We want you to have the best purchase experience possible when it comes to the fit of your new shirt. So we spent hours scouring the internet and compiled this exhaustive shirt size sizing guide to help ensure you select the perfect size the first time and every time.

Already know your Size!

If you are confident you know your shirt size for your age/gender, lookup your size under the appropriate age/gender category and then look across the row to find the recommended product size highlighted in red. (This will correspond to the size on the product listing unless specifically noted.)

Don’t know your size?

To obtain the best fit for your shirt purchase, measure around the widest part of your chest/bust in inches to determine your circumference. Next find the corresponding value in the first column of the table below. (The gray column) Now look across the row to find the recommended product size highlighted in red. (This will correspond to the size on the product listing unless specifically noted.)

Helpful Notes:

S2GN Design Shop shirt size listings are typically in reference to the Toddler, Child/Youth, and Regular size categories highlighted in red on the S2GN Shirt Size Guide Table, unless noted otherwise in the product listing.

Please be aware we try to provide some general guidance in the product listing as to the fit of shirt brands/styles that may run a bit small or large. (“Classic fit” refers to a loose, but true to size fit.)

If your measurements end-up falling in between size categories it’s typically best to go with the next size up.
