Waist-to-Hip Ratio Calculator
Calculate your WHR and assess your health risk. Waist-to-hip ratio predicts heart disease and diabetes more reliably than BMI alone.
Measure at navel height or the narrowest point
Measure at the widest point across the buttocks

📏 How to measure correctly
Waist:
Stand upright and measure at navel height or the narrowest point of the waist. Breathe out gently before measuring.
Hips:
Measure at the widest point across the buttocks. Keep the tape horizontal and snug — not compressing the skin.
Why does waist-to-hip ratio matter?
BMI tells you a lot about your weight relative to height, but nothing about where that fat is located. WHR fills that gap. Visceral fat — the fat that accumulates around the internal organs — is metabolically active and releases inflammatory compounds that raise the risk of heart disease, type 2 diabetes, and hypertension.
Research consistently shows that WHR predicts heart attack risk better than BMI. A person can have a normal BMI yet carry a metabolically unhealthy fat distribution — a phenomenon known as TOFI (Thin Outside, Fat Inside).
WHR reference values (WHO)
| Risk category | Women | Men |
|---|---|---|
| ✅ Low risk | < 0.75 | < 0.85 |
| 🟡 Moderate risk | 0.75–0.80 | 0.85–0.90 |
| ⚠️ Elevated risk | 0.80–0.85 | 0.90–1.00 |
| 🚨 High risk | > 0.85 | > 1.00 |
How to reduce belly fat
Cardio exercise
Running, cycling, and swimming are the most effective tools for burning visceral fat. Aim for 150–300 minutes per week.
HIIT training
High-intensity interval training burns visceral fat more effectively than steady-state cardio at the same total duration.
Strength training
Muscle mass raises basal metabolic rate, helping keep body fat percentage in check even at rest.
Calorie deficit
Visceral fat only decreases through an overall calorie deficit. Spot fat reduction is not physiologically possible.
Sleep
Sleeping fewer than 6 hours is linked to greater visceral fat accumulation through elevated cortisol.
Stress management
Cortisol specifically drives abdominal fat storage. Mindfulness, recovery, and social connection all help reduce chronic stress.
