What file resolution do I need for large mounted prints?

Aim for 300 DPI at the final print size for sharp, detailed mounted prints.

• 300 DPI at full size is the standard for close-up viewing
• For very large formats over 36 inches viewed from a distance, 150 DPI can be acceptable
• Never upscale a small image to fake resolution. It turns soft and pixelated
• When unsure, submit the highest-resolution file you have and check the proof before printing
