AI movie poster generator
Describe your film — the genre, one image that sums it up, the palette, and a short title — and get back an original theatrical poster in the real 2:3 one-sheet shape. One dominant piece of key art, a value structure that still reads at thumbnail size, and a quieter lower third where the title sits.
Movie poster examples
How it works
A poster sells one idea. Give the genre, the single image that carries it, two or three colors, and a short title if you want one on the artwork. Attach a photo to build the key art from.
YouArt returns one 1K poster in the 2:3 theatrical shape for 8 credits, with the key art composed and the lower third left quieter for the title.
Look at the poster at thumbnail size before you commit. A one-sheet that stops reading when it is small has too many competing values, which is a composition fix rather than a detail one.
What the generator controls
A theatrical one-sheet is 27 by 40 inches, near enough to 2:3, and this page generates in that ratio rather than cropping a square down to it. What you get is a poster's proportions, at print-ready 1K.
Horror wants one light in a lot of dark; a heist wants silhouettes and flat color; a drama wants a face and empty space. The treatment follows the genre you name instead of defaulting to one house style.
The composition reserves the bottom of the frame, where a real poster carries its title and credit block, so there is somewhere to put type — whether the generator draws it or you add your own later.
Prompt ideas
Name the genre, the one image that carries the film, and two or three colors. A short title renders; a tagline, a release date and a cast list do not — keep those for the layout you build afterwards.
A folk-horror one-sheet: a small stone church alone on a moor under a bruised violet sky, one lit window, everything else in silhouette, muted green and violet.
A science-fiction poster of a lone figure on an orange dune beneath an enormous ringed planet, burnt orange and cold grey, title THE LONG QUIET across the bottom.
A heist poster: five figures in a row in hard backlight, reduced to black silhouettes against a deep red ground, chrome highlights only, nothing else in the frame.
Ways to use it
Give a short a poster it can be submitted and shared with, without a design budget or a photoshoot you cannot afford to stage.
A one-sheet says what a synopsis takes a page to say. Try three genres' worth of key art for the same idea and see which one the room reacts to.
Make a poster for a tabletop campaign, a film club night, or the imaginary blockbuster your group chat has been casting for a week.
The 2:3 ratio is a standard print size, so an original poster goes to a printer and into a frame without being cropped to fit.
This generator uses 8 credits for one 1K image. Membership credits work across YouArt image, video, audio, and workflow tools.
