Result
This page starts the clothing size converter on the men's dress shirts chart, with the suits and trousers charts one click away: choose the region and collar size you know, and the converter returns the matching size in every other scale in a single row.
Men's conversions are mostly a units story: US and UK shirts share the same collar inches (a 15.5 is a 15.5 in both), while continental Europe labels the same collar in centimetres — 39 — and suits repeat the pattern with chest inches against EU nominal sizes, where a US 40R corresponds to an EU 50. The letters S–XXL are the loosest layer on top: two 'L' shirts from different brands can fit a full size apart, which is exactly the caveat the tool prints under every result.
Everything the full tool offers works here — switch between shirts, suits, trousers and the women's chart, or flip the source and target regions freely. The tables are bundled with the page and each conversion is computed locally in your browser, with nothing sent anywhere.
