What size PNG do I need for a t-shirt print?
Print width in inches is the pixel width divided by the print resolution. A 2048 pixel file is about 6.8 inches at 300 pixels per inch and about 13.6 inches at 150.
- Decide the print area. A left chest print is 3 to 4 inches wide. A full front is 10 to 12.
- Check your print service. Each one publishes the pixel size it recommends for each product.
- Compare with your file. Each preview here shows the file's pixel size.

What this tool gives you
Files stop at 2048 pixels on the long side, and an upload is never enlarged.
For a larger print area
Enlarge the file in an image editor first. Enlarging adds pixels, not detail, so bold shapes take it better than fine lines.
