Quick answer: Waist-to-Hip Ratio = Waist Measurement ÷ Hip Measurement. Use our free Waist to Hip Ratio Calculator to check your ratio against WHO guidelines.
Why This Ratio Matters
Where body fat is stored matters for health risk, not just how much there is. A higher waist-to-hip ratio (more fat around the abdomen) is associated with greater cardiovascular risk than fat stored around the hips, even at the same overall body weight.
WHO Risk Categories
The World Health Organization generally considers a ratio above 0.90 (men) or 0.85 (women) to indicate increased health risk, though this is one indicator among many, not a standalone diagnosis.
Frequently Asked Questions
How do I measure my waist and hips correctly?
Measure your waist at the narrowest point (usually just above the belly button) and your hips at the widest point, both without pulling the tape tight.
Is this more useful than BMI?
Waist-to-hip ratio captures fat distribution, which BMI doesn't — many practitioners consider it a useful complement to BMI, not a replacement.
Should I be concerned about a high ratio?
A high ratio is a risk indicator worth discussing with a healthcare provider, not a diagnosis on its own.
