At a trade show or event, a banner QR code should sit at hand height where visitors can scan without stopping the crowd, and it should open one clear next step: book a demo, get the brochure, or join the list. Most booth codes fail because they are printed too small, placed too high, or sent to a desktop-only page.
Where do banners and signage actually get scanned?
| Item | Typical viewing distance | Starting code width |
|---|---|---|
| Table-top sign or counter card | 0.5 to 1 m | 5 to 8 cm |
| Retractable (roll-up) banner | 1 to 2 m | 10 to 15 cm |
| Backwall or large booth graphic | 2 to 4 m | 20 to 30 cm |
| Hanging banner overhead | 5 m or more | Not for scanning; use for brand only |
These are planning figures from the ten-to-one rule of thumb. Print a proof and test it from the real standing spot. The print size guide shows the method.
How high should the code be?
Between hip and chest height, roughly 100 to 150 cm from the floor. A code at eye level on a tall banner is often blocked by people queuing, and a code near the floor gets hidden by bags and furniture. Never put the only code above head height.
What should a booth code open?
- One action per code. Choose between "Book a demo", "Download the brochure" and "Enter the prize draw", and label it. Several equal codes on a banner confuse visitors.
- A mobile-first page. Conference Wi-Fi and mobile data are often slow. Keep the page light and the form short.
- A lead capture that links to your CRM. A QR code makes it quick to start the conversation; the form is where you get the contact.
- A vCard for staff badges or business cards. See team business cards.
How do you design a banner code that survives vinyl and fabric?
- Use a solid dark colour on a light block with the full quiet zone, not a tinted overlay. See the colour guide.
- Choose matt vinyl or fabric to avoid exhibition-hall spotlights bouncing off the code.
- Export SVG for large-format printers. Raster files blur when enlarged.
- Keep roll-up banners taut. Creases and wavy fabric distort the pattern.
How do you measure event response?
Use a separate dynamic QR code for each event, and ideally for each banner. After the show, compare scan counts across events and banner positions with tracking, and tag the landing URL so your analytics shows which show produced leads. You can then repoint the same banners to the next event's page without reprinting.
