How To Measure Collar Size

How do I accurately measure my collar size at home?

To accurately measure your collar size at home, use a flexible measuring tape to measure around your neck where your collar would sit, keeping the tape comfortably loose. Add ½ inch to this measurement to allow for comfortable movement and breathing room. This final number is your accurate collar size.

For the most precise measurement, avoid using old or stretched-out measuring tapes, as they may give inaccurate readings. Stand in front of a mirror to ensure the tape is level around your neck, not tilted up or down. The tape should rest comfortably against your skin, but you should be able to easily slip a finger between the tape and your neck. This extra space is crucial for comfort and ensures that your shirt collar isn't too tight. Remember that collar sizes can vary slightly between different shirt brands. It's always a good idea to check the specific sizing chart for the brand you're purchasing from, especially if you're ordering online. Knowing your accurate collar size is the first step toward achieving a perfect and comfortable fit.

What's the best way to measure collar size for a perfect fit?

The best way to measure your collar size is by using a flexible measuring tape to measure around your neck where your collar would typically sit. Ensure the tape is snug but not tight, allowing enough room to comfortably fit one or two fingers between the tape and your neck. This measurement, in inches, is your collar size.

For a more accurate measurement, it's best to wear a dress shirt that fits you well. Button the shirt all the way up and then measure from the center of the button to the center of the buttonhole on the opposite side. This method accounts for the shirt's actual collar length when closed, ensuring a comfortable and true-to-size fit. Avoid measuring your neck without a shirt or measuring too loosely, as these approaches can lead to an inaccurate measurement and an ill-fitting collar. Remember to round up to the nearest half-inch if your measurement falls in between whole numbers or half sizes, ensuring you have enough room for comfortable movement. Also, consider the fabric of the shirt. Some fabrics shrink after washing. If you are buying a shirt made of a fabric known to shrink (like some cottons), you might want to add a quarter or half inch to your measurement to compensate for potential shrinkage after the first wash. This will help ensure that the collar remains comfortable even after the shirt has been laundered.

What if I don't have a flexible measuring tape to measure collar size?

If you don't have a flexible measuring tape, you can use a non-stretchy string, ribbon, or even a piece of paper. Wrap it around your neck where your collar would sit, mark the point where the ends meet, and then measure the length of the string or paper with a ruler or a standard measuring tape. Remember to add a bit of extra space (about half an inch to a full inch) for comfort and movement.

To elaborate, the goal is to replicate the process a flexible measuring tape provides. The string or paper acts as a temporary, non-flexible measuring tool. Ensuring you mark the exact point where the string or paper meets is crucial for an accurate measurement. Using a pen or fine-tipped marker can help with precision. After marking, lay the string or paper flat on a table and use a ruler or yardstick to determine the length from the starting point to the marked point. Most standard rulers have both inches and centimeters, providing flexibility in your measurement units. Finally, it's important to remember the comfort allowance. A collar that fits too tightly can be uncomfortable and restrict breathing. Adding that extra half-inch to a full inch allows for comfortable movement and buttoning of the shirt. This also prevents the collar from feeling restrictive when you move your head or wear a tie. If you're between sizes, it's generally best to err on the side of a slightly larger collar size, as it's easier to adjust a slightly loose collar with a tie or by adjusting the top button than to deal with a collar that's too tight.

How does collar size differ between men's and women's shirts?

Collar size is primarily a measurement associated with men's shirts, reflecting the circumference of the neck in inches, while women's shirts typically don't use a direct collar size measurement. Women's shirt sizes are generally based on overall body measurements like bust, waist, and hip, which indirectly influence the neck opening but don't quantify it as a specific collar size.

While some women's blouses might have a collar, they are usually designed with more flexibility and often incorporate features like adjustable closures, stretchy fabrics, or looser fits. This is because women's necklines are more diverse and often styled differently than men's collared shirts. Therefore, manufacturers prioritize overall fit and styling over providing a precise neck circumference measurement. Instead of a number representing neck circumference, women's shirts are usually categorized by standard sizes like XS, S, M, L, XL, etc. These sizes correlate to a range of body measurements, and the neck opening is designed to proportionally fit within that size category. When purchasing a women's blouse with a collar online, it’s always a good idea to check the detailed size chart provided by the brand to understand the specific neck opening measurement associated with each size. This helps ensure a comfortable and flattering fit.

Does neck size always equal collar size?

No, neck size doesn't always perfectly equal collar size. While your neck measurement serves as a good starting point, collar size typically includes some added ease for comfort and movement. You usually need to add a little extra to your neck measurement, typically around half an inch to a full inch, to determine your ideal collar size.

Finding the right collar size is essential for comfort, especially when wearing dress shirts. A collar that's too tight can restrict breathing and movement, while one that's too loose can look sloppy and unprofessional. The standard practice of adding that extra allowance accounts for natural variations in neck size throughout the day, as well as the thickness of the fabric and the inclusion of a tie, if desired. It's always better to have a little breathing room than to feel constricted. Here's a simple method to measure for optimal collar size:
  1. Use a flexible measuring tape.
  2. Wrap the tape around your neck where a shirt collar would normally sit.
  3. Keep the tape snug but not tight. Ensure you can slip one or two fingers comfortably between the tape and your neck.
  4. Round up to the nearest half inch. This is typically your ideal collar size.
