Understanding Waist-to-Hip Ratio
WHR = Waist Circumference ÷ Hip Circumference. It indicates whether fat is stored around the abdomen (apple shape) or hips (pear shape).
WHO Risk Categories
| Risk | Men | Women |
|---|---|---|
| Low | <0.90 | <0.80 |
| Moderate | 0.90-0.99 | 0.80-0.84 |
| High | ≥1.00 | ≥0.85 |
Apple-shaped bodies have higher risk for heart disease, diabetes, and stroke.
How to Use This Waist-to-Hip Ratio Calculator
Enter your waist circumference (measured at the belly button) and hip circumference (measured at the widest part of buttocks). Select your gender for appropriate health thresholds.
Formula & How It Works
Ratio = Waist / Hip. WHO classifications β Low risk: Men β€ 0.90, Women β€ 0.80. Moderate: Men 0.91-0.99, Women 0.81-0.85. High: Men β₯ 1.0, Women β₯ 0.86.
Calculation Example
Male, waist 36", hips 38": Ratio = 0.95. WHO classification: moderate risk. Target: reduce waist to 34" for ratio 0.89 (low risk).
Expert Tips
Measure at the same time of day (morning, fasting) for consistency. Stand relaxed β don't suck in your stomach. Combine with BMI and body fat percentage for a comprehensive health assessment.
Frequently Asked Questions
What is a healthy WHR?
Men: below 0.90. Women: below 0.80. Higher ratios indicate visceral fat and increased disease risk.
WHR vs BMI?
WHR measures fat distribution (where fat is stored). BMI measures overall weight. WHR is a better predictor of heart disease.
How to measure waist?
Measure at the narrowest point between ribs and hip bones (usually at the navel). Measure hips at the widest point.
