Find your waist-to-hip ratio in seconds. This free WHR calculator divides your waist by your hip measurement and shows the WHO health band — a general indicator of where you carry weight, not a diagnosis.

Measure your waist at the narrowest point and hips at the widest. Units cancel out, so cm or inches give the same ratio.

WHR is one general indicator of where you carry weight — not a diagnosis. Discuss your health with a healthcare professional.
Use this free waist-to-hip ratio calculator to find your WHR and see which health band it falls in. Enter your waist and hip measurements in centimetres or inches to get your ratio instantly.
What this waist-to-hip ratio calculator shows you
A waist-to-hip ratio (WHR) calculator divides your waist measurement by your hip measurement. The result shows where you tend to carry weight and which World Health Organization risk band it falls in — low, moderate or high — using sex-specific thresholds.
How waist-to-hip ratio is calculated
WHR = Waist measurement ÷ Hip measurement
Because both numbers use the same units, they cancel out — so centimetres and inches give the same ratio. A waist of 85 and hips of 100 give a WHR of 0.85.
WHO waist-to-hip ratio bands
Health indication
Men
Women
Low
below 0.90
below 0.80
Moderate
0.90 – 0.99
0.80 – 0.84
High
1.0 and above
0.85 and above
These thresholds differ by sex because of natural differences in body shape.
How to measure for an accurate WHR
Waist: measure at the narrowest point, usually just above the belly button, without holding your breath.
Hips: measure around the widest part of your buttocks.
Keep the tape level and snug but not compressing the skin.
Enter both in the same units — cm or inches.
Apple vs pear shape
A higher ratio means more weight around the middle (an “apple” shape); a lower ratio means more around the hips (a “pear” shape). Researchers study WHR because where weight sits can matter for health, but it’s just one general indicator among many.

Waist-to-Hip Ratio FAQ
How do I calculate my waist-to-hip ratio?
Divide your waist measurement by your hip measurement. A waist of 85 and hips of 100 give a ratio of 0.85.
Both measurements must use the same units, but cm or inches give the same result.
What is a healthy waist-to-hip ratio?
The WHO considers below 0.90 low risk for men and below 0.80 for women.
Moderate is 0.90–0.99 for men and 0.80–0.84 for women; higher than that falls in the high risk range.
Why are the bands different for men and women?
Men and women naturally differ in body shape and fat distribution, so the WHO uses separate thresholds
to make the indicator meaningful for each.
How should I measure my waist and hips?
Measure your waist at its narrowest point (usually just above the navel) and your hips at the widest part of your buttocks,
keeping the tape level and snug without compressing the skin.
Is WHR better than BMI?
They measure different things. BMI relates weight to height, while WHR shows where weight is carried.
Many people look at both, but neither is a diagnosis — they're general indicators best interpreted with a professional.
