How to Find Your Suit Size


The first thing you need to know is that suit sizes are based on chest measurements.
Ex: If your chest measures 42", you should purchase a 42 suit.


The waist size of the pants that come with your suit will be approximately 6"-7" less than your jacket. This is known as the drop. A 42 suit = size 36 pants approximately.


Please see the chart below to determine your correct jacket length.

Suit Length*
Short (S)
Regular (R)
Long (L)

5'4” – 5'7”
5'7.5” – 5'11”
5'11.5” – 6'2.5”


Pants are unhemmed so you will need to have them tailored.

* May vary slightly by brand.

– See below for a quick how-to on measuring –

a. CHEST: Wrap tape measure around your torso – be sure to go underneath your arms, across your shoulder blades & over the largest part of your chest.

b. WAIST: Loosely hold a measuring tape around your natural waistline. Your natural waistline is above your belly button and below the start of your rib cage.
