The Collar Size Calculator is a handy tool designed to help you calculate the ideal collar size for your shirts. Collar size is essential for a comfortable and well-fitting shirt, especially for formal occasions. By inputting your neck measurement and shirt size, this tool provides the most accurate collar size for you.

Formula

The collar size is calculated using the following formula:

Collar Size (C) = Neck Measurement (N) + (Shirt Size (S) ÷ 2)

Where:

  • Neck Measurement (N) = The circumference of your neck.
  • Shirt Size (S) = The shirt size you typically wear.

How to Use

  1. Enter your Neck Measurement (N) in inches or centimeters (depending on your measurement system).
  2. Input your usual Shirt Size (S).
  3. Click on the Calculate button.
  4. The tool will display your ideal Collar Size (C).

Example

If:

  • Neck Measurement (N) = 15 inches
  • Shirt Size (S) = 16

Then, the formula would be:
Collar Size (C) = 15 + (16 ÷ 2)
Collar Size (C) = 15 + 8 = 23 inches
