How to Make a QR Code for a Poster or Flyer (Free, 2026)
A poster gets glanced at from a distance, so a QR code on it has to be big enough and clear enough to scan without anyone stepping right up to it. Get the size, format, and placement right and you turn passers-by into visitors, sign-ups, or ticket buyers. This guide gives you the free steps plus the print rules that keep your code scannable.
Quick answer
To make a QR code for a poster, paste your destination link into a free QR code generator like onesol.io/qr-code-generator and download it as an SVG or PDF so it stays sharp when enlarged. Size it using the 10-to-1 rule — the code should be about one-tenth of the scanning distance, so roughly 4 inches (10 cm) wide for a poster people scan from a meter away — and add a short "Scan me" prompt.
1. Pick one clear destination
A poster works best with a single, obvious action, so choose one link: buy tickets, RSVP, view the menu, or follow you. If you want the code to cover several things, point it at a link-in-bio page (like one at onesol.io) that lists them, rather than cramming multiple codes onto the design.
2. Generate a vector, print-ready code
Paste your link into a free tool such as onesol.io/qr-code-generator and download an SVG or PDF. Vector formats scale to any poster size without pixelation, which matters because a blurry enlarged PNG is a common reason poster codes fail to scan.
3. Size it for the scanning distance
Use the 10-to-1 rule: the printed code's width should be about one-tenth of how far away people scan from. For a poster read at roughly one meter, make the code around 4 inches (10 cm) wide, and keep the empty quiet-zone margin and strong dark-on-light contrast intact.
4. Place it well, then test a printed proof
Put the code at a comfortable eye-to-chest height, not near the floor or a corner someone can't reach, and away from busy background art. Print a full-size proof and scan it from the real viewing distance on more than one phone before you print the full run.

FAQ
How big should a QR code be on a poster?
Follow the 10-to-1 rule — the code's width should be about a tenth of the scanning distance. For a poster scanned from a meter away, that's roughly 4 inches (10 cm); print larger for banners viewed from further back.
What file format is best for printing a QR code?
An SVG or PDF, because these are vector files that stay crisp at any size. If you must use a PNG, export it at 300 DPI or higher at the final printed dimensions.
Should I add text next to the QR code?
Yes — a short prompt like "Scan for tickets" or "Scan me" noticeably increases scans by telling people what they'll get. Keep it right beside the code.
Can I use one QR code for several links on a flyer?
Point a single code at a link-in-bio page (like one at onesol.io) that lists all your links, instead of printing multiple codes. It keeps the design clean and lets you update the links later without reprinting.
