Waist-to-Hip Ratio Calculator
A quick check of fat distribution and related health risk, per WHO guidance.
Health Risk by Ratio (WHO)
Men
| Low risk | < 0.90 |
| Moderate risk | 0.90 – 0.99 |
| High risk | ≥ 1.0 |
Women
| Low risk | < 0.80 |
| Moderate risk | 0.80 – 0.84 |
| High risk | ≥ 0.85 |
A higher waist-to-hip ratio indicates more abdominal fat, which is linked to greater cardiovascular risk than fat stored elsewhere. This is a screening tool, not a diagnosis.
What Waist-to-Hip Ratio Measures
Waist-to-hip ratio (WHR) compares the circumference of your waist to your hips, giving insight into where your body stores fat. Fat stored around the abdomen ("apple" shape) is associated with higher cardiovascular risk than fat stored around the hips and thighs ("pear" shape), even at the same body weight.
How to Measure Correctly
- Waist: measure at the narrowest point, usually just above the belly button
- Hip: measure at the widest point around the buttocks
- Use a flexible tape measure, standing relaxed, without pulling it tight
Why This Complements BMI
BMI doesn't show where fat is distributed on the body, while WHR specifically flags abdominal fat, a known independent risk factor. Using WHR alongside our BMI Calculator and Body Fat Calculator gives a fuller picture than any single measurement alone.
Frequently Asked Questions
What's a healthy waist-to-hip ratio?
According to WHO guidance, low risk is generally below 0.90 for men and below 0.80 for women — see the full risk table on this page.
Is waist-to-hip ratio more useful than BMI?
They measure different things — BMI reflects overall weight relative to height, while WHR reflects fat distribution. Many health professionals consider using both together more informative than either alone.
Can I reduce my waist-to-hip ratio?
Waist circumference specifically tends to respond to overall fat loss through diet and exercise. This is general information, not personalised medical advice — consult a healthcare provider for guidance.
