From Screen to Billboard: Mastering AI Resolution

Creating stunning AI imagery in Midjourney is only half the battle. The raw output is typically around 1024x1024 pixels—perfect for Instagram, but disastrous for a physical magazine cover or a billboard.

DPI (Dots Per Inch) is the measure of spatial printing dot density. Standard web screens are 72 PPI. Professional print is 300 DPI. To print an A4 image full page, you need approx 2480 x 3508 pixels. Midjourney gives you less than a third of that.
2. AI Upscaling vs. Stretching
Old school upscaling (Bicubic) just made pixels bigger and blurrier. AI Upscaling (like Magnific or Topaz) understands the content. It knows what skin texture looks like and "hallucinates" new pores and details that weren't in the original low-res file.
Pro Tip: Never upscale text generated by AI. It becomes garbled. Always overlay typography in Illustrator *after* upscaling the background.
