Waist-to-Hip Ratio Calculator
Waist-to-hip ratio (WHR) divides your waist circumference by your hip circumference. It is one of the strongest proxies for visceral abdominal fat, which is more closely linked to cardiovascular risk than total weight or BMI alone. The WHO sets sex-specific thresholds: men >0.90 and women >0.85 indicate elevated risk.
When to use this calculator
- Monthly tracking of body fat distribution while following a diet or exercise programme.
- Understanding whether your current weight is distributed favourably (gluteo-femoral) or at risk (abdominal).
- Complementing BMI with an indicator that distinguishes visceral from peripheral fat.
- Documenting progress for discussions with a doctor or nutritionist over time.
Example: man with 92 cm waist and 100 cm hips
- Waist circumference: 92 cm
- Hip circumference: 100 cm
- WHR = 92 ÷ 100 = 0.92
- For men: 0.90–0.95 = moderate risk (WHO)
How it works
1 min readWaist-to-hip ratio compares where fat accumulates in your body. Abdominal (visceral) fat is metabolically more active and more harmful than peripheral (gluteo-femoral) fat.
How it's calculated
WHR = Waist circumference (cm) ÷ Hip circumference (cm)Example: waist 88 cm ÷ hips 100 cm = WHR 0.88
WHO Risk Classification
| Risk level | Men | Women |
|---|---|---|
| Low | < 0.90 | < 0.80 |
| Moderate | 0.90 – 0.95 | 0.80 – 0.85 |
| High | > 0.95 | > 0.85 |

How to measure correctly
Waist: Measure at the narrowest point of your torso, roughly midway between the bottom of your last rib and the top of your hip bone. Breathe normally and measure at the end of a natural exhale without sucking in.
Hips: Measure at the widest point of your hips and buttocks, with the tape parallel to the floor. Keep the tape snug but not tight.
Why sex matters
Women have naturally wider pelvic structure and a hormonally different fat distribution pattern, leading to proportionally larger hips and lower WHR values. That is why WHO thresholds differ by sex.

Frequently asked questions
What is waist-to-hip ratio and what does it measure?
Waist-to-hip ratio (WHR) divides your waist circumference by your hip circumference. A higher value indicates more fat concentrated in the abdomen (visceral fat) relative to hips and buttocks. Visceral fat is metabolically active and strongly associated with cardiovascular disease, insulin resistance, and metabolic syndrome.
How do I measure my waist correctly?
Measure at the narrowest point of your torso, midway between the bottom of your last rib and the top of your hip bone (iliac crest). Use a flexible tape measure, keep it horizontal, and measure at the end of a normal exhale without tensing your abdomen or pulling the tape too tight.
How do I measure my hips correctly?
Measure at the widest point of your hips and buttocks, with the tape parallel to the floor and snug but not compressing. Thin clothing is fine. Having someone assist you improves accuracy, especially at the back.
What are healthy WHR values for men and women?
Per WHO guidelines: for men, below 0.90 is low risk, 0.90–0.95 is moderate risk, and above 0.95 is high risk. For women, below 0.80 is low risk, 0.80–0.85 is moderate risk, and above 0.85 is high risk. Women's thresholds are lower due to naturally wider hip structure.
Is WHR better than BMI for assessing cardiovascular risk?
Often yes. WHR measures fat distribution rather than total weight, and studies show it predicts cardiovascular events more strongly than BMI alone. A person can have a normal BMI but a high WHR (fat concentrated in the abdomen), which already carries metabolic risk. Using both together gives the most complete picture.
What diseases are linked to a high waist-to-hip ratio?
A high WHR is an independent risk factor for coronary artery disease, stroke, hypertension, type 2 diabetes, metabolic syndrome, and certain cancers (colorectal, endometrial). The WHO classifies it as a clinical indicator of central obesity.
How can I lower my waist-to-hip ratio?
WHR improves mainly by reducing waist circumference (you cannot easily reduce hip bone structure). What works best: regular aerobic exercise (brisk walking, swimming, cycling), strength training, a diet low in added sugars and ultra-processed foods, reduced alcohol intake, and managing chronic stress.
How often should I check my WHR?
For general health monitoring, every one to three months is sufficient. If you are actively making lifestyle changes (diet + exercise), monthly measurements help track progress. Daily measurements are not useful since hydration fluctuations cause day-to-day variation.
Is this calculator reliable for athletes and muscular people?
WHR is less reliable for athletes with significant gluteal and thigh muscle mass, since larger hips (from muscle, not fat) lower the ratio and can underestimate risk. Athletes should combine WHR with body fat percentage assessment via skinfold calipers or bioelectrical impedance for better accuracy.
