How to find your right Shirt Size (Complete Guide)

A very simple guide, about men's shirt size, decoded.

A shirt is always measured by a collar length.
A collar is the pivot point for a men's shirt.
If you see size 40 in a shirt, this means the length of the collar is 40 cm.
Similarly, size 42 means, the length of the collar is 42 cm.

Collar length is universal. Other measurements like chest, waist, sleeves, the shoulder can be different for different countries or manufactures.

A size 40 shirt from one brand may have 42 inches chest length, and for another brand, it may have 44 inches chest length.

A size 40 shirt in Slim fit may have 42 inches chest length, and for Regular fit, it may have 46 inches chest length within the same brand.

In the physical store, it's easy to put on trial for the right fit shirt.
However, for online purchase, it is very important to go through the shirt size chart.

Now you know, shirt size, let's move on to find your match.

One must know his body measurement.
