Photo Print DPI Checker
Enter your image pixel dimensions to see the largest sharp print size before you order.
Quick answer: Divide image pixel width by 300 to get maximum sharp print width in inches at 300 DPI. Example: 2400 px width → 8 inch wide print.
This calculator estimates effective DPI when you stretch a digital file to a physical print size. 300 DPI is professional target; 200 DPI may work for small album prints viewed up close; below 150 DPI often looks soft on walls.
