Waist-to-Hip Ratio Calculator

Waist to hip ratio, which measures fat distribution rather than quantity. Abdominal fat is more strongly associated with metabolic risk than the same amount carried on the hips.

Also called: whr calculator, waist hip ratio.

0.92, which is above the threshold associated with higher metabolic risk. Measured against the WHO general threshold, 0.9 for this sex. Losing 2 cm from the waist would reach it. 1 of 2 abdominal measures are above threshold: waist to hip. Agreement between them matters more than any single reading. The ratio measures where fat sits rather than how much. Abdominal fat carries more metabolic risk than the same amount on the hips.

On the threshold used
Measured against the WHO general threshold, 0.9 for this sex.
Against the other measures
1 of 2 abdominal measures are above threshold: waist to hip. Agreement between them matters more than any single reading.
On fat distribution
The ratio measures where fat sits rather than how much. Abdominal fat carries more metabolic risk than the same amount on the hips.

Method and background

This is what the calculation gives for the numbers you entered. It is an estimate, not advice, and it knows nothing about your situation beyond those numbers. Rules for India change on a published schedule; the effective date is shown on every rule-based tool.

How this is calculated

The ratio captures where fat is stored. Visceral fat around the abdomen is metabolically active and associated with cardiovascular and metabolic risk in a way that subcutaneous fat on hips and thighs is not, which is why two people at the same BMI can carry very different risk. Thresholds are 0.90 for men and 0.85 for women in the WHO classification, though they vary between populations.

Method and limits

What it assumes

  • Waist measured at the narrowest point and hips at the widest.

What it deliberately does not model

  • Measurement site varies between protocols, which changes the ratio.
  • Thresholds differ by population, and South Asian populations carry risk at lower values.
  • Waist to height ratio predicts outcomes at least as well and needs one fewer measurement.

Frequently asked questions

Why does fat distribution matter?
Visceral fat around the organs is metabolically active in a way that hip and thigh fat is not, so two people at the same weight can carry very different risk.
