Frequently asked questions
What is the largest I can print a photo?
Divide the pixel width by 300 DPI for a crisp print. A 4000 pixel wide photo prints sharply up to about 13 inches wide.
Can I print bigger than the calculator suggests?
Yes, but the print gets softer. Larger posters tolerate lower DPI, around 150, because viewers stand farther away. Check the exact tradeoff with the DPI calculator.
What print sizes do common resolutions support?
At 300 DPI, 1200 by 1800 pixels prints 4 by 6, 2400 by 3000 prints 8 by 10, and 3000 by 2000 prints 10 by 6.67.
