ChatGPT Prompt for Poster Design: 12 Print Layouts

A ChatGPT prompt for poster design should lock your real headline, date, size, and brand colors before it suggests layouts. Use these prompts for wireframes, type hierarchy, hero image prompts without in-image text, and print checklists. Do not let the model invent sponsors or logos. Below are 12 copy-paste prompts plus a flagship layout prompt.

Set final type in a design tool. Image models often garble letters, so keep typography out of the generated art.
