Waist-to-Hip Ratio Calculator: The Complete Guide
Calculate your waist-to-hip ratio (WHR). Enter your waist and hip measurements to get your ratio and the health-risk band the World Health Organization associates with it for your sex.
Who the Waist-to-Hip Ratio Calculator is for
People assessing fat distribution and related health risk beyond what BMI shows.

How it works
Waist-to-hip ratio = waist circumference ÷ hip circumference. Because both use the same unit, the ratio is unit-free. The WHO flags raised risk above 0.90 for men and 0.85 for women.

Why fat distribution matters
Where you carry fat matters as much as how much you carry. A higher waist-to-hip ratio signals more abdominal ('apple-shaped') fat, which is linked to greater cardiovascular and metabolic risk than fat carried on the hips and thighs. WHR is a quick, equipment-free complement to BMI for assessing that risk.
