Waist-to-Hip Ratio Calculator: Assess Your Body Shape and Health Risk
Where you carry your body fat matters as much as how much you carry. The waist-to-hip ratio (WHR) is a simple but powerful measure of fat distribution that predicts cardiovascular and metabolic health risk — often better than BMI alone. Our WHR Calculator computes your ratio and interprets it against WHO standards and Indian-population-specific risk thresholds.
What Is Waist-to-Hip Ratio?
WHR = Waist Circumference ÷ Hip Circumference. Both measured in the same unit (cm or inches). Waist measured at the narrowest point between the bottom rib and the iliac crest (top of the hip bone) — typically at or just above the navel. Hip measured at the widest point around the buttocks.
Example: Waist = 80 cm, Hip = 95 cm. WHR = 80 ÷ 95 = 0.84.
WHR Risk Thresholds (WHO Standards)
Men: Low risk: WHR ≤ 0.90 | Moderate risk: 0.91–0.99 | High risk: ≥ 1.00
Women: Low risk: WHR ≤ 0.80 | Moderate risk: 0.81–0.85 | High risk: ≥ 0.86
For Indian/South Asian populations (lower thresholds recommended due to genetic predisposition to central obesity): Men: high risk ≥ 0.85. Women: high risk ≥ 0.80.
Apple vs. Pear Body Shape
Apple shape (android obesity, high WHR): Fat concentrated around the abdomen (visceral fat). Higher risk of type 2 diabetes, cardiovascular disease, hypertension, and metabolic syndrome. More common in men and post-menopausal women.
Pear shape (gynoid obesity, low WHR): Fat concentrated in hips, thighs, and buttocks (subcutaneous fat). Lower metabolic risk than abdominal fat. More common in pre-menopausal women.
Visceral fat (apple shape) is metabolically active in a harmful way — it releases inflammatory molecules and free fatty acids directly into the portal circulation to the liver, driving insulin resistance and inflammation. Subcutaneous fat (pear shape), while cosmetically undesired, does not carry the same metabolic risks.
WHR vs. BMI vs. Waist Circumference
Research shows WHR can predict cardiovascular risk independently of BMI. A person with a "normal" BMI but high WHR (thin limbs, protruding abdomen — the "skinny fat" or TOFI — Thin Outside, Fat Inside — profile) faces metabolic risks that BMI alone misses. The combination of BMI, waist circumference, and WHR provides the most comprehensive picture of weight-related health risk.
How to Reduce Waist-to-Hip Ratio
Visceral fat responds very well to lifestyle intervention — often faster than subcutaneous fat. Regular aerobic exercise (150+ minutes per week) is the most effective reducer of visceral fat. Calorie deficit and weight loss broadly reduces visceral fat. Reducing refined carbohydrates and added sugars has particular impact on visceral fat. Stress management (high cortisol promotes visceral fat accumulation). Adequate sleep (sleep deprivation increases visceral fat independently of calorie intake).

Conclusion
Your waist-to-hip ratio is a valuable health screening tool that takes only minutes to calculate with a tape measure. Measure it monthly alongside weight and BMI for a complete picture of your metabolic health trajectory. A falling WHR as you exercise and manage your diet is a meaningful indicator of improved health risk, even when total weight loss is modest.
