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.
Reference Table
| Value | Meaning |
|---|---|
| Higher WHR | More central fat pattern (screening) |
| Tape technique | Stand relaxed; measure at narrowest waist, widest hip |
| Population cutoffs | Vary; follow clinician guidance |
FAQ
Is WHR better than BMI?
It adds shape information; neither replaces clinical assessment.
Postpartum?
Waist changes are gradual; compare trends over months.
Men vs women?
Risk associations differ; use appropriate reference ranges.
Clothing?
Measure against skin or thin clothing for consistency.
