Men’s Guide – Find Your Size

Below you will learn how to properly find your US sizes for suit jackets, blazers, and coats, as well as your Letter Size.

First, you need to find your correct measurements.  When you have finished, come back here to find your correct US sizes. Men’s US sizes for suit jackets, coats and blazers are based on chest width and height. When you measure your chest, be sure to stick a finger between the measuring tape and your body. The result will be your jacket size.

Depending on your height, you will be either a short (S), regular (R) or long (L). Once you have taken your measurements, use the table below to find your clothing size in US Letter Sizes (Small/Medium/Large/etc).
