How to Measure Waist and Hip

  1. Measure your waist. Use a flexible tape measure at the narrowest point of your torso, typically at or just above the navel. Stand upright, relax your abdomen (do not suck in), and measure after a normal exhale. Take 2-3 measurements and average them.
  2. Measure your hips. Measure at the widest point of your hips and buttocks, usually about 8-9 inches below the waist. Keep the tape level and parallel to the floor.
  3. Enter height (optional). Adding your height enables the waist-to-height ratio, which some research shows is a better cardiovascular risk predictor than WHR alone.
  4. Compare to health thresholds. WHO thresholds: WHR below 0.85 (women) and 0.95 (men) is low risk. Above 0.90 (women) or 1.0 (men) is high risk.

WHR and WHtR Health Thresholds

Waist-to-Hip Ratio = Waist / Hip
Waist-to-Height Ratio = Waist / Height

WHO waist-to-hip ratio risk categories:

Risk LevelWomen (WHR)Men (WHR)
Low RiskBelow 0.80Below 0.90
Moderate Risk0.80-0.850.90-0.95
High RiskAbove 0.85Above 0.95 (some say 1.0)

Waist-to-height ratio (both sexes): below 0.50 is healthy, 0.50-0.59 is overweight risk, above 0.60 is obese risk. Simple rule: your waist should be less than half your height. Waist circumference alone: above 35 in (89 cm) for women and 40 in (102 cm) for men indicates elevated risk.

Frequently Asked Questions

According to the World Health Organization, a healthy WHR is below 0.85 for women and below 0.95 for men. Ratios above these thresholds indicate abdominal obesity, which is associated with higher cardiovascular disease, type 2 diabetes, and metabolic syndrome risk. For example, a woman with a 32-inch waist and 38-inch hips has WHR = 32/38 = 0.84 (low risk). The same woman with a 36-inch waist would have WHR = 36/38 = 0.95 (high risk).
