How the conversion works
European tailors size jackets by half the chest circumference in centimeters, so a European 50 does not mean what an American 50 means. If you are buying an Italian or German blazer from a US store (or vice versa), this converter translates the number for you.
Add 10 to the US size to get the EU size: a US 38 is an EU 48, and a US 42 is an EU 52.
Getting the right fit
EU sizing is based on the chest circumference in centimeters divided by two, rounded to an even number. Measure your chest in centimeters, divide by two, and you have your EU size directly, with no conversion needed. European cuts are often slimmer than American ones, so many shoppers go up one size.
Frequently asked questions
What is a US 40 jacket in European sizes?
A US 40 is an EU 50, based on a chest measurement of about 102 cm. Many European brands cut slimmer than American ones, so consider sizing up if you prefer a relaxed fit.
Are these size conversions exact?
No. Clothing and shoe sizes are conventions rather than measurements, and every brand cuts its garments a little differently. Treat the result as a reliable starting point, then confirm with the retailer's own size chart and customer reviews.
What should I do if I am between two sizes?
Compare your body measurements against the brand's chart. If you are still undecided, choose the larger size for a relaxed fit or if the item does not stretch, and the smaller size if the garment is stretchy and you prefer a snug fit.
