Frequently Asked Questions
Can I print an 8x10 inch photo with a 12MP camera?
Yes! A 12MP photo (4032 x 3024 px) yields approximately 378 DPI on an 8x10 inch print, which exceeds the 300 DPI lab standard for razor-sharp quality.
What is the minimum DPI for acceptable photo printing?
For handheld prints, 240–300 DPI is optimal, while 150–200 DPI produces acceptable quality for casual snapshots. Anything below 150 DPI will show visible softness or pixelation up close.
