Collar Size Formula
The following formula is used to calculate the collar size for a given neck circumference and sleeve length.

C = N + (S / 2)

Variables:

• C is the collar size
• N is the neck circumference
• S is the sleeve length

To calculate the collar size, add the neck circumference to half of the sleeve length. This formula ensures a comfortable and well-fitting collar size.
What is a Collar Size?
Collar size refers to the measurement around the base of the neck, where the collar of a shirt would naturally sit. This measurement is crucial for ensuring a comfortable fit, especially for dress shirts and formal wear. A properly measured collar size ensures that the shirt fits well around the neck without being too tight or too loose. The collar size is typically measured in inches or centimeters and is an essential aspect of tailoring and clothing design.
How to Calculate Collar Size?
The following steps outline how to calculate the Collar Size.

1. First, measure the neck circumference (N).
2. Next, measure the sleeve length (S).
3. Next, calculate the collar size using the formula C = N + (S / 2).
4. Finally, calculate the Collar Size.
5. After inserting the values and calculating the result, check your answer with the calculator above.

Example Problem : 
Use the following variables as an example problem to test your knowledge.
Neck Circumference (N) = 40 cm
Sleeve Length (S) = 60 cm
