair insulin sensitivity and raise blood pressure.
Measuring accurately
For waist: stand relaxed, exhale normally, and measure halfway between the bottom rib and the top of the hip bone (iliac crest) — usually around the navel. For hips: measure around the widest part of the buttocks. Do not hold your breath or pull your stomach in. Repeat twice and use the average.
