QR Code Error Correction & Printing Best Practices

QR codes feature four error correction levels (L: 7%, M: 15%, Q: 25%, H: 30%). Higher error correction levels allow QR codes to remain scannable even if partially damaged or obscured by stickers or logos.

When printing QR codes on round stickers like Avery 22806, ensure your QR module width is at least 0.75" x 0.75" (19mm x 19mm) to allow smartphone cameras to focus instantly without optical distortion.
