Waist-to-Hip Ratio Calculator
Divide your waist measurement by your hip measurement to assess body-fat distribution and related health risk. Use the same unit for both.

–What is the waist-to-hip ratio?
The waist-to-hip ratio (WHR) compares the circumference of your waist to that of your hips. It is a quick way to assess where your body stores fat. Fat carried around the abdomen ("apple" shape) carries more health risk than fat stored around the hips and thighs ("pear" shape), and WHR captures this difference in a way that BMI cannot.
How to measure correctly
Measure your waist at the narrowest point, usually just above the belly button, keeping the tape snug but not tight. Measure your hips at the widest part of your buttocks. Stay relaxed and breathe normally. Then divide the waist measurement by the hip measurement — the calculator does this for you. Use the same unit (centimetres or inches) for both.
What the result means
| Risk level | Men | Women |
|---|---|---|
| Low | 0.90 or below | 0.80 or below |
| Moderate | 0.91–0.99 | 0.81–0.84 |
| High | 1.0 or above | 0.85 or above |
These thresholds are based on World Health Organization guidance. A higher ratio is associated with an increased risk of cardiovascular disease and type 2 diabetes. WHR is best used alongside other measures rather than on its own.
Frequently asked questions
Is waist-to-hip ratio better than BMI?
It is not better, just different. WHR shows fat distribution, while BMI shows overall weight relative to height. Using both gives a fuller picture of your health.
How can I improve my ratio?
Reducing abdominal fat through a modest calorie deficit, regular activity, good sleep, and lower stress all help. Spot reduction is a myth, so focus on overall fat loss.
