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 British collar size converts to EU centimetres through the same inches-to-cm arithmetic used elsewhere on this site's shirt chart — a UK 16in lands at a EU 40cm — since the UK scale is itself just the US inch scale under a different flag, not a separate system in its own right.
This specific direction matters mainly for a UK shopper buying from a continental European shirtmaker whose site lists collar size only in centimetres, with no inch figure offered at all — worth noting that a lot of European dress-shirt lines also default to a slimmer body cut than mainstream British tailoring, so a correctly converted neck size can still feel closer through the chest than a familiar UK brand.
Frequently asked questions
Is UK-to-EU shirt sizing the same conversion as US-to-EU?
Yes — the UK neck scale is identical to the US one, so the same inches-to-centimetres arithmetic applies regardless of which of the two you are starting from.
Will a EU shirt at my converted size fit the same as my usual UK shirt?
The collar should match, but check the cut — a lot of continental European dress shirts default to a slimmer body silhouette than mainstream British tailoring, independent of the neck-size conversion itself.
