T-shirt design file requirements

Printers love vector files (AI, EPS, SVG or PDF). If you only have an image, send a PNG at 300 dpi at the actual print size with a transparent background.

Common print sizes

Placement Typical size
Full front 10-12 in wide
Left chest 3.5-4 in wide
Full back 12-14 in wide
Sleeve 3 in wide

So a full-front PNG should be about 3,000-3,600 pixels wide.

Color tips

  • For screen printing, count your colors: each is a screen.
  • Use solid colors instead of gradients to keep screen printing affordable.
  • Thin lines under about 1 pt may not print well.

Don’t use

Low-resolution logos from websites or social media, or images with white backgrounds you meant to be transparent.
