AI Poster Maker
Event, film and typographic posters that hold up printed at A2.
A poster is read from across a room and then from arm’s length. This AI poster generator composes for both distances: one image or typographic idea that carries at ten metres, and a detail block that rewards stepping closer. Start from a written prompt or attach a photo to build the poster around — either way the file downloads with no watermark on it.

Why use this instead of a template
Reads from a distance
One dominant idea and a title with real weight — the thing that decides whether a poster works on a wall at all.
Serious typography
Display type set on a grid with a proper credit block, not a headline dropped over a stock photo.
Print-aware layout
Margins and safe areas that survive a trim, so nothing important is guillotined at the edge.
Style on request
Swiss, art deco, risograph, cinematic — naming a school gets you a poster with a point of view.

Standard poster sizes and print ratios
The A series shares a ratio close to 1:1.414, while the common US sizes are a clean 3:4 and 2:3. Generating at 2:3 or 3:4 keeps a design compatible with the widest set of printers and frames — these are the sizes worth designing to:
- A2 — 420 × 594 mm (16.5 × 23.4 in)
- The usual gig and exhibition poster. Big enough to read across a room, small enough to fly-post and to frame cheaply.
- A3 — 297 × 420 mm (11.7 × 16.5 in)
- Noticeboards, café windows and shop counters. The size most office printers will handle without a print shop.
- A1 — 594 × 841 mm (23.4 × 33.1 in)
- Hoardings and large-format display. Generate at 3× if you are going this big.
- 18 × 24 in — a clean 3:4
- The standard US small poster, and the size most US framing is built around.
- 24 × 36 in — a clean 2:3
- The US film-poster size. Also the ratio to pick if one design has to work in both print and a phone screen.
Whatever the size, keep type at least 10 mm inside the trim edge. Print shops cut with a tolerance, and a title that touches the boundary in the file often loses a few millimetres on the wall.
The two-distance rule
Good poster design serves two viewers. The one walking past needs a single image and a title, resolved in under a second. The one who stopped wants the date, the venue, the line-up and the small print.
Those are different type sizes with a big gap between them. Posters that fail usually set everything at a middle size, which serves neither viewer.
Poster styles you can name in a prompt
Poster design has deep traditions, and naming one is the single most effective thing you can put in a prompt. A named style decides the grid, the palette and the type all at once, which is far more coherent than asking for something simply modern:
- Swiss international
- A hard grid, a strict palette and Helvetica-like discipline. The default for anything that needs to look serious.
- Risograph
- Misregistered spot colour, visible grain and a two-ink palette. Reads handmade without looking amateur.
- Retro travel
- Flat colour, stylised landscape and a confident single headline. Good for festivals and anything place-led.
- Bauhaus / constructivist
- Primary colours, hard diagonals and geometric blocks. Loud at a distance, which is exactly a poster’s job.
- Cinematic key art
- A photographic hero image, a credit block at the foot and a title treatment that carries the mood.
- Punk / xerox
- High-contrast photocopy texture, cut-and-paste type and deliberate roughness. Built for gig posters.
Pick the tradition that suits the event and let it make the small decisions for you. If the first board is close but too busy, the most productive refinement is almost always subtraction.
Poster Maker FAQ
Describe the event in one line — what it is, the mood, the style, and the exact text you want set. Generate at 2:3 or 3:4, ask in chat for a bigger title or a quieter palette, then export at 2× or 3× for print.
Use 2:3 or 3:4 — these map cleanly onto A3, A2, 18 × 24 in and 24 × 36 in, so one design covers most print and framing options.
Yes. Attach a photo as a reference and the poster is composed around it — the image is cropped and colour-graded to fit, and the title and detail block are placed clear of the busy parts rather than dropped on top.
No. Nothing is stamped on your export, including on the free plan, so a poster can go straight to a print shop.
No install. It runs in the browser on desktop and phone, so you can write the prompt, refine the design and download the file from wherever you are.
It will generate a poster-shaped image, but usually with garbled type, no control over the trim size and nothing you can revise except by starting again. Here the text you write in quotes is set as typed, the output is generated at print ratios, and you refine the same design in chat instead of rerolling it.
They are generated at high resolution with margins that survive a trim. For professional printing, confirm your printer’s bleed and colour requirements and export at the size they ask for.
Yes. Include the exact text in your prompt and it is set into the detail block. Proofread the result before printing a run.
Naming a style — Swiss, art deco, risograph, cinematic key art — is the most effective instruction you can give, and shifts palette, type and composition together.
Yes, with free credits and no card required. Each generation costs 2 credits; refinements and exports are unlimited.
