Waist-to-Hip Ratio Calculator
Calculate waist-to-hip ratio from simple tape measurements and compare the result with common sex-specific screening cutoffs.
This tool is built for quick screening and trend tracking. It helps you see how waist size compares with hip size, but it does not replace clinical advice or diagnosis.

Medical disclaimer
- Waist-to-hip ratio is a screening tool and does not diagnose disease.
- Pregnancy, body-shape changes, and some medical conditions can affect interpretation.
- Use the ratio with blood pressure, labs, symptoms, and wider clinical context.
Waist-to-hip ratio is a simple screening ratio. Use it with broader health context rather than as a diagnosis.
Medical disclaimer
This calculator provides educational guidance only. It does not replace professional medical advice, diagnosis, or treatment.
- Waist-to-hip ratio is only one screening measure of body-fat distribution.
- Cutoffs are general adult screening thresholds and do not capture every individual factor.
- Seek professional advice if you have symptoms or multiple cardiometabolic risk factors.
How to use this calculator
Measure waist correctly
Use the same waist landmark each time so trend tracking stays meaningful. Keep the tape level and avoid tightening it into the skin.
Measure hips consistently
Measure at the widest point around the hips and glutes. Small tape-position changes can shift the ratio.
Keep units matched
The ratio is unitless, so centimeters and inches both work. The only rule is that both measurements must use the same unit.
Use sex cutoffs
Common lower-risk and higher-risk cutoffs differ for men and women, which is why the calculator asks for sex first.
Track trends over time
The best use of this tool is usually trend tracking. Recheck with the same technique rather than reacting to one reading.
Know the limitations
Waist-to-hip ratio is a screening measure, not a diagnosis. Use it alongside other health markers and clinical context.
