Plus, we’ll provide you with a collar size chart to guide you in choosing the right fit for your shirts.


What Is Collar Size, and Why Is It Important?

Your collar size refers to the circumference of your neck, and it’s used to determine how large the collar of a shirt or jacket should be.

A properly fitted collar ensures that your shirt is comfortable, fits well, and doesn’t feel tight or loose around your neck.

Typically, collar sizes are measured in inches or centimeters. For men’s shirts, the collar size is the measurement around your neck just above the collarbones.

For women, it’s generally measured similarly, but the collar might be sized differently based on the style or fit of the shirt.

Now that we know what collar size is, let’s talk about how to measure collar size for shirt and how our collar size calculator can make this process easier.


How to Measure Your Collar Size?

If you’re wondering how to measure your collar size, it’s a relatively simple process. Follow these steps to get an accurate measurement:

  • Get a Soft Measuring Tape: A flexible measuring tape is the best tool for this job.
Neck Circumference
  • Measure Around Your Neck: Place the measuring tape around your neck, just below your Adam’s apple, where the collar of your shirt will sit.
  • Add Extra Room: When you measure, make sure you don’t pull the tape too tightly. You should be able to fit one finger between the tape and your neck to ensure comfort.
  • Record the Measurement: Note the number where the tape meets. This is your neck measurement.

For example, if the measurement around your neck is 16 inches (40.64 cm), that would be your collar size.

If you’re using our collar size calculator, simply input your neck circumference and sleeve length into the tool, and the calculator will provide you with a recommended collar size based on the required inputs.

You’ll receive your collar size in both inches and centimeters, making it easy to shop for shirts and jackets that fit perfectly.


How to Use Our Collar Size Calculator?

Our collar size calculator is a handy tool designed to help you calculate your collar size based on two key measurements: neck circumference and sleeve length.

Steps to Use the Calculator:

  • Select the Unit: Choose whether you want to display the result in inches or centimeters.
  • Enter Your Neck Circumference: Measure your neck using the instructions above and input the value into the calculator.
  • Enter Your Sleeve Length: Measure the length of your sleeve (from your shoulder to your wrist) and input that value as well.
  • Calculate: Press the “Calculate” button, and the tool will give you your collar size based on the formula given below.

C = N + (S / 2)

Where C is the collar size, N is the neck circumference and S is the sleeve length.

The result will show your estimated collar size in both inches and centimeters, so you can choose the best option for you.
