QR Codes on Posters
A poster gets attention, and a QR code turns that attention into action. Because posters are often read from a distance, the code needs to be sized for that gap so people can scan it comfortably without stepping right up to the wall.
How to use it
Set a clear goal
Decide what the scan should do, such as book a ticket, order online or follow your page.
Create the QR code
Generate a high-contrast URL code and download the SVG for large-format printing.
Size by viewing distance
Use at least one-tenth of the reading distance, so a poster read from 2 metres gets a code around 20 cm.
Place and test on site
Position the code at a comfortable height and scan it from the real standing spot before printing.
Tips for best results
Give it a quiet zone
Large posters still need clear space around the code, so keep the surrounding area uncluttered.
Place at a walk-by height
Put the code at eye level in the flow of foot traffic so scanning feels natural.
Add a bold instruction
A short line such as "Scan to buy tickets" removes any hesitation.
Keep the link fast-loading
Large crowds on mobile data need a light landing page, so test the speed before the campaign.
Best practices
Scale the code, avoid stretching
Enlarge the QR code proportionally so it stays square. Stretching distorts the modules and breaks scanning.
Strong contrast
Dark code on a light panel is safest on a large poster, especially outdoors.
Avoid glossy large-format
Gloss creates glare on big prints, so specify a matte or satin finish over the code.
Test from the real distance
Scan the proof from where people will actually stand, in the actual lighting conditions.
Design examples
Event poster
A large code that adds the event to your calendar or opens the ticket page.
Retail poster
A code linking to a sale page or an online store.
Recruitment poster
A code that opens the job listing and application form.
Frequently asked questions
Use at least one-tenth of the scanning distance. A poster read from 2 metres needs a code of roughly 20 cm, and larger is safer outdoors or in busy spaces.
They can, if they are large enough and high-contrast. The trick is sizing the code to the distance, so enlarge it whenever the poster will be read from a few steps back.
Yes, with a few precautions: keep contrast high, avoid glossy finishes that glare in sunlight, and test the code under bright light before printing.
Link to the immediate action the poster is asking for — tickets, an order page, a sign-up or your social profile. Avoid dumping people on a generic homepage.
Yes. Add UTM parameters to a URL code so you can see exactly how many visits came from that poster in your analytics.
