Frequently Asked Questions
How many megapixels do I need for an 8x10 print?
An 8x10 inch print at 300 DPI requires 2400 x 3000 pixels, which is approximately 7.2 megapixels.
Can I print larger than the 300 DPI recommendation?
Yes. Larger prints (such as 20x30 inch wall posters) are viewed from several feet away, where 150 DPI provides sharp visual quality.
