How to use this calculator

  • Measure waist at the narrowest point (typically just above the navel), tape parallel to the floor, relaxed.
  • Measure hips at the widest point of the buttocks.
  • Take both measurements in the morning, before eating.
  • Use the same units for both (mixing units gives wrong ratio).

About this tool

Where you carry fat matters as much as how much you carry. Waist-hip ratio (WHR) is one of the simplest indicators of central (visceral) obesity, which is more strongly linked to heart disease, type 2 diabetes, and metabolic syndrome than overall fat. WHO thresholds: men should aim for <0.95, women <0.80. Above 1.0 (men) or 0.85 (women) is considered substantially elevated risk. Pair WHR with BMI for a fuller picture: someone with normal BMI but high WHR ("skinny fat") still carries elevated risk.

Frequently asked

BMI doesn't distinguish where fat sits. Visceral fat (around organs, near the waist) is metabolically active and dangerous. Subcutaneous fat (especially on hips/thighs) is less risky. WHR captures this distribution.
