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.
Reading the chart the other way, a EU 41cm neck size lands at a UK 16in — the figure to reach for when a European shirt's tag shows only the metric measurement and no inch equivalent at all.
The EU scale steps in whole or half centimetres while the UK scale steps in half inches, so a European neck size sitting between two published EU points is more reliably resolved by measuring your own neck directly in centimetres than by guessing which UK half-size it should round to.
Frequently asked questions
My neck falls between two EU centimetre sizes on a European shirt — what should I do?
Measure your neck directly in centimetres rather than relying on the shirt’s printed EU number, then match that figure to the nearest chart value — for a dress shirt worn buttoned up, round to the nearer size rather than sizing down.
Does the EU-to-UK conversion also work as EU-to-US?
Yes — UK and US collar sizing share the identical inch scale, so a EU size converted to UK here is also the correct US number, without a second lookup.
