At each resolution
Pixels are the size in inches times the dots per inch, after dividing millimeters by 25.4. 300 dpi is right for anything seen at arm's length; a poster seen from across a room can be 150. 72 dpi is only for showing on a screen.
| Resolution | Pixels | Megapixels |
|---|---|---|
| 72 dpi | 842 × 1191 | 1.0 MP |
| 150 dpi | 1754 × 2480 | 4.3 MP |
| 300 dpi | 3508 × 4961 | 17.4 MP |
| 600 dpi | 7016 × 9921 | 69.6 MP |
With bleed
If the art runs to the edge, the printer wants it to run past the edge too, so a sliver of white never shows where the paper's cut. That's bleed: 3 mm on each side is usual for ISO paper. A3 with bleed is 303 × 426 mm, or 3579 × 5031 pixels at 300 dpi. Keep words and faces at least as far inside the edge again. Your printer's spec sheet has the last word.
