Print size from resolution
Print size is simply pixel dimensions divided by the print resolution (dots per inch, or DPI): width in inches = pixel width ÷ DPI, and the same for height. Higher DPI packs more detail into a smaller physical print; lower DPI stretches the same pixels across a larger area.
300 DPI is the standard target for sharp, close-viewing prints like photo prints and magazines. Large-format prints viewed from a distance — posters and banners — can use much lower DPI (100–150 or less) because viewers stand farther away and won't notice the lower pixel density.
Example: a 6000 × 4000 pixel photo (24 megapixels) printed at 300 DPI yields a 20 × 13.3 inch print (about 50.8 × 33.9 cm) — a common size for large fine-art prints.
Common questions
What DPI should I use for photo prints?
300 DPI is the standard for sharp results viewed up close. You can go as low as 150–200 DPI for larger prints or ones viewed from farther away without a visible quality loss.
Can I print larger than the calculated size?
Yes, but the effective DPI will drop, which can make fine detail look soft — especially up close. Large posters and banners tolerate lower DPI because they're viewed from a distance.
