Tips: Make AI Posters Sharp and Ready to Print

Almost all the AI poster makers impose resolution restrictions, with certain platforms restricting users to 1080p resolution unless they opt for their pro plans, while others fail to accommodate 4K and higher resolutions even for premium accounts. Unfortunately, low resolution posters cannot be used for 300DPI high quality printing at larger inches.

Print Size = Resolution/DPI. For instance:

• 12x18 inch=(3600 x 5400)/300
• 16x20 inch=(4800 x 6000)/300

For posters, you need higher resolutions for large size printing. For larger posters, 150DPI is also ok because you are viewing in a distance.

• Small posters - 11x17 inches - 3300x5100
• Medium posters - 18x24 inches - 5400x7200
• Large posters - 24x36 inches - 7200x10800 (150DPI - 3600x5400)
• Movie posters - 27x40 inches - 8100x12000 (150DPI - 4050x6000)
