Suit Size Chart & Suit Size Calculator

If you need to find your suit jacket and pant sizes without a measuring tape, our men’s suit size chart is a good place to start.

This man used a suit size chart or suit size calculator to find his suit size.

Look. Using a men’s suit size chart isn’t always going to result in a perfect fit. It can, but remember: we’re not baking, we’re cookin’, baby. There are variables, and finding your suit sizes is a nuanced business that a single chart cannot accomplish.

Still, the suit size chart you’ll find below does a good job of getting you in the neighborhood. We also developed a suit jacket size chart specifically for finding the right jacket length, and our own suit size calculator—the most accurate way to find your suit sizes without actually trying the thing on. Let’s get your fit together.

Suit Size Chart: Jacket, Pants, & Dress Shirt Size Chart

Most of us know our casual clothing sizes—small, medium, large, whatever. Using a suit size chart conversion from your casual clothing sizes is a quick and dirty way to estimate your dress shirt neck, suit jacket chest and sleeve, and suit pant waist sizes for a suit or tuxedo.

This assumes you have the average, standard build. And no offense, but that is unlikely—people have a variety of body shapes and body types. That’s why suit size charts—even this one—are best used for finding a ballpark number for your suit sizes. They’re foolproof, but less likely to deliver a perfect fit than say, a suit size calculator.

How to Read Suit Sizes

Need help understanding any of the letters or numbers on the suit size charts above? Congrats! You are exactly where this mixed-up universe wanted you to be. Let’s break it down by size.

Suit and tuxedo jackets are sized in numbers, typically between 34 and 52, plus a letter or two. These numbers relate to the chest size of the jacket (but not your chest measurment), and typically offered in even sizes.

Jackets come in short (S), regular (R), and long (L) lengths, with some brands offering extra short (XS) and extra long (XL) lengths, too. These lengths are usually determined by your height.

The first number on the pant label is the waist size, while the second is the length (AKA the inseam). Suit pants won’t always list a length—suit pants are often hemmed to length nirvana anyway—but you’ll always have a waist size on the tag. Waist sizes tend to come in even sizing (32, 34, 36, etc.), and if a suit pant inseam is offered, it’ll probably come in even sizes, too.

Casual clothing tends to stretch more in places where a suit would not, like the waist. That means your suit pants, which have less give, will likely need to be a larger size than your favorite pair of denim.

But while your waist size number might seem higher than usual, the length number is likely to be a lower (and shorter) number than your jeans. Why? The fabrics used for suit pants don’t bunch up as easily as casual fabrics, so they fit longer. Keeping that pant length in check is important for a modern fit.

tl;dr: Suit pants tend to fit tighter and longer than casual pants of the same size.

Using a suit jacket size chart can help you find the proper fit.

Sizing from brand to brand can vary—think +/- a size or length. Don’t let this stop you from shopping a variety of suit brands, but keep it in mind if you do your shopping online—ordering the tag size may not equate to an identical fit.

That’s often why a suit size calculator (like the one we developed) could provide a sizing recommendation that differs from what you might expect.

Suit Size Calculator

The word “calculator” makes me think of too many buttons, and in the world of suits, any more than three buttons is insanity (looking at you, Steve Harvey). But a real suit size calculator does exist, has relatively few buttons, and works better than a suit size chart. At least, ours does.

We ask you simple questions that you probably already know the answers to: height, weight, age, body shape, and shoe size. If you have a particular fit preference (slim, classic, etc.) or know any of your formalwear sizes (your dress shirt or pant size, for example), we’ll use that info, too. If not, that’s fine. Then, using the sizing data gathered from hundreds of thousands of customers, our suit size calculator provides the most probable sizes for your perfect fit.

Or, Just Try On a Suit (For Free)

Our calculator is more reliable than any suit size chart, but sometimes you just want to try the damn thing on in the flesh and fabric. That’s why we have over 300 showroom locations across the country where you can choose your look and dial in the fit.
