A poster is a layout problem before it is an image problem: a headline zone, a hero, a details block, and margins that hold it together. Most AI poster generators ignore that and produce a beautiful picture with nowhere to put the words, which is why the result ends up unusable.
This one is composed for text. Choose an event, sale, concert, birthday, festival or quote poster, pick a mood, and the prompt asks for a hero subject plus deliberate empty space at the top for a headline and at the bottom for details, in a 3:4 print ratio.
Poster types and the layout each one needs
| Type | Hero | Where the text goes |
|---|---|---|
| Event | Central subject or venue | Headline top, details block bottom |
| Sale | Product or price callout area | Big number in the top third |
| Concert | Artist silhouette or stage light | Large title centre, date at the base |
| Birthday | Portrait in a frame | Name above, date and venue below |
| Festival | Diyas, marigold, warm light | Greeting top, brand line bottom |
| Quote | Minimal texture or gradient | One line centred, attribution below |
Generate the background first, then set the type in a design tool. Text drawn by an image model is unreliable beyond two or three words.
How to generate a poster in three steps
- 1Decide the type and the moodType determines the layout, mood determines the palette. Bold for retail, elegant for weddings and premium launches, fresh for SaaS and lifestyle, dark for music and film.
- 2Upload a photo only if you have oneA product shot, a portrait or a logo. Without an upload the model designs from the brief alone, which is often better for a background plate.
- 3Describe the content, not the designSay what the poster is for and what text it must carry, then let the model decide the composition. Describing the design ("a red gradient with bold type") usually produces a worse layout.
Why the type belongs in a design tool
Image models draw letters as shapes. At two words they often get away with it; at a date, a venue and a price, they produce near-misses that look wrong at a glance and are impossible to edit. A poster with a misspelled venue is worse than a poster with no type at all.
The workflow that avoids this: generate a 3:4 background with clean zones, then place text in Canva, Figma or any editor, at the exact size the print needs. You get AI composition with real typography, and the file stays editable for the next event.
Print or screen: sizes that matter
- A4 print: 2480 × 3508 px at 300 DPI. Generate at 1344 px, then upscale free on this site.
- Instagram portrait: 1080 × 1350, the 4:5 ratio.
- Story or WhatsApp status: 1080 × 1920, so re-generate in a taller ratio.
- A3 print: double A4; upscale to 3508 px on the short edge before printing.
- Always keep a 5 mm margin free of critical content so a print shop trim does not cut the headline.
Free poster generator vs a template library
Templates give you proven layouts and editable type in a minute, and for a standard sale or a birthday they are the faster answer. What they cannot do is make an image that belongs to your brand: the hero, the light and the palette are all borrowed.
Generation is the other half. Use it when the visual is the differentiator, then combine: generate the hero, bring it into a template, replace the stock photo. That hybrid is what most small studios actually do.
Credits, formats and privacy
Each poster costs credits, priced per model and shown before you run, and new accounts start with free credits. Output is 3:4 at up to 1344 pixels with no watermark, and an optional photo or logo upload is capped at 4 MB.
Images are sent only for the request and results are stored only so you can download them, with no public gallery. For a print-ready file, upscale after generating.
Composition rules that make a poster read from across a room
A poster is read in a fraction of a second, from a distance, usually while the viewer is moving. That means one focal point, high contrast, and type large enough to read at three metres. Everything else is decoration, and decoration is what makes an amateur poster look busy and a professional one look calm.
The practical rule is the squint test: blur your eyes and look at the poster. If you can still tell what it is for, the composition works. If it turns into an even field of colour, there is no focal point and no amount of typography will fix it.
- One hero, one message. Two subjects halve the impact of both.
- Leave real empty space: crowded edges are what make a generated poster look cheap.
- Keep the headline zone at the top or centre, never in a corner.
- Contrast the text against the background at the design stage, not afterwards.
File formats the printer will ask for
Most Indian print shops accept a JPEG at 300 DPI at final size, and that is what this workflow produces after upscaling. If they ask for a PDF, place the image in a document at the exact trim size rather than exporting a JPEG as PDF, because a JPEG converted at the wrong resolution arrives either soft or enormous.
Ask two questions before you pay: what resolution do you want on the short edge, and do you want RGB or CMYK. The answers decide whether the file needs a second export, and they take one message to find out.
Colour and ink: why gold looks cheap in print
Gold rendered on a screen is a warm yellow with a gradient; gold printed in CMYK is a brownish ochre that reads as beige under office light. If the poster depends on a metallic feel, the honest route is a foil or a metallic stock, which no digital file can promise. For everything else, lean on contrast and scale instead of imitating a material.
