About this tool
Where your body stores fat matters as much as how much you carry, and the waist-to-hip ratio is a simple way to gauge it. Enter your waist and hip measurements and this calculator returns the ratio and the World Health Organization’s risk category for your sex.
It takes just a tape measure and a moment, making it an easy companion to BMI and body-fat estimates. Remember it’s a general screening guide, not medical advice — a professional can interpret it in context. Everything runs in your browser.
Frequently asked questions
How do I measure correctly?
Measure the waist at its narrowest point and the hips at their widest, keeping the tape level and snug but not tight.
What do the categories mean?
The World Health Organization links higher ratios to greater health risk, with different thresholds for men and women. It's a screening guide, not a diagnosis.
