B3 in pixels
Pixel dimensions depend entirely on the resolution you are working at — there is no single "pixel size" for a sheet of paper.
| Resolution | Pixels | Use |
|---|---|---|
| 72 DPI | 1001 × 1417 | Screen preview only — far too coarse to print |
| 150 DPI | 2085 × 2953 | Draft printing, internal documents |
| 300 DPI | 4169 × 5906 | The standard for commercial print |
| 600 DPI | 8339 × 11811 | Fine detail, line art, archival scanning |
Setting up a print document? Use 300 DPI and add 3 mm of bleed on every edge unless your printer specifies otherwise.
