AI Poster Maker
Bold, print-ready 2:3 poster art for events, promos and wall decor.
An AI poster maker generates striking, print-ready poster art from a single prompt - event posters, film-style key art, promo and motivational designs or wall decor. You get a tall 2:3 composition with space for a headline, ready to upscale and print. Describe the subject and mood, leave room for your text, and you have a poster without opening a design suite.
2:3 matches common print sizes (12x18, 24x36). Compose with space for a title and upscale before printing.

Frequently asked questions
What size should a poster be?
Common print sizes (12x18 and 24x36 inches) are a 2:3 ratio, which is the default here. Generate at 2:3, then upscale the result so it stays sharp at large print dimensions before sending it to print.
How do I add the poster text?
Generate the artwork with deliberate empty space for a headline, then add your real title, dates and details in a design tool. Keeping text out of the generation avoids garbled AI lettering and gives you full control over fonts.
Can I sell the posters?
Yes. Every image includes a commercial license, so you can sell prints, promote events and use the art in client work. Upscale before printing for crisp, gallery-quality output.
