Sizing conventions vary by brand and by cut — this table shows the standard published conversion. Always check the garment's own size chart when one is available. See how these tables are compiled.

A EU 52 suit converts to a US/UK 42 on the standard chart, the reverse of the ten-point gap seen going US to EU — the number needed when a European tailoring brand's chart lists only the EU size.

Because US and UK suit sizing use the same chest-inch number, this same figure works equally as a EU-to-UK conversion, leaving only drop and cut (not the base chest number) to check against the specific brand.

Frequently asked questions

Does this EU-to-US suit conversion also work for UK sizing?

Yes — US and UK suit sizes share the same chest-inch number, so a EU size converted here gives the correct UK size as well, without a separate lookup.
