Why Waist‑to‑Hip Ratio Matters More Than BMI

Research consistently shows that where you carry fat is a stronger predictor of health risk than how much you weigh. Abdominal fat (the "apple" shape) is metabolically active and linked to higher rates of heart disease, diabetes, and stroke. Hip and thigh fat (the "pear" shape) is comparatively protective. This calculator uses WHO guidelines to categorise your ratio and explain what it means.

Two measurements, one number, a wealth of insight. Pair this with your BMI and Body Fat % for a complete picture.
