| 600 DPI | 2480 x 3496 pixels |
Printers work in dots per inch, not pixels, so a file sized for the screen is rarely ready for paper. Preparing the image at 1240 x 1748 pixels means the printer has a real 300 DPI of detail across the full A6 sheet rather than upscaling a smaller file and producing soft edges.
At 300 DPI A6 is 1240 x 1748 pixels. At 150 DPI it is 620 x 874, and at 72 DPI it is 298 x 420.
300 DPI is the standard for photo and document printing. 150 DPI is acceptable for large posters viewed from a distance, and 72 DPI is screen only.
