How This Is Calculated
Waist-to-hip ratio (WHR) compares the circumference of your waist to your hips. It’s used as a simple indicator of where body fat is stored, which matters more for health risk than total weight alone.
The Formula
WHR = waist circumference ÷ hip circumference, measured in the same unit.
Risk Categories
Men: below 0.90 is low risk, 0.90–0.99 is moderate, 1.0 and above is high risk. Women: below 0.80 is low risk, 0.80–0.85 is moderate, 0.85 and above is high risk. Carrying more weight around the waist is generally associated with higher health risk.
A screening ratio, not a diagnosis.
Measure at the narrowest part of your waist and the widest part of your hips for consistency. Combine with waist-to-height ratio for a fuller picture.

Frequently asked questions
What does waist-to-hip ratio tell me?
It reflects how your body fat is distributed. Higher ratios indicate more fat carried around the abdomen, which is associated with greater health risk than fat carried on the hips and thighs.
What ratio is considered healthy?
The World Health Organization generally considers a ratio above 0.90 for men and 0.85 for women to indicate increased health risk, though this varies by population.
How should I measure my waist and hips?
Measure your waist at the narrowest point (usually just above the navel) and your hips at the widest point, keeping the tape snug but not compressing the skin.
Is this ratio more useful than BMI?
Many researchers consider waist-to-hip ratio a better indicator of health risk than BMI alone, since it reflects fat distribution rather than just overall size.
