The top men's size here, a 131 cm chest at EU 62 and UK 52, marks the second XXL before sizing moves to dedicated big-and-tall labels.
Brand fit: Just 3 cm below the XXL ceiling of 134, a 131 cm chest grades tight in a standard 52, while big-and-tall blocks add width through the chest and length in the body.
Availability: At the top of a standard chart, a 52 chest is stocked mainly by big-and-tall specialists; general ranges usually stop below it, so expect more choice and better fit from dedicated labels.
UK to US conversion
British and American men's jacket sizes are the same number, so UK 40 is US 40 and UK 46 is US 46 with nothing to convert. Both label the chest in inches, which is why the columns match and the site keeps a single page for the pair rather than a reverse. The catch is that neither number is tightly standardised, so a UK 40 and a US 40 from two makers can each measure a couple of inches off the nominal chest.
At this size, UK to US
One size down from UK 52, US moves 2 to US 50 while UK falls 2 to UK 50, holding their spacing. Both UK 52 and US 52 are whole numbers here, so nothing rounds. For UK 52, the US column here runs US 48, US 50, US 52, stepping two numbers at a time.

Frequently Asked Questions Does UK 52 round up or down in US? At the last size, round up and budget for alterations; standard grading stretches thin here, so the chest fit matters more than the number on the label.
