QR code error correction and size
Higher correction tolerates damaged prints; larger modules scan faster on posters.

Key takeaways
- Marketing posters need higher error correction than clean digital screens.
- Test scan distance with the actual printed size, not zoomed PDFs.
Error correction levels
Use higher levels when logos overlay the code or when outdoor signage may scratch.
Digital-only flows can use lower correction for denser codes at small sizes.
FAQ
URL too long?
Longer payloads increase module count—shorten with your own redirect domain when possible.
SVG vs PNG?
PNG is universal for slides; SVG scales for print if your pipeline supports it.
