What is a healthy waist-to-hip ratio?

For men: WHR below 0.90 is low risk, 0.90-0.99 is moderate risk, above 1.0 is high risk. For women: WHR below 0.80 is low risk, 0.80-0.85 is moderate risk, above 0.85 is high risk.

How do I measure waist and hip circumference correctly?

Waist: Measure at the narrowest point between ribs and hips, usually at navel level. Hip: Measure at the widest part of the buttocks. Stand relaxed, exhale normally, and keep tape parallel to floor.

Is WHR better than BMI for health assessment?

WHR and BMI measure different things. WHR specifically indicates central obesity and fat distribution, which is strongly linked to cardiovascular risk. BMI measures overall body mass. Both provide valuable health information.

Waist-to-Hip Ratio Calculator

Calculate your WHR to assess fat distribution and health risks. A simple ratio that indicates cardiovascular disease and diabetes risk.

Body Measurements

Waist Circumference

Measure at narrowest point, just above belly button

Hip Circumference

Measure at widest part of hips and buttocks

Gender

WHR Result

Enter measurements to assess health risks

Health Assessment

WHR indicates fat distribution patterns. Central obesity (apple shape) carries higher health risks than peripheral fat (pear shape).

Risk Thresholds

Men: High risk ≥0.90. Women: High risk ≥0.85. These thresholds indicate increased cardiovascular and diabetes risks.

Measurement Tips

Measure waist at narrowest point after exhaling. Measure hips at widest point. Use same units for both measurements.

WHR Formula

WHR = Waist Circumference ÷ Hip Circumference

WHO Health Risk Categories

Men: Low <0.85, Moderate 0.85-0.90, High ≥0.90
Women: Low <0.80, Moderate 0.80-0.85, High ≥0.85
