About Clothing Sizes

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.

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.
- US number?
- Mens US ≈ chest-2, womens US ≈ (bust-26)/2. EU suit ≈ chest+10.
- Between sizes?
- Size up for comfort, down for fitted. Check brand chart before ordering.
- Private?
- Yes. Math runs locally.
