1. Distance Math

Visitors usually scan from 1 to 3 meters. At the 10:1 rule, that means 10 to 30 cm. Crowded halls and poor lighting justify the conservative 8:1 ratio, so budget 15 to 40 cm.

2. Placement

* Position the code between chest and eye level (about 120 to 160 cm from the floor). * Keep it away from the bottom third, where people block it. * Leave a clear quiet zone; do not overlap it with graphics.

3. Call to Action

State what the scan delivers ("Scan for the 2-minute demo"). Large banners also help to include a short typed URL as a fallback.

4. Printing

Use vector files at the finished banner size and matte material to limit glare from booth lighting.
