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 4 sits at a EU 37 on the standard women's chart, and the two systems climb in step from there — UK 3 through UK 8 map onto EU 35.5 through EU 40.5 with no irregular jumps in this range.
Because UK sizing is a whole-number scale and EU sizing moves in half-point steps, a UK size never needs rounding to find its EU match; the reverse direction (EU to UK) is the one where a shopper occasionally has to pick between two adjacent UK sizes.
Frequently asked questions
Is UK-to-EU shoe conversion ever ambiguous?
Not on the standard table above — every UK half or whole size lands on exactly one EU value. Ambiguity shows up more often going the other way, EU to UK, where a factory's EU labelling can round differently.
