How Do Dress Shirt Sizes Work?

When it comes to dress shirt sizes, finding the perfect fit can often be a challenge. Did you know that the sizing of dress shirts is not as straightforward as it may seem? The sizing system used for dress shirts involves a combination of neck circumference and sleeve length measurements, resulting in various sizes that cater to different body types. Understanding how dress shirt sizes work is essential for achieving a comfortable and stylish fit.

Historically, dress shirts were made in standardized sizes, which often posed a problem for individuals with unique body proportions. To address this issue, manufacturers began offering a range of sizes that consider both neck circumference and sleeve length. For example, a dress shirt size of 16-34 indicates a 16-inch neck circumference and 34-inch sleeve length. This system allows for a more customized fit and ensures that the shirt accommodates varying body shapes and sizes. By selecting the appropriate dress shirt size, individuals can enjoy both comfort and style, making a positive impression in any professional or formal setting.

Understanding Dress Shirt Sizes

When it comes to finding the perfect dress shirt, understanding how dress shirt sizes work is essential. From collar size to sleeve length, each measurement plays a significant role in ensuring a proper fit. Yet, many people find dress shirt sizing confusing and overwhelming. This article aims to demystify dress shirt sizes and provide you with a comprehensive guide to help you find the right fit.

Collar Size

The collar size is one of the most important measurements when it comes to dress shirts. It determines how comfortably the shirt will fit around your neck. To measure your collar size accurately, use a flexible measuring tape and wrap it around the base of your neck where the collar usually rests. Make sure to leave enough room for a finger to fit between the tape and your neck for a comfortable fit.

Dress shirts typically come in ½-inch increments, ranging from 14.5 to 19 inches for men. Some brands may also offer additional sizes such as 13.5 or 20 inches. It's important to note that collar size may differ between brands, so it's crucial to refer to the specific brand's sizing chart for accurate measurements. A shirt with a collar size too tight will feel constricting, while a loose-fitting collar may appear sloppy.

When purchasing a dress shirt, always aim for a collar size that allows you to comfortably button the top button without feeling any tightness or discomfort.

Converting Collar Size to Different Systems

If you come across dress shirts with collar sizes listed in centimeters or European sizes, you can easily convert them to the more common inch-based system. To convert centimeters to inches, divide the centimeter measurement by 2.54. For example, if a dress shirt is listed as 40 centimeters, dividing it by 2.54 gives you approximately 15.75 inches.

European collar sizes typically increase by 1cm increments. By converting them to inches, you can compare them to the inch-based collar sizes to find the suitable match.

Custom Collar Sizes

For individuals who have unique neck sizes that fall outside the standard range, custom-made dress shirts offer an excellent solution. With custom shirts, you can specify your exact collar size, ensuring the perfect fit. Many tailors and online retailers provide customization options to accommodate different body measurements.

Sleeve Length

The sleeve length is another crucial measurement to consider when determining your dress shirt size. To measure your sleeve length, stand up straight with your arm relaxed at your side. Start the measurement from the center of your back, where the spine meets the shoulder bone, and measure down to the point where you want the sleeve to end, usually around the base of the thumb.

Sleeve lengths typically come in two options: regular and long. Regular sleeve lengths are designed to accommodate individuals with arm lengths that fall within the average range, while long sizes cater to those with longer arm lengths. Some brands may also offer short or extra-long sizes for a more precise fit.

Choosing the right sleeve length ensures that the dress shirt does not appear too short or too long when worn. It also allows for comfortable movement without feeling constricted in the shoulders and arms.

Converting Sleeve Length

If you come across dress shirts with sleeve lengths listed in centimeters or European sizes, you can convert them to inches using the same method as converting collar sizes. Divide the centimeter measurement by 2.54 to obtain the approximate inch measurement.

Adjusting Sleeve Length

If you find that the dress shirt's sleeve length is slightly longer than desired, you can have it altered by a tailor. Shortening sleeves is a common alteration that can be done to achieve a more customized fit.

Shirt Size - Body Measurements

The overall fit of a dress shirt is determined by the body measurements, including chest circumference, waist circumference, and shirt length.

To accurately measure your chest circumference, wrap the measuring tape around the widest part of your chest under your armpits. Ensure that the tape is straight and not too tight or too loose.

The waist circumference is measured around the narrowest part of your waist, typically a few inches above the belly button.

