Why Waist-Hip Ratio Matters

WHR = waist circumference ÷ hip circumference. It captures where fat sits — abdominal fat carries higher cardiometabolic risk than hip/thigh fat. WHO thresholds for substantially increased risk: ≥0.90 for men, ≥0.85 for women. Measure the waist at the narrowest point (or navel) and hips at the widest, tape parallel to the floor.

Informational only — interpret alongside BMI, waist circumference and a clinician's advice.

Frequently Asked Questions

Which is better, BMI or WHR?

They answer different questions: BMI screens overall mass, WHR screens fat distribution. A muscular person can have high BMI with a healthy WHR; an "apple-shaped" normal-BMI person can carry risk WHR reveals.

How do I measure correctly?

Stand relaxed, exhale gently; waist at the narrowest point between ribs and hip bone, hips at the widest part of the buttocks. Keep the tape snug and level.
