Measurement: Men

Before You Begin

To find your size, find a two-button blazer that fits you well, and follow the instructions on this page. Select the class jacket size that is closest to your measurements. Our recommendation is to size up if in doubt, as it is easier to take in than to take out. Other notes: 

  • This is a modern trim fit blazer, so if you prefer a roomy jacket, go up a size for comfort. For example, if you generally buy a standard fit suit in 40 Reg, we might suggest ordering a 42 Reg for your 25th Reunion Class Jacket.
  • Remember, you will have this jacket for a long time, so plan for the future when sizing your jacket. If you’re concerned that your size may fluctuate over time, consider buying an extra jacket during the registration process.
  • If you plan to tailor your jacket, it is much better to order a larger size and take it in. There is some extra fabric at the seams inside the jackets, so while it’s possible to let out the jacket on the sides and lengthen the sleeves, we don’t recommend it.

How to Measure

Note: The images below are for example purposes only and are not indicative of 1997’s 25th Reunion Class Jacket.

Step A: Chest

  1. Lay blazer on flat surface. Button top button of jacket and smooth out any wrinkles or folds.
  2. Lay tape measure flat across chest of jacket 1” below armholes per picture (do not pull tape measure tight).
  3. Take this measurement and and double it.
  4. Write down this chest measurement and move to Step B (Waist).

Alternative Option for Chest

If you don’t have a blazer available, use this alternative.

  • Using a tape measure, measure chest just under arms and across shoulder blades, holding tape level. The tape measure should be parallel to the floor. It may be easier to have someone else hold the tape.
  • Don’t hold your breath.
  • Be sure to cross over the shoulder blades and the fullest part of your chest.
  • Skip to Step F.

Step B: Waist

  1. Lay down jacket on a flat surface.
  2. Measure from the center seam of the jacket to the front edge of jacket (past the button or button hole).
  3. Take this measurement and double it.
  4. Write down this waist measurement and move to Step C (Shoulder).

Step C: Shoulder

  1. Lay jacket on a flat surface.
  2. Measure from the point where the shoulder seam meets the top of the sleeve from one side to the other. Do not pull the tape measure tight.
  3. Write down this shoulder measurement and move to Step D (Back).

Step D: Back

  1. Lay jacket face down on a flat surface.
  2. Measure from the base of the collar all the way down to the bottom end of the jacket.
  3. Write down this shoulder measurement and move to Step E (Chart).

Step E: Use the Chart

Using the measurements from the previous steps, find your size using the chart below. Please note:

With regards to length, use the Back measurement to pick Short, Regular, or Long length. Typically, your height is a good check against this parameter:

  • Up to 5’ 6” = Short
  • 5’ 7” to 5’ 11’ = Reg
  • 6’ to 6’ 2” = Long

Sleeve measurements are for informational purposes only and should not factor into your size. You are ready to place your order.

Sizing for Men (Body Measurement)

Step F: Determine Your Size

If you do not have a jacket to measure, simply take your Chest measurement and that is your size. For example, if you have a 38″ chest, you would wear a size 38 blazer.

For length, use your height as a proxy.

  • Up to 5’ 6” = Short
  • 5’ 7” to 5’ 11’ = Reg
  • 6’ to 6’ 2” = Long
