Waist-to-Hip Ratio Calculator

Waist-to-hip ratio (WHR) is simply your waist circumference divided by your hip circumference, both measured in the same units. It's a screening measure recognized by the World Health Organization for assessing health risk associated with fat distribution, since abdominal ('apple-shaped') fat is more strongly linked to cardiovascular and metabolic risk than fat carried on the hips and thighs ('pear-shaped').

This calculator uses commonly cited WHO risk thresholds: for men, below 0.90 is low risk, 0.90 to 0.99 is moderate risk, and 1.00 or above is high risk. For women, below 0.80 is low risk, 0.80 to 0.84 is moderate risk, and 0.85 or above is high risk.

BMI doesn't capture where fat is distributed on the body, two people with identical BMI can have very different WHR, and therefore very different associated health risk. WHR is best used as a complementary measure alongside BMI, not a replacement for it, since each captures something the other misses.