Shirt length refers to the measurement from the bottom of the collar down to the hemline of the shirt. This measurement ensures that the shirt is long enough to be tucked in comfortably without constantly coming untucked.

Sizing Charts

Most dress shirt brands provide sizing charts that correlate body measurements to their shirt sizes. These charts can be helpful in determining the best size based on your specific measurements. Consult the brand's sizing chart to ensure the perfect fit.

Additional Considerations

When it comes to dress shirts, it's essential to consider individual preferences and styles. Some people prefer a more tailored and fitted look, while others opt for a looser and more relaxed fit. Understanding your preferred style can further guide you in finding the ideal dress shirt size.

It's also worth noting that different brands may have variations in their sizing. It's always a good idea to try on different brands and styles to find the one that suits you best.

Lastly, remember that dress shirt sizes are typically designed to accommodate a range of body types within a specific measurement range. Individuals with unique body proportions or sizes may need to explore custom-made options to achieve the perfect fit.

Finding the Perfect Dress Shirt Size

Knowing how dress shirt sizes work allows you to make informed decisions when shopping for dress shirts. By understanding your collar size, sleeve length, and body measurements, you can find the perfect fit that exudes both style and comfort. Remember to refer to sizing charts, try on different brands and styles, and consider your personal style preferences to ensure a dress shirt that fits flawlessly.

Frequently Asked Questions

Dress shirts come in various sizes to ensure a proper fit for every individual. Understanding dress shirt sizes can be crucial when shopping for the perfect shirt. Here are the answers to some frequently asked questions about dress shirt sizes.

1. What do the numbers and letters on dress shirts mean?

The numbers on dress shirts usually refer to the neck measurement of the shirt in inches. This measurement helps determine the collar size that will fit best. The letters typically represent the sleeve length of the shirt, such as S for short sleeves, R for regular sleeves, and L for long sleeves. It's important to note that different brands may have slight variations in their sizing standards. It's always recommended to refer to the specific brand's size chart for accurate measurements.

2. How do I measure my neck for a dress shirt?

To measure your neck for a dress shirt, you can use a measuring tape. Wrap the measuring tape around your neck, just below the Adam's apple, making sure to keep it comfortably snug. Round the measurement to the nearest half-inch or whole inch, as dress shirts are typically sized in whole numbers. You can also measure your neck by using a string and then measuring the length of the string with a ruler. Whichever method you choose, make sure to measure in a standing position and avoid pulling the tape or string too tightly.

3. How do I determine my dress shirt sleeve length?

To determine your dress shirt sleeve length, you will need to measure from the center back of your neck to your wrist. Start the measurement from the prominent bone at the base of your neck and then run the measuring tape over your shoulder and down to your wrist bone. Once you have the measurement, round it to the nearest whole inch. Generally, dress shirts come in standard sleeve lengths of 32/33 for short sleeves, 34/35 for regular sleeves, and 36/37 for long sleeves.

4. What if my measurements fall between two dress shirt sizes?

If your measurements fall between two dress shirt sizes, it's usually recommended to choose the larger size. It's easier to alter a dress shirt that is slightly larger than to try and make a smaller one fit properly. A larger shirt can always be tailored to fit your body measurements more precisely. Additionally, keep in mind that different brands may have slightly different fits and sizing guidelines, so it's advisable to try on shirts of different sizes and brands to determine the best fit for you.

5. Can dress shirts be altered to fit better?

Yes, dress shirts can be altered to achieve a better fit. Common alterations include taking in the sides to reduce the shirt's width, shortening the sleeves, or adjusting the collar size. It's best to consult with a professional tailor who can assess the shirt's fit on your body and suggest the necessary alterations to achieve an optimal fit. Keep in mind that alterations may incur additional costs, so it's essential to factor that into your budget when purchasing a dress shirt.


In summary, dress shirt sizes are determined using a combination of neck size and sleeve length measurements. The neck size is measured in inches, while the sleeve length is measured from the center of the back neckline to the end of the sleeve. These measurements are used to categorize dress shirts into different sizes, usually ranging from small to extra-large.

It's important to note that dress shirt sizes can vary slightly between brands, so it's always a good idea to refer to the brand's specific size chart when making a purchase. Additionally, it's helpful to know your own neck and sleeve measurements to ensure a proper fit. By understanding how dress shirt sizes work, you'll be able to find the perfect shirt that not only looks good but also feels comfortable.
