WHR = waist ÷ hip

Formula
How this is calculated
The waist-to-hip ratio is a single division: your waist circumference divided by your hip circumference. Both must be measured in the same unit (this tool uses centimetres), so the units cancel and the result is a pure dimensionless ratio. Measure the waist at its narrowest point and the hips at their widest, keeping the tape level and snug. A larger number means more of your girth is at the waist relative to the hips, which signals more central (abdominal) fat.
The ratio is then compared against sex-specific risk thresholds from the World Health Organization, because men and women carry fat differently. For men the bands are low (≤ 0.85), moderate (0.85–0.90), and high (> 0.90); for women they are low (≤ 0.80), moderate (0.80–0.85), and high (> 0.85).
WHR is a screening proxy, not a diagnosis: it does not account for height, total body fat, muscle, posture, or measurement error, and it can mislead during pregnancy. It complements BMI by describing where fat sits rather than how much there is.
Examples
| Input | Result |
|---|---|
| Male, waist 85 cm, hip 100 cm | WHR 0.85 — low to moderate risk |
About this calculator
The waist-to-hip ratio (WHR) compares the circumference of your waist to that of your hips, giving a quick indicator of how fat is distributed around your body. A higher ratio reflects more abdominal (central) fat, which research links to a greater risk of heart disease, type 2 diabetes, and other metabolic conditions than fat carried around the hips and thighs.
The World Health Organization considers a ratio above 0.90 for men and 0.85 for women to indicate substantially increased health risk. Measure your waist at its narrowest point and your hips at their widest, keeping the tape level and snug but not compressing the skin. WHR complements BMI because it captures where fat sits, not just how much there is.
Frequently asked questions
A ratio at or below 0.90 for men and 0.85 for women is generally considered lower risk by the World Health Organization.
Abdominal fat is metabolically active and more strongly tied to cardiovascular and metabolic risk than fat stored on the hips and thighs.
Measure the waist at its narrowest point and the hips at their widest, with the tape level and snug against the skin without compressing it.
