Frequently Asked Questions
What DPI do I need for photo printing?
300 DPI is the professional standard for photo prints. 150 DPI is acceptable for larger prints viewed from a distance. 600 DPI is used for fine art or gallery prints where extreme detail matters.
How many megapixels do I need for an 8x10 print?
At 300 DPI, an 8x10 print needs 2400x3000 pixels, which is 7.2 megapixels. Most modern smartphones (12+ MP) can easily produce 8x10 prints.
What happens if my image DPI is too low?
If your image has fewer pixels than needed, the print will appear blurry or pixelated. You can either print at a smaller size or accept lower quality.
