How Are Men's Dress Shirts Sized: Understanding the Intricacies of Perfect Fit

In the world of men's fashion, there's nothing more quintessential than the classic dress shirt. Whether you're attending a business meeting, a formal dinner, or just enjoying a night out, a well-fitted dress shirt can make a world of difference. But what exactly goes into sizing men's dress shirts? How can you ensure that you're wearing the perfect size for your unique body shape and size? This guide will delve deep into the process of sizing men's dress shirts and provide you with actionable steps to determine your perfect fit.

Decoding the Sizing System

Contrary to popular belief, sizing men's dress shirts goes beyond the typical small, medium, and large labels. It's a comprehensive system that considers various measurements including your neck size, arm length, chest width, and waist circumference.

The sizing system for men's dress shirts is typically expressed in two numbers. The first corresponds to the neck size, while the second pertains to the sleeve length. For instance, a size marked as "15.5, 34/35" means the neck size is 15.5 inches, and the sleeve length falls between 34 and 35 inches.

Understanding this sizing system is critical for a couple of reasons. For one, it provides a better fit than standard sizes. Moreover, it offers a greater range of sizes, which means you're more likely to find a shirt that fits you perfectly.

Step-by-step Guide to Measuring Men's Dress Shirt Sizes

Now that we've explored the sizing system, let's go through the process of measuring for men's dress shirt sizes. Remember, accurate measurements are the key to finding a perfectly fitting dress shirt.

  1. Neck: Use a cloth measuring tape to measure around the base of your neck, where the collar usually sits. Add half an inch to this measurement for comfort.

  2. Chest: Measure around the fullest part of your chest, keeping the tape parallel to the floor.

  3. Waist: Measure around the narrowest part of your waist, usually just above the navel.

  4. Arm Length: With your arm at your side, measure from the center back of your neck, over the top of your shoulder, and down to your wrist.

By following this step-by-step guide to measuring men's dress shirt sizes, you'll be well on your way to finding the perfect fit.

Factors to Consider When Determining the Right Size

While measurements play a significant role in determining the right size for men's dress shirts, other factors come into play as well. These include your body shape, personal style, and comfort level.

Common Size Charts for Men's Dress Shirts Explained

Now that you have your measurements and know what to look for, it's time to consult a men's dress shirt size chart. Size charts offer a reference point for comparing your measurements and finding the corresponding size.

Most brands, like DULO, have specific size charts that consider their unique fit and style. However, do note that sizing variations among different brands can occur. A medium in one brand might feel like a large in another. Therefore, always refer to the specific size chart of the brand you're shopping from.

Tips for Finding the Perfect Fit in Men's Dress Shirts

  1. Collar: A properly fitted collar should allow for two fingers to slip in comfortably when buttoned up. Anything looser or tighter might lead to discomfort.

  2. Sleeves: The cuff should end right at the base of your thumb, and there should be minimal excess fabric when your arms are down.

  3. Shoulders: The shirt's shoulder seams should perfectly align with your own shoulders' edges.

  4. Chest and Waist: The shirt should button comfortably without any straining at the buttons. It should provide enough room for movement, but not be baggy.

  5. Length: A good dress shirt should be long enough that it remains tucked in when you raise your arms.

In addition to these tips, consider the shirt's fabric. For instance, DULO's men's performance dress shirts use modern tech performance fabrics, providing flexibility and comfort, essential for the active man.

Consulting a Tailor for Accurate Sizing

Despite your best efforts, you might find that off-the-rack shirts don't quite fit the way you want. In such cases, consulting a tailor for accurate sizing can be a game-changer. A tailor can adjust a shirt to perfectly suit your body shape and size, delivering a custom fit that's hard to beat.


Understanding how men's dress shirts are sized can seem overwhelming at first, but with the right knowledge and a little practice, you can easily find your perfect fit. Take your measurements, consult the size chart, consider the fit and fabric, and you'll be well on your way to looking sharp and feeling comfortable in your dress shirt.
