Waist-to-Hip Ratio Calculator
Waist-to-hip ratio (WHR) divides your waist measurement by your hip measurement to describe body-fat distribution, a health indicator the World Health Organization treats as complementary to BMI. Enter waist and hip measurements in the same unit (centimeters or inches) and your sex, and this tool returns the ratio along with a low, moderate, or high risk band based on WHO thresholds. This is a screening estimate, not a diagnosis.

How it works
- Choose your sex.
- Enter your waist and hip measurements using the same unit for both.
- Read your WHR and its WHO-based risk band.
Formula WHR = waist / hip
Frequently asked questions
How do I measure my waist and hips for this calculator?
Measure your waist at the narrowest point, usually just above the navel, and your hips at the widest point around the buttocks, using the same tape and unit for both.
What is a healthy waist-to-hip ratio?
The WHO generally treats below 0.90 as lower risk for men and below 0.80 as lower risk for women, with risk rising as the ratio increases.
Why does WHR differ from BMI?
BMI only relates height and weight; it says nothing about where fat is stored. WHR specifically flags abdominal fat, which many studies associate with higher metabolic risk.
Can I use inches instead of centimeters?
Yes. WHR is a ratio, so any unit works as long as you use the same unit for both waist and hip measurements.
Is a high WHR a diagnosis?
No. This is an educational screening estimate, not a medical diagnosis. Discuss body composition and health risk with a healthcare provider.
