Waist-to-Hip Ratio Calculator
Calculate your waist-to-hip ratio, a measure used to assess health risk associated with body fat distribution.
Why waist-to-hip ratio matters
Where the body stores fat matters as much as how much fat is stored. Fat carried around the abdomen (sometimes called 'apple-shaped' distribution) is more strongly associated with cardiovascular and metabolic health risk than fat carried around the hips and thighs ('pear-shaped' distribution) — which is what makes WHR a useful complement to BMI.
The World Health Organization uses WHR thresholds that differ by sex, reflecting natural differences in typical fat distribution between men and women.
Measuring waist and hip correctly
Waist circumference is typically measured at the narrowest point of the torso, usually near the navel, while standing relaxed (not sucking in). Hip circumference is measured at the widest point around the buttocks.
Consistency matters — measuring at the same time of day, in similar conditions, and at the same landmarks each time produces more meaningful comparisons than one-off measurements taken differently.
Frequently asked questions
Is waist-to-hip ratio better than BMI?
They measure different things — BMI reflects overall weight relative to height, while WHR reflects fat distribution. Many health professionals consider them complementary rather than one replacing the other.
Why do risk thresholds differ between men and women?
Natural body fat distribution differs by sex on average, so WHO and other health organizations set separate risk thresholds calibrated to typical patterns for each.
