Waist-to-Height Ratio Calculator

💡 Why Waist-to-Height Ratio Matters

WHtR = waist circumference ÷ height. The simple rule: your waist should be less than half your height (WHtR < 0.5). This single metric predicts cardiovascular risk, type 2 diabetes, and metabolic syndrome better than BMI alone.

WHtR < 0.4: underweight/underfat. 0.4–0.5: healthy. 0.5–0.6: overweight/increased risk. > 0.6: obese/high risk. Unlike BMI, it works across all ages (children and adults) and ethnicities without adjustment.
