Example
Inputs: US or UK jacket size = 42 in. Result: EU and Italian size: 52; UK size: 42; Letter size: L.
Limits and caveats
- This is the chart most stores use; some French and Japanese brands number their suits differently.
- The letter size comes from a common US chart and can shift with the cut.
Questions about this tool
What is a US 40 suit in EU size?
A US 40 matches a 50 on European and Italian charts, since the two differ by a fixed 10.
Are UK and US suit sizes different?
No. Both give the chest in inches, so a UK 40 is a US 40.
What do S, R and L after the number mean?
They mark jacket length: short, regular and long. They do not change the EU number.
