What is this calculator?

Compare waist and hip circumferences as a simple shape metric. The formula, a worked example, and a reference table are below. Results are for education only, not medical advice.

How it works

WHR = waist circumference ÷ hip circumference (same units, e.g., cm/cm).

Example

Waist 85 cm, hip 102 cm WHR ≈ 0.83.

Men vs women?

Risk associations differ; use appropriate reference ranges.

Clothing?
