Paper size and pixels
How it works
Pixels = inches × DPI. A4 at 300 DPI is 8.27 × 300 = 2480 pixels wide.
300 DPI is print quality for documents and photos viewed up close; large posters and banners are often fine at 150 DPI or less.

Extra image beyond the trim line, usually 1/8 in (3 mm) per side, so nothing white shows after cutting.
