Sizing Questions, Answered
How do I convert a US suit size to an EU suit size?
Add 10 to your US or UK suit size to get the equivalent EU size. A US 40 jacket is a EU 50.
Is a US suit size the same as a UK suit size?
Yes. US and UK men's suit and tuxedo sizing both run on the same chest-based numbering system.
How do I measure my chest for a suit jacket?
Wrap the tape under your arms, across the fullest part of your chest and shoulder blades. Keep it level and snug, not tight, and measure over a light shirt.
What do the letters S, R, and L mean on a suit size?
Short, Regular, and Long describe jacket and sleeve length based on your height — not chest width. Choose the length that matches your height range for the best fit.
