Best practices for printing QR codes

Use a QR code that’s at least 31 mm × 31 mm (1.22 in × 1.22 in).
For business cards, placing the QR code on the back helps maintain a clean layout.
Avoid placing it near the edges, where it could be trimmed.
If you upload your own QR code, make sure the file is high-resolution and at least 300 dpi.
