Waist-to-Hip Ratio Calculator

Estimate your fat-distribution risk band.

How it’s calculated

This divides your waist measurement by your hip measurement and reads it against WHO risk thresholds.

WHR = waist ÷ hip. Higher risk above 0.90 (men) or 0.85 (women); the calculator also flags a moderate band.
