About Clothing Sizes
Turn a chest/bust measurement into alpha, US numeric, and EU sizes for men’s and women’s fits.
Enter the chest (men) or bust (women) measurement in inches and the fit. The tool maps it to an alpha band (XS–XXL), a US numeric size, and the EU suiting number, plus the metric equivalent.
These are industry-standard approximations — vanity sizing and brand cuts shift real garments by a full size, so confirm against the specific brand chart for fitted clothing. Everything runs in your browser.
Where it is used
Ordering international clothing, checking size charts quickly, and converting tailor measurements.

Frequently Asked Questions
- Why do brands disagree with the chart?
- Vanity sizing (labeling larger to flatter) and different target bodies shift garments a full size or more. Charts standardize; brands deviate.
- Men’s vs women’s for the same chest?
- Different cuts and grading: a 40-inch chest reads M in menswear but L in womenswear, with different shoulder and waist shaping.
- How should I measure my chest?
- Tape around the fullest part, level all around, relaxed breathing, over a thin shirt. Measure twice; bodies are not symmetric front-to-back.
