QR Codes on Event Posters and Flyers: Getting People to Scan

Picture a poster on a college noticeboard: a nice design, a code in the corner, and no mention of what happens when you scan it. Most people walk past. A QR code for flyers and posters works when someone has a reason to stop, can physically scan it from where they stand, and lands on something useful. All three matter, and only the last one happens on a screen.

Give a reason to scan

Nobody scans a code out of curiosity for long. Tell people what they’ll get, in a few words next to the code.

A specific benefit does the job. If the only thing you can say is “more information”, ask whether the poster could just say it. People also want to know it’s safe to scan, so make clear who’s behind it. Your event or brand name near the code helps.

Distance and size

A poster is read from further away than a flyer. You’ll see various rules of thumb that link code size to scanning distance. They differ between sources, so use them as a starting point and test at the real distance.

The test is simple. Print at real size, stick it up where it’ll go, stand where your audience will stand, and scan.

BioFlow’s dashboard gives you a 400-pixel PNG. That’s fine for a small flyer, but it may look soft on a large poster. If so, create a vector or higher-resolution code for the same address using a generator, and ask your printer what they need. Whichever you use, leave the clear margin around it that DENSO WAVE specifies: four modules wide on each side.

Lighting and placement

Conditions at the event can defeat a perfect design.

• Height. Place the code between waist and eye level. Nobody can scan comfortably above a crowd’s heads, or at knee height.
• Glare. Laminated posters and glass reflect light into the camera. Check at the time of day people will see it.
• Night events. Check how it reads under dim or coloured lights. Stage lighting can make dark and light areas harder to separate.
• Crowds. If people gather in front of a poster, repeat the code elsewhere, including near the queue.
• Mobile signal. Crowded venues can have poor reception. Keep your page light, and have a fallback, like a short address printed below the code.
• Weather. Outdoor flyers tear and fade. Protect or replace them.

Always include a short address in text, too. Some people prefer typing it in, and it’s a useful backup for a damaged code.

A page built for the event

Don’t send event traffic to your general page, where they’ll have to find the event among ten other options. A dedicated page keeps things simple. In BioFlow, you can add a separate page for an event, keeping your main one unchanged.

A useful order for an event page:

1. Event name, date, time and place at the top.
2. The main action: tickets, registration or RSVP, as a Link block to your ticketing service.
3. A map, using a Maps card that opens externally.
4. Schedule or line-up, in a text block or gallery.
5. A contact route for questions, such as WhatsApp.
6. A form or download, such as “Get the workshop notes”.

Keep it brief, since people are probably standing up, holding other things. Our guide to link in bio for small business has more ideas for local pages. If you’re also running a promotion on Instagram, giveaway comment automation shows how a comment-based entry can sit alongside your printed material.

One campaign per location

To compare locations, create a separate named campaign for each one. Each gets its own tagged address and its own QR code.

Here’s a made-up example for a pop-up market:

In Campaign performance, you’ll see views, clicks and Lead conversions for each one. BioFlow doesn’t count scans, so this is a comparison of visits rather than a scan total.

Be careful about what this tells you. If the café brought more visits than the gym, it might be the location, or it might just be that it had more foot traffic, or that the poster stayed up longer. Treat it as a hint, not proof. Read more about the method in QR codes for your link in bio, and about using the same approach with other channels in our cross-platform guide.

After the event

Your flyers will keep circulating, so plan for what happens when someone scans next month.

• Don’t unpublish or rename straight away. In BioFlow, both make the address return “not found”, and there’s no redirect. A dead end leaves a poor impression.
• Update the page instead. Replace “Get tickets” with “Thanks for coming”, then add photos and a link to what’s next.
• Offer a next step. Point people to your main page, your mailing list or your next event.
• Remove posters you’re responsible for. It’s courteous, and may be required by the venue.
• Look at your data. Note which locations brought visits, while you still remember the details.

After a few weeks, once scans have faded, you can retire the page. Export any leads first, because deleting a page removes its leads and its files.

FAQ

How big should a poster QR code be?

It depends on how far away people will stand, how dense the code is and the light. Rules of thumb vary between sources, so test instead of trusting a single number. Print a sample at real size, put it where it’ll hang and scan from the spot your audience will use, with more than one phone.

What makes people scan?

A clear, specific reason, placed beside the code. “Scan for tickets” or “Scan for the full line-up” works better than “Scan me”. It also helps if they know who’s behind the code, if they can reach it comfortably, and if what they get when they arrive matches what the poster promised.

Can I compare locations?

Yes, by giving each location its own tagged address. In BioFlow, create a named campaign per location, use each one’s QR code, and compare visits in Campaign performance. You won’t see scan counts, and a location’s foot traffic will affect results, so treat the comparison as a useful hint instead of proof.

Stand where they’ll stand

Before printing the full batch, tape one copy to the real wall, then step back and try scanning it. Fix what you find. You can create a QR code per location in BioFlow, or see its other features first.
