Waist-to-Hip Ratio Calculator

Calculate your waist-to-hip ratio (WHR) to assess cardiovascular and metabolic health risk. Get your body shape category, WHO risk classification, and personalized health insights.

Based on WHO & NIH guidelines — WHR is a stronger cardiovascular risk predictor than BMI alone

Body Measurements

Measure at the narrowest point of your waist and the widest point of your hips

Measurement Units

Measure at the narrowest part, usually just above the belly button

cm

Measure at the widest part of your hips and buttocks

Biological Sex

Used to apply the correct WHO risk thresholds (thresholds differ by sex)

How to Measure Correctly

Accurate measurements are key — small errors shift your risk category

Waist
  • • Stand upright, feet together
  • • Exhale normally — don't suck in
  • • Measure at the narrowest point (usually 1–2 cm above navel)
  • • Tape should be snug, not tight
  • • Take 2–3 readings and average them
Hips
  • • Stand with feet together
  • • Measure at the widest point of hips/buttocks
  • • Keep tape parallel to the floor
  • • Don't compress the skin
  • • Take 2–3 readings and average them

Body Shape Guide
Apple (Android)Higher WHR

More weight around the abdomen. Associated with higher cardiovascular risk.

Pear (Gynoid)Lower WHR

More weight around hips and thighs. Generally lower cardiovascular risk.

Hourglass / BananaNear 1.0 WHR

Balanced proportions or straight silhouette. Risk depends on absolute measurements.

Why WHR Matters
Better than BMI alone — WHR captures fat distribution, not just total weight. Abdominal (visceral) fat is metabolically more dangerous than subcutaneous fat.
Cardiovascular predictor — Visceral fat releases inflammatory cytokines linked to insulin resistance, type 2 diabetes, hypertension, and heart disease.
Trackable over time — Unlike BMI, WHR can improve meaningfully with targeted lifestyle changes within weeks, even before visible weight loss.
