The best graphic size for print on demand tees (4200 x 4800)
A 4200 x 4800 pixel canvas gives a large front print enough detail to look sharp on cotton. Smaller files can look soft when stretched.
Export as PNG with a transparent background. A solid background prints as a visible box, which is the most common problem we catch.
Leave a little space around the artwork so nothing sits on the very edge of the canvas and gets cropped.
If your file is smaller, we can upscale it, but starting from the full size always looks best. Every DePOD graphic is checked by a real person and we tell you about any issue before we print.
