How to Measure Men's Suit Size

When the goal is to buy a men’s suit off the rack, it is a good idea to take a few measurements first. This action will help to ensure that the selected suit will have a comfortable general fit that requires little or not alterations. Fortunately, even a novice can take accurate measurements and thus set the stage for purchasing a suit that will fit properly.

Difficulty: Moderately Easy

Instructions

1. Begin the process by measuring the chest. The proper way to do this is have the gentleman raise the arms slightly. A position with the elbows level with the shoulders is sufficient. Position the tape measure so it crosses over the shoulder blades of the back and at the thickest portion of the chest, usually across the breast area. Suits are usually sized according to this measurement, so if the gentleman has a 40 inch chest measurement, he will wear a size 40 suit.

2. Measure the arm length. This is accomplished by having the gentleman lower the arm to his side, and cup the fingers into a light grip. Measure from the shoulder to the tips of the fingers in the grip position. Pre-tailored suits are usually sold as shorts, longs, and regulars. The arm measurement helps to determine which of these three designations will be most appropriate for the jacket.

3. The waist for the pants is the next measurement to take. Be sure to measure at the waist position that the gentleman normally wears the pants. In general, the waist size on a pre-made suit will be six inches less than the chest measurement. Knowing the actual waist size in advance will provide some idea of how much tailoring needs to be done in order to make the pants a perfect fit around the waist.

4. Finally, measure the legs for the pants. Many pre-made suits do not come with a finished hem, which makes it possible to alter the pants to fit the height of the buyer. First, take the outside leg measurement by beginning at the waist and measuring to the area just above the heel. For the inside leg measurement, begin at the crotch and measure to the ankle bone. These two figures should result in a hem that will break properly over the top of the shoes without puddling.

5. Have him try on things, and make sure the measurements are accurate.

Tips & Warnings

• Make sure to write down all measurements as they are taken.
• Take the list along on the shopping trip. It will save a lot of time and effort.
• Always try on a suit before making a final selection and purchase. The actual cut of the suit may impact how the material settles on the frame and require that the measurements be used more as a guide rather than a final determination.
