Wall art sits between posters and photo books: often 150 DPI as a compromise, 240–300 DPI if viewers get close.
Recommended DPI for wall art
Start around 150 DPI, then adjust for size and viewing distance. Fine detail and text need higher DPI than soft photographic backgrounds.
Pixels still matter most
Pick the final print size first, multiply by target DPI, and check whether your file has enough pixels on the short side.
FAQ
What DPI do I need for wall art?
Often around 150 DPI, but large pieces viewed from farther away can use less.
