Pixel dimensions by resolution
Pixels are not a property of the paper — they depend on the resolution you print at. Build the document at the size you will actually output.
| Resolution | Pixels (W × H) | Use for |
|---|---|---|
| 72 DPI | 323 × 459 | Screen and web only |
| 96 DPI | 431 × 612 | Windows screen default |
| 150 DPI | 673 × 957 | Draft and home printing |
| 300 DPI | 1,346 × 1,913 | Standard for commercial print and print-on-demand |
| 600 DPI | 2,693 × 3,827 | Fine art and high-detail line work |
300 DPI is the number you want in almost every case. Print-on-demand services, Etsy printables and commercial printers all expect it. Exporting at 72 DPI and enlarging does not add detail — it just prints the same pixels bigger and softer.
