Design a flyer or poster for print

A flyer and a poster are the same job at two sizes: one bold message, a clean layout, and a file that prints without surprises. This guide walks the whole path — from a print size preset to a finished PDF — and the recipe scales straight from an A5 handbill to an A3 wall poster without changing a step.

Choose a print size preset#

Start from New (in the File menu) and open the Print preset category. You'll find the sizes flyers and posters actually use:

Every print preset is built at 300 dpi and sets the correct units for you — millimeters for the A-series, inches for the US sizes — so you don't have to convert anything by hand. Pick the size closest to what you're printing; the design keeps its default name Untitled until you save it. If you need a size that isn't listed, enter a custom width and height instead — the canvas size and units reference covers that.

Work in CMYK with bleed#

Two settings turn a screen document into a print document. Set both before you design and you'll avoid color shifts and white edges later.

1. Switch View → Color mode → CMYK (print). Presses print with ink, not light, and CMYK soft-proofs your colors on screen so what you see is close to what comes off the press. It also unlocks the print-only checks below.
2. Open File → Document setup… and add a 3 mm bleed. Bleed is the artwork that runs past the trim line so the cut never leaves a white sliver. Turn on View → Show bleed to see the red guide, then run any background or full-bleed photo all the way out to it.

Keep important content — headline, contact details, logo — a few millimeters inside the trim edge. Trimming has a small tolerance, and a safe margin means nothing critical gets clipped. There's more on this in bleed and safe margins.

Build the layout#

A flyer is read in seconds, so hierarchy does the heavy lifting. Lead with one clear headline, then let everything else support it.

• Press T, draw a text frame across the top, and type your headline. Make it big and confident — style the font, size and weight in the Properties panel on the right.
• Add supporting text the same way: a subhead, the key details (date, place, price, a call to action), and a line for contact or a website. Keep the number of type sizes small — a big headline, a medium subhead, and body text is usually enough.
• Structure the page with guides and a grid. Drag a guide off the ruler to line up columns and margins, and enable a grid from the View menu to keep spacing even.
• Add shapes for color blocks and accents. Give your brand colors real names in Swatches so they stay consistent across everything you make.

Prefer to start faster? Describe the flyer to the Assistant on the left — its size, what it's advertising, and the look you want — and it lays out a first draft on the canvas for you to refine. Because the document is already sized and in CMYK, whatever it builds is print-shaped from the start.

Add imagery at the right resolution#

A hero photo makes a poster, but only if it holds up in ink. Add an image with the quick-add image button, then use the Fill or Fit controls in the Properties panel to seat it in its frame — Fill covers the frame edge to edge, Fit shows the whole photo.

In a CMYK (print) document, the editor watches the effective resolution of every image — the real pixels-per-inch at the size you've placed it, not the size of the original file. Scale a photo up and its effective PPI drops. When it does, a badge appears on the image:

Aim to keep hero images at 300 PPI or higher at their final printed size. If a photo turns amber or red, either scale it down in the layout or swap in a larger source file. Image resolution for print goes deeper, and the image resolution reference explains exactly how the badge is calculated.

Big posters and blow-ups#

Here's the reassuring part about large formats: a huge poster does not need a huge file. Effective PPI is only half the story — viewing distance is the other half. A flyer is read at arm's length, so it wants a full 300 PPI. A poster on a wall is seen from across the room, a banner from across the street, and at that distance the eye can't resolve fine detail anyway.

That's why a large-format print can look perfectly crisp at a lower PPI than a flyer would tolerate. The 300 PPI target is the gold standard for close reading; the further away something is viewed, the more you can relax it. Don't panic if a big poster's hero image shows an amber badge — step back mentally to the real viewing distance and judge whether the detail will actually be visible. When in doubt, the resolution guides above show how to weigh it.

Export a print PDF#

When the layout is done, produce the file your printer wants.

1. Use the Share split-button (or the File menu) and choose Download to open the Export dialog. Everything below runs in your browser — nothing is uploaded to a server.
2. Pick PDF and set the color space to Print (CMYK).
3. Turn on Bleed (3 mm) and Crop & registration marks so the printer can align the plates and trim to the right size.
4. Choose the PDF/X-4 standard and an Output profile that matches your print service — ask them which one, and pick it here so colors are converted correctly.
5. Leave Outline text on unless your printer specifically asks for editable text. Outlined text can't reflow or substitute a missing font on their end.

Before the file is written, the print checks flag anything risky — images under 300 PPI, heavy ink coverage, and other issues — so you catch problems here instead of on the proof. Export a print-ready PDF covers each option in detail.

That's a flyer or poster that looks the way you intended and prints the way your printer expects — one message, a clean grid, sharp imagery, and a PDF/X-4 with bleed and marks. When you're ready to go deeper, read export a print-ready PDF or brush up on image resolution for print.
