How WHR and risk category are calculated

Waist-to-hip ratio is simply your waist circumference divided by your hip circumference, measured at their widest points. The World Health Organization associates higher ratios with greater risk of cardiovascular and metabolic conditions because they indicate more fat carried around the abdomen relative to the hips — the specific risk thresholds this calculator uses come from WHO guidance and differ between men and women.

Frequently asked questions

According to WHO guidelines, a healthy ratio is below 0.90 for men and below 0.80 for women. Higher ratios are associated with increased health risk.

WHR is used as an indicator of where body fat is stored. Carrying more weight around the waist compared to the hips is linked to higher cardiovascular risk than fat stored around the hips and thighs.
