Today we’ll be taking a look at suit sizes for men. We explored suit jacket sizes in our article on how to understand a suit size chart, and we’ve filled you in on dress shirt sizing too. We’ve also taken an in-depth look at how to get perfect suit measurements for each body part.

Using a suit size chart conversion from your casual clothing sizes is a quick and dirty way to estimate your dress shirt neck, suit jacket chest and sleeve, and suit pant waist sizes for a suit or tuxedo.

Suit and sport coat sizes have one number and one letter (for example, 38S, 40R, 42L). The number is your chest measurement and the letter refers to the jacket's length ’ short, regular or long. Check your own measurements and follow our men's suit size chart to help determine the right size for you. Shop Men's Suits.

Whether you need to know how to measure for a suit yourself, or you need tips for having your measurements taken, we can help you find your suit size.
