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 UK 12 dress converts to a EU 40 on the standard chart, with the EU number running two points above the UK number all the way through this range (UK 4 to EU 32, UK 20 to EU 48).
That fixed two-point gap makes UK-to-EU dress conversion the most arithmetically predictable of the four regional dress pairs on this site, though cut and brand still matter more than the size number for anything fitted rather than loose.
Frequently asked questions
Is the UK-to-EU dress gap always exactly two points?
On the standard published table shown here, yes — every UK size on this chart is exactly two EU points below its EU match. Individual brands can still cut generously or tightly within that labelled size.
