Error Correction Levels
QR codes include error correction, allowing them to be read even if partially damaged. Higher error correction means larger QR codes but more reliability:
Low (L): ~7% recovery - smallest size, use for clean environments.
Medium (M): ~15% recovery - balanced choice for most uses.
Quartile (Q): ~25% recovery - for printed materials.
High (H): ~30% recovery - best for adding logos or outdoor use.
FAQ
What size should my QR code be?
For print, the minimum size depends on scanning distance. A 1-inch (2.5 cm) QR code works for up to 10 inches away. For posters scanned from several feet away, use at least 3-4 inches.
Can I use any colors?
The foreground should be darker than the background for best scanning. Black on white is ideal. Avoid low-contrast combinations and inverted colors (light on dark).
PNG vs SVG - which format?
PNG is best for web use and social media. SVG is vector-based and scales perfectly for print at any size without quality loss.
