How it works

Calculates waist-to-hip ratio (WHR) and flags elevated cardiometabolic risk by sex-specific cutoffs.

Who it's for: Adults assessing central obesity beyond BMI, especially those with normal BMI but abdominal fat.

WHR = waist circumference ÷ hip circumference (both in inches).

Uses NIH/WHO thresholds: elevated risk at WHR ≥ 0.90 (men) or ≥ 0.85 (women).

Central fat distribution correlates with type 2 diabetes and cardiovascular risk independent of BMI.

How to use

  1. Select Sex.
  2. Measure Waist in inches at the navel (standing, relaxed, at end of normal exhale).
  3. Measure Hips in inches at the widest part of the buttocks.
  4. Read WHR rounded to two decimals.
  5. Check Risk — Normal or Elevated based on sex-specific cutoffs.
  6. If Elevated, discuss lifestyle changes with your primary care provider.

Good to know

  • Measure with a flexible tape parallel to the floor — do not pull tight enough to compress skin.
  • WHR complements but does not replace waist circumference alone (≥40 in men, ≥35 in women is high risk).
