Suit Jacket Size Calculator

- US jacket size
-
Length
-
EU size

Determine your suit jacket size from your chest measurement and height. A jacket size is essentially your chest circumference in inches, so a 40 inch chest is a size 40, and a letter for length: short, regular or long, chosen from your height so the hem and sleeves fall correctly. Measure around the fullest part of your chest under the arms with the tape level, and enter your height so the tool can suggest the right length code. It returns your numeric US jacket size, the equivalent European size, and the length letter such as 40R or 42L. Drop, the difference between jacket and trouser size, is usually six inches for a regular build, which you can use to estimate matching trousers. Fit at the shoulders is hard to alter, so start from this size and tailor the waist. Everything runs in your browser and updates instantly.
