Waist-to-Hip Ratio Calculator
Divide waist by hip circumference to gauge health risk.
Where you carry weight matters
The waist-to-hip ratio captures how fat is distributed, which research links to health risk more closely than weight alone. Carrying more around the waist than the hips raises that risk.
Divide waist by hip circumference in the same units. The World Health Organization considers ratios above 0.90 for men and 0.85 for women a sign of increased risk. A value of 0.85 on an 85/100 measurement sits at the female threshold.

Frequently Asked Questions
What does the ratio show?
How fat is distributed. A higher waist-to-hip ratio means more around the midsection, which is linked to greater metabolic and cardiovascular risk.
What are the thresholds?
The World Health Organization flags increased risk above 0.90 for men and 0.85 for women. Lower ratios sit in the healthier range.
How do I measure?
Measure the narrowest part of your waist and the widest part of your hips, using the same units for both.
