QR code size and error correction: a practical guide before printing

A QR code that looks good on a screen can still fail when printed too small, placed on a busy background, or scanned from far away. The safest approach is to plan size, contrast, and error correction before publishing.
Quick rules
- Use dark foreground on a light background.
- Keep a clear quiet zone around the QR code.
- Use higher error correction when adding a logo.
- Test the printed code with more than one phone.
Recommended workflow
Use the QR Code Generator to create the code, export it at a large size, and test the scan before sending artwork to print.

FAQ
Can I use brand colors?
Yes, but keep strong contrast. Light foreground on a dark background can work in some apps, but it is less reliable across scanners.
Can I place a logo in the middle?
Yes, if the logo is small and error correction is high. Always test before printing.
