Women's jeans chart used: US size = 2 × (W - 25), so W27 = US 4. Then EU = US + 32 and UK = US + 4, and cm = W × 2.54 exactly.
Example
Inputs: Jeans waist size (W) = 28 in. Result: US size: 6; Waist number in cm: 71.1 cm; Letter size: S.
Limits and caveats
- The W number is a label and can differ from your actual waist by several cm depending on the cut and rise.
- Brands vary a lot in jeans, so try on or check the brand chart.
- Covers W25 to W36 only, not W24 and below (US 00).
Questions about this tool
What US size is a W28 jean?
W28 is a US 6 on the common chart, which is a small.
Is W my waist in inches?
Roughly, but it is a label the brand chooses. W28 means 71.1 cm on paper, and the jeans can measure more or less.
Why does the US size jump by 2 for each inch?
US women's sizes are even numbers (4, 6, 8), and each inch of waist matches one of those steps.
