Waist-to-Hip Ratio Calculator
Calculate your Waist-to-Hip Ratio (WHR) — a clinically validated measure of abdominal obesity and cardiovascular risk. Enter your waist and hip measurements in centimetres for instant WHO risk classification by sex. Free and private.
Key Capabilities
What does waist-to-hip ratio measure?
WHR measures the distribution of body fat. A higher ratio indicates more fat stored around the abdomen (apple shape), which is strongly associated with cardiovascular disease, Type 2 diabetes, and metabolic syndrome compared to fat stored around the hips (pear shape).
What are the WHO WHR thresholds?
For men: Low risk <0.90, Moderate risk 0.90–0.95, High risk >0.95. For women: Low risk <0.80, Moderate risk 0.80–0.85, High risk >0.85. These thresholds are from the World Health Organization (WHO) expert consultation on waist circumference and waist-hip ratio.
Where should I measure waist and hip circumference?
Waist: measure at the narrowest point between your lower ribs and navel, or midway between the two if there is no obvious narrowing. Hip: measure at the widest point around the buttocks. Keep the tape parallel to the floor and breathe normally — do not pull it tight.
