QR codes went from novelty to necessity during the pandemic, and they have stuck around because they work. For event organisers, QR codes bridge the gap between offline promotion and online ticket sales. A poster on a pub wall, a flyer on a community noticeboard, a banner at a festival — add a QR code and you have turned a passive advertisement into a direct link to your ticket page.
This guide covers how to use QR codes effectively in your event marketing, from design and placement to tracking and results.
How QR codes work for event marketing
A QR code is simply a scannable link. When someone points their phone camera at it, the code opens a URL in their browser. No app needed — every modern smartphone has a QR scanner built into the default camera.
For event marketing, the most common uses are:
- Linking to your event ticket page from printed materials
- Linking to a mailing list signup form
- Linking to your social media profiles
- Linking to an event schedule, map, or information page
- Linking to a feedback survey after the event
The ticket page link is by far the most valuable. Every poster, flyer, and banner you print should include a QR code that takes the scanner directly to where they can buy tickets.
Where to place QR codes for maximum scans
A QR code only works if people see it, can reach it, and have a reason to scan it. Placement matters more than design.
On posters and flyers
- Position the QR code in the bottom-right corner or centre-bottom of the poster. This is where people naturally look after reading the main content.
- Make it large enough to scan easily. A QR code on a poster should be at least 3cm x 3cm. On a flyer, at least 2cm x 2cm. Bigger is always better — if someone has to hold their phone two inches from the poster, you have made it too small.
- Leave white space around the code. QR codes need a clear margin (called the "quiet zone") to scan reliably. Do not overlap the code with background images, patterns, or text.
- Add a call to action next to it. A QR code alone does not tell people what happens when they scan it. Add text like "Scan for tickets," "Scan to book," or "Scan for full lineup." Without context, many people will not bother.
At venues and in-person locations
- Bar and counter tops — Table cards or tent cards with a QR code at bars, cafes, and restaurants near your venue or in the local area. "Like live music? Scan for upcoming shows."
- Venue entrance and foyer — Display a QR code linking to your next event at the current event. People leaving a great show are primed to book the next one.
- Toilet doors — It sounds odd, but toilet door posters get high engagement because people are standing still with their phone in their hand. Many venues sell this space for event promotion.
- Merch tables and registration desks — Display a QR code linking to your mailing list signup. Capture contact details while people are engaged.
- Event screens — If your venue has screens or projectors, display a QR code between acts or during intervals. Link it to your next event or your mailing list.
On merchandise and physical items
- Wristbands — Some wristband suppliers can print QR codes directly on event wristbands.
- Drink tokens or vouchers — If your event uses physical tokens, print a QR code on the back linking to your website.
- Business cards — Hand out cards at industry events or meetings with a QR code linking to your event portfolio or upcoming listings.
Creating effective QR codes
Free QR code generators
You do not need to pay for QR codes. Several free tools create them in seconds:
- QR Code Generator (qr-code-generator.com) — Simple, free, and supports custom colours.
- QRCode Monkey — Free with logo embedding and colour customisation.
- Google Charts API — For developers, Google offers a simple API to generate QR codes programmatically.
- Canva — Has a built-in QR code generator if you are already designing your poster there.
Design tips
- Keep it simple. A standard black-on-white QR code scans the fastest and most reliably. Custom colours and logos look nice but can reduce scan reliability if the contrast is too low.
- Test before printing. Always scan your QR code on at least two different phones before sending it to the printer. Test in different lighting conditions. A code that works on your screen might not work on a poster under pub lighting.
- Use a short URL. Longer URLs create denser QR codes that are harder to scan at small sizes. Use a URL shortener (like Bitly) or a clean URL structure.
- High contrast is essential. Dark code on a light background works best. Avoid light grey on white, or dark blue on black. The scanner needs clear contrast to read the pattern.
Tracking QR code performance
One of the biggest advantages of QR codes over traditional print advertising is that you can track them. A poster on a pub wall is no longer a guessing game — you can see exactly how many people scanned it.
How to track scans
- Use UTM parameters. Add UTM tags to the URL your QR code points to. For example: yoursite.com/events/summer-party?utm_source=poster&utm_medium=qr&utm_campaign=pub-promo. This lets you see in Google Analytics exactly how many visitors came from that specific QR code.
- Use a URL shortener with analytics. Bitly and similar services show you how many clicks a shortened link received, when they happened, and from what location. Create a unique short link for each QR code placement.
- Use different QR codes for different locations. Print a different QR code (with a different UTM tag or short link) for each placement location. This tells you whether the pub poster or the gym flyer drove more scans.
What to measure
- Scans (clicks) — How many people scanned the code.
- Conversions — How many of those scanners actually bought a ticket. This is the number that matters.
- Scan-to-purchase rate — Divide conversions by scans. If 100 people scan and 5 buy, that is a 5% conversion rate — which is actually quite good for offline-to-online.
- Location performance — If you used different codes for different locations, compare which spots drove the most scans and the most sales.
Common QR code mistakes
- Making the code too small. This is the most common error. If someone cannot scan it from arm's length, it is too small.
- Linking to the wrong page. Your QR code should link directly to the ticket page for the specific event, not your homepage, not your "all events" page. Reduce friction — every extra click loses potential buyers.
- Not including a call to action. A QR code without context is a mystery box. Tell people what they get when they scan.
- Forgetting to test. Print a test page and scan it before ordering 500 posters.
- Using a QR code that expires. Some generators create "dynamic" codes that stop working after a trial period. Use a direct URL or permanent short link.
- Linking to a non-mobile-friendly page. The person scanning is on their phone. Tickts and most modern ticketing platforms are mobile-friendly by default, but always check.
Creative QR code ideas for events
Beyond the standard poster-to-ticket-page use, here are some creative ways event organisers are using QR codes:
- Scavenger hunts — Hide QR codes around a festival site, each linking to a clue or prize. This gamifies the event and creates buzz on social media.
- Feedback collection — Display a QR code at the exit linking to a short feedback survey. "Scan to tell us what you thought — takes 30 seconds."
- Contactless tipping — For performers at open-mic nights or busking events, a QR code linking to a payment page replaces the tip jar.
- Schedule and map — For festivals and multi-stage events, a QR code linking to a digital schedule or site map saves printing costs and allows real-time updates.
- Sponsor integration — Offer sponsors a QR code on their banner that links to their offer or website. This gives sponsors measurable ROI from their sponsorship.
Printing considerations
A few practical notes on print quality:
- Use vector format (SVG or PDF) when possible. This ensures the code stays sharp at any size. Avoid low-resolution JPEG or PNG for large posters.
- Matte paper scans better than glossy. Glossy paper creates glare under lights, making codes harder to scan.
- Dark backgrounds require a white border. Make sure the QR code sits within a white box with adequate padding.
QR codes are a simple, low-cost tool that can meaningfully increase ticket sales from offline marketing. Print them on everything, track the results, and double down on the placements that work.
