Calculate your Waist-to-Hip Ratio (WHR) to assess health risks and determine your body shape. WHR is an important indicator of cardiovascular health and fat distribution.
Example: Waist: 80 cm, Hip: 100 cm → WHR: 0.80 (Low risk for women, Moderate risk for men)
Waist-to-hip ratio (WHR) compares the circumference of your waist to that of your hips. It's a simple indicator of how fat is distributed on your body, and research links a higher ratio (more belly fat) to greater cardiovascular and metabolic risk.
How it's calculated
WHR = waist measurement ÷ hip measurement. The units cancel out, so you can use centimetres or inches as long as both use the same unit.

How to measure correctly
Measure your waist at the narrowest point, usually just above the belly button.
Measure your hips at the widest point of your buttocks.
Keep the tape level and snug but not compressing the skin.
Enter both values and your sex, then calculate.
WHR is a screening tool, not a diagnosis — discuss any concerns with a healthcare professional.
Frequently Asked Questions
Is WHR better than BMI?
WHR captures where fat is stored, which BMI ignores. Many clinicians use both together for a fuller picture of health risk.
What is a healthy waist-to-hip ratio?
Generally below 0.90 for men and below 0.80 for women is considered low risk, though guidance varies.
Should I measure in cm or inches?
Either works. Because WHR is a ratio, the units cancel out as long as you use the same unit for waist and hip.
