Men's Suit & Sport Coat Fit Guide

There are two essential components when it comes to buying a suit: size and fit. Size is the number inside your jacket. Fit is the overall shape of that particular suit.

Suit and sport coat sizes have one number and one descriptive word (for example, 38 short, 40 regular, 42 long). The number refers to your chest measurement, and the descriptive word refers to the length of the jacket.

Check your own measurements and look for additional size information on the product page to determine which size you should purchase.

Over Arm
With arms at your sides, have someone measure around the broadest part of your shoulders and upper arms.

With arms at your sides, measure around your upper body, under your armpits and over the fullest part of your chest and shoulder blades.

Bend to one side to find the natural crease of your waist. Measure at this point, keeping the tape comfortably loose around your waist.

X-Long (XL) 6'5 1/2" and up

• Tall suits are classified as Long and X-Long (6'2 1/2" and up).

• Big suits are classified as 48 U.S. chest size and up.

• If your over-arm measurement is more than 7" larger than your chest measurement, choose a suit one size larger than your chest.

• Suits have what is called a "drop," which is the difference between the size of the jacket and the size of the pants. Classic-fit suits typically have a 6" drop, meaning that a size 38R jacket is paired with size 32 pants. Trim-fit suits typically have a 7" drop; extra-trim-fit suits usually have an 8" drop.

• Suit makers usually leave enough extra fabric at the seams to allow pants to be let out by 1" to 2". Pants can always be taken in.
