Your waist-to-hip ratio (WHR) is one of the most accurate predictors of cardiovascular disease risk and metabolic health — even more reliable than BMI for many people. Our free Waist-to-Hip Ratio Calculator gives you your WHR score, health risk category, and comparison to World Health Organization (WHO) standards in seconds.
Waist-to-Hip Ratio (WHR) Calculator
What Is Waist-to-Hip Ratio (WHR)?
Waist-to-hip ratio is calculated by dividing your waist circumference by your hip circumference. It measures fat distribution — specifically whether you carry more fat around your abdomen (apple shape) or hips and thighs (pear shape).
Abdominal fat (apple shape, high WHR) is strongly linked to increased risk of type 2 diabetes, heart disease, stroke, and high blood pressure. People with fat concentrated in the hips and thighs (pear shape, low WHR) have significantly lower metabolic risk even at the same BMI.
Formula: WHR = Waist Circumference ÷ Hip Circumference
WHR Health Risk Categories (WHO Standards)
| Gender | Low Risk | Moderate Risk | High Risk |
|---|---|---|---|
| Male | Below 0.85 | 0.85 – 0.90 | Above 0.90 |
| Female | Below 0.75 | 0.75 – 0.80 | Above 0.80 |

How to Measure Correctly
- Waist: Measure at your natural waistline — the narrowest point of your torso, usually about 1 inch above your belly button. Stand up straight, exhale normally, and measure on bare skin.
- Hip: Measure at the widest point of your hips and buttocks. Stand with feet together and measure around the fullest part.
- Use a flexible tape measure and keep it parallel to the floor for accuracy.
- Take 2–3 measurements and use the average.
WHR vs BMI — Which Is Better?
| Measure | Measures | Limitation |
|---|---|---|
| BMI | Total body weight relative to height | Doesn’t distinguish fat from muscle or fat location |
| WHR | Fat distribution (where fat is stored) | Doesn’t measure total fat percentage |
| Both together | Comprehensive metabolic risk picture | Still not a replacement for clinical assessment |
Research published in The Lancet found that WHR is a better predictor of cardiovascular disease risk than BMI, particularly in people with normal BMI who carry excess abdominal fat.
Frequently Asked Questions
What is a healthy waist-to-hip ratio?
According to the World Health Organization, a healthy WHR is below 0.85 for men and below 0.75 for women (low health risk). A WHR above 0.90 for men or above 0.80 for women indicates high health risk associated with increased cardiovascular disease and metabolic syndrome.
How do you calculate waist-to-hip ratio?
Divide your waist circumference by your hip circumference using the same unit of measurement. For example, a waist of 80 cm and hips of 96 cm gives a WHR of 80 ÷ 96 = 0.83. Use the same unit (all centimeters or all inches) for both measurements.
Is waist-to-hip ratio better than BMI?
WHR and BMI measure different things. BMI measures total weight relative to height, while WHR measures where fat is distributed. WHR is generally considered a better predictor of cardiovascular disease risk because abdominal fat is specifically linked to metabolic dysfunction. Using both measures together gives a more complete health picture than either alone.
Where should I measure my waist for WHR?
Measure your waist at its natural narrowest point, typically about 1 inch (2.5 cm) above your belly button. Stand straight, exhale gently, and measure on bare skin with the tape parallel to the floor. Do not pull the tape tight — it should lie flat without compressing the skin.
Can I reduce my waist-to-hip ratio?
Yes. The most effective strategies are regular aerobic exercise (which preferentially reduces visceral abdominal fat), resistance training (which builds hip and gluteal muscle), reducing processed sugar and refined carbohydrates, and maintaining a moderate calorie deficit. WHR improvements are achievable within 8–12 weeks of consistent lifestyle changes.
