How to measure waist-to-hip ratio

Quick answer: To measure waist-to-hip ratio, measure your waist, measure your hips and enter both.

  1. Measure your waist. At the narrowest point, or just above the belly button, breathing out normally.
  2. Measure your hips. Around the widest part of the buttocks.
  3. Enter both. The ratio is waist ÷ hips.

What the numbers mean

The World Health Organization links a ratio above 0.90 for men and 0.85 for women to a higher risk of heart disease and diabetes. Fat around the waist matters more than weight alone.

Frequently asked questions
