Frequently asked questions
UK 12 and EU 40, typically a letter size M, on standard conversion charts.
In the standard range, UK = US + 4 and EU = US + 32: a US 4 is a UK 8 and EU 36. The offsets are consistent across the chart, which is why a single lookup works.
Men's numeric sizes are chest inches and are the same in the US and UK (a 40 is a 40); the EU size is chest + 10, so a US/UK 40 is an EU 50, usually letter M.
Vanity sizing: brands cut generously or slim relative to the chart, and there is no enforced standard. Convert with the chart, then check the brand's own bust/waist measurements before ordering.
For fitted garments choose the larger row if your bust or waist is at the top of a range; for relaxed styles the nearer row is fine. The converter shows the nearest chart row.
