Waist-to-Hip Ratio Calculator

Calculate waist-to-hip ratio — a strong predictor of cardiovascular risk.

?What is the Waist-to-Hip Ratio Calculator?

The Waist-to-Hip Ratio (WHR) is a World Health Organization-recommended indicator of abdominal obesity and cardiovascular risk. Large-scale studies — including the landmark INTERHEART study — have shown that WHR predicts heart disease, type 2 diabetes, and early mortality better than BMI alone, because it captures where fat is stored rather than just how much. Belly fat (visceral fat) is metabolically active and dangerous; hip and thigh fat is largely passive and much less risky. Measuring WHR is free, fast, and more clinically informative than stepping on a scale.

The Formula

WHR = Waist Circumference ÷ Hip Circumference. Both measured at their natural contour points, in the same unit.

A simple ratio — but it reveals fat distribution patterns. A high WHR means belly-dominant (apple-shape) fat distribution, which includes visceral fat surrounding the internal organs and is strongly linked to cardiovascular and metabolic disease. A lower WHR indicates hip and thigh (pear-shape) fat dominance, which is predominantly subcutaneous and largely inert metabolically. Simply measuring once with a soft tape measure gives a powerful risk signal that BMI completely misses.

Practical Examples

1

A man with 85 cm waist and 95 cm hip has WHR 0.89 — low cardiovascular risk.

2

A man with 100 cm waist and 95 cm hip (apple shape) has WHR 1.05 — high risk, worth lifestyle intervention.

3

A woman with 75 cm waist and 95 cm hip has WHR 0.79 — low risk.

4

A woman with 90 cm waist and 100 cm hip has WHR 0.90 — high risk by WHO thresholds.

5

A sedentary office worker with apple-shape fat (high WHR) benefits most from cardio exercise and a modest calorie deficit, which reduce visceral fat preferentially.

6

A fit individual with low WHR and normal BMI but with hip-dominant fat can be metabolically healthy even if scale weight is slightly above 'ideal' — shape matters more than weight alone.

Frequently Asked Questions

World Health Organization thresholds: Men — below 0.90 low risk, 0.90–0.99 moderate, 1.0 and above high risk. Women — below 0.80 low, 0.80–0.84 moderate, 0.85 and above high. South Asian populations may benefit from slightly stricter thresholds because cardiovascular risk rises earlier in this ancestry group. Consult your doctor for individualized interpretation.
