Waist-to-Hip Ratio Calculator

Calculate your waist-to-hip ratio (WHR) and assess cardiovascular risk. Uses WHO risk classification for men and women.

Measure waist at the narrowest point (above the navel, below the ribcage). Measure hip at the widest point across the buttocks.

WHO Risk Classification

Risk Category	WHR (Male)	WHR (Female)	Your Status
Low Risk	< 0.85	< 0.80
Moderate Risk	0.85 – 1.0	0.80 – 0.85	← You're here
High Risk	>= 1.0	>= 0.85

Slightly elevated cardiovascular risk. Consider lifestyle improvements.

Waist circumference risk thresholds (WHO): Men — moderate risk: 94cm, high risk: 102cm. Women — moderate: 80cm, high: 88cm.

Waist-to-Hip Ratio Calculator — WHO Risk Classification

Waist-to-hip ratio (WHR) is a measure of body fat distribution and is strongly associated with cardiovascular disease, type 2 diabetes, and metabolic syndrome risk. Formula: WHR = Waist circumference / Hip circumference. WHO classifications: Low risk in men: WHR < 0.85; women: < 0.80. High risk: men ≥ 1.0; women ≥ 0.85. The waist-to-height ratio (WHR ≤ 0.5) is another useful predictor — keeping your waist to less than half your height is a simple health target. Unlike BMI, WHR accounts for where fat is distributed: abdominal (apple-shaped) fat carries significantly higher risk than hip/thigh (pear-shaped) fat.
