Calculate your waist-to-hip ratio
Waist-to-hip ratio (WHR) compares the circumference of your waist to that of your hips. It is a simple indicator of how body fat is distributed — a higher ratio means more fat is carried around the abdomen, which is linked to greater health risk than fat carried on the hips and thighs.
Enter your measurements in centimetres or inches (the unit cancels, so either works) and this calculator returns your ratio plus the World Health Organisation risk band for your sex. Everything runs locally in your browser, so your measurements stay private.
