T-Shirt Size Charts
Just because two shirts both say “Adult Large” doesn’t mean they are the same size. This page demonstrates the differences between our most popular t-shirt styles: Gildan® 100% Cotton T-shirts and Gildan® 50/50 T-shirts.
The sizes posted above are averages, not absolutes. All manufactured garments will vary slightly in size, sometimes as much as 1/2 inch in any direction.
How these charts work
These charts tell the measurement of the shirt as it lays flat on a table not measurements on a person. “Width” is measured from below where the sleeves connect to the body of the t-shirt and “Length” is measured from the bottom hem to the top of the collar.
