To ensure QR codes scan reliably when printed, it’s essential to choose the correct size.
Recommended QR Sizes
- For business cards: 20-25mm (0.8–1.0″).
- For larger prints like posters: 50–80mm (2.0–3.1″).
- For table tents: 30-45mm (1.2–1.8″).
Important Considerations
- Ensure the QR code is placed on a flat, matte surface to avoid reflections and glare.
- Keep enough quiet zone around the QR code to avoid interference with the background.
Testing Your QR Size
Test the printed QR code at a real scan distance (e.g., 30-50 cm for business cards) to ensure it scans reliably.
Exact mm/in recommendations, quiet zone rules, and print tips so your QR scans fast on real phones from typical distances.
When SVG is mandatory (printing), when PNG is fine (screens), and how resizing affects scan reliability.
Why quiet zone is non-negotiable, how to choose colors that scan, and what backgrounds (patterns, gradients) break QR detection.
Best size for table tents and wall posters, avoiding glare, and a practical checklist for menus that scan instantly in real lighting.
Pick the right error correction level for print/screens/logos. Learn the trade-off: higher correction = denser QR = needs larger print.
