What Is the Best QR Code Size for Printing?
Print size affects whether people can scan your QR code easily. The best size depends on viewing distance and how much information the code contains.
Use a practical minimum
For close-up use such as business cards, use at least 2 cm by 2 cm and leave a clear border around the code.
Increase size with distance
For posters and signs, make the code larger so people can scan it from where they naturally stand.
Test the final artwork
Print one sample, scan it in normal lighting, and check that the code remains sharp after export and printing.
