Waist-to-Hip Ratio Calculator
Calculate waist circumference divided by hip circumference locally, using centimetres or inches. Adult screening estimate only, not a diagnosis. Interpretation depends on population and measurement method. Display rounding does not imply measurement accuracy.
A QUICK WALKTHROUGH
How to use this tool
- Enter waist and hip circumferences in the same unit.
- Choose Calculate to view the unitless ratio.
- Copy the result or reset the measurements.
Formula and units
Formula: waist circumference ÷ hip circumference. The ratio has no unit. Use the same unit for both measurements. Accepted range: 0.1–500 cm, or the equivalent in inches. Changing units converts the entered measurements (1 in = 2.54 cm).
Interpretation limits
Adult screening estimate only, not a diagnosis. Interpretation depends on population and measurement method. Display rounding does not imply measurement accuracy.

GOOD TO KNOW
Common questions
Does this result mean I am healthy?
No. A ratio alone cannot establish health, and this tool does not assign clinical risk categories.
