Measure Your Waist for Your Pant Size. To find your waist measurement for suit pants, first bend to the side to find your natural crease. Measure around your waist at this point, making sure to keep the tape comfortably loose by keeping two fingers between the measuring tape and your body.
Buying the right size suit jacket makes the difference between being uncomfortable and feeling good. When you feel good, you will look good and portray confidence and calm to others, which can be important both at work and in social situations.

Have a fabric measuring tape, paper and pen ready. Stand flat footed with your arms flat at your sides. Take a chest measurement first by having your assistant place the measuring tape around your chest, just beneath your armpits and underneath your arms. Drape the tape around the chest in a circle going over the shoulder blades on your back. Ask your assistant to write down the number, in inches, as your chest measurement. Take an overarm measurement by standing flat footed with your arms resting against your sides.

Have your assistant place the tape measure over the outside of your upper arms across the thickest part of your chest. Write this number down, in inches, as your overarm measurement. Note that the overarm measurement is sometimes referred to as the shoulder measurement. Subtract seven inches from your overarm measurement to get an O-chest measurement. Compare the O-chest measurement with your first chest measurement and retain the larger of the two measurements.

Or maybe you have a sport coat with a European size and want to convert that to a US size? Then this guide is for you! Both buyers and sellers want to be sure clothing bought online fits.

Memorize the measurements and always have them when you are shopping online. If you are a Seller, please bookmark, share, and reference this guide often. Here is how to take each measurement, followed by a worksheet to convert these measurements to standard US sizes. The chest determines the size of the jacket and it is very difficult to alter a jacket to fit properly if the chest is wrong. This is how you measure the chest: Smooth the jacket body so the fabric has no ridges or creases and the lapels are flat.

You want to measure the full amount of fabric but not pull it so far as to distort the jacket beyond the shape it should be when worn properly. Measure across the chest from the side seam at one underarm across to the side seam at the opposite underarm.

Add a caption Measure from underarm to underarm with jacket lying smooth and flat. This is shown in the Example and the worksheet below.

The jacket in the photo above measures 25 inches from underarm to underarm. To allow for ease of movement, I will subtract 4 inches. My jacket is a US Size 46!

The rule of thumb of 4 inches is for a "classic fit" jacket - a "slim fit" or close-fitting jacket might have just 2 inches of ease. Keep the jacket as it was for the chest measurement and measure the waist, which is usually about midway between the underarm and the top of the pockets and usually near the second button from the bottom. High-end suits tend to have a waist about 2 inches smaller than the chest.

The jacket in the photo is 24 inches across the waist. This does not mean the man who wears this suit has a waist that measures 48 inches! The waist of a jacket also needs to allow ease of movement to accommodate the man, his trousers, and a shirt.

To get your next two measurements, flip the jacket over so the back of the jacket is facing you. To measure the length, start at the base of the collar at the seam where the collar joins the coat back.

The European size of a suit is 10 more than the US Size. For example, a size 50 (European) is equivalent to a size 40 (US). Typically the waist size of a suit pant is 6" less than the suit size. For example, a suit size 42 jacket comes with a 36" waist pant. There are two essential components when it comes to buying a suit: fit and size. Fit is the overall shape of that particular suit.
