Example
Inputs: EU or Italian size = 52. Result: US and UK size: 42; Letter size: L; Chest girth it refers to: 104 cm.
Limits and caveats
- The difference of 10 is the common chart; some French brands shift by one size.
- The chest figure is the body girth under the German convention, not the garment.
Questions about this tool
What is an Italian 52 suit in US size?
An Italian 52 matches a US and UK 42.
Why is the EU size half the chest?
German charts set the jacket size at half the chest girth in cm, so size 50 fits a chest of about 100 cm.
Is Italian sizing the same as German?
For men's suits both charts usually use the same numbers, though Italian cuts can run slimmer.
