Adding a logo to a QR code without breaking it
A small logo in the center of a code is the most common customization — and the easiest way to make a code unreliable. Three rules keep it safe.

The three rules
Keep the logo small, raise error correction, and give it a background plate. Those three together mean the scanner treats the covered modules as damage it can reconstruct.
- Logo no larger than about a fifth of the code
- Error correction at Q or H
- A solid background plate behind the logo
Why the quiet zone still matters
The logo sits in the middle, but the margin around the code is just as important. Keep the quiet zone clear of the logo, borders and text, or the scanner struggles to find the code at all.
Frequently asked questions
How big can a logo be in a QR code?
Around 20% of the code area is a safe ceiling with high error correction. Bigger than that and reliability drops fast.
Does a logo make a code unreadable?
Not if you keep it small and raise error correction. Always test on two phones before printing.
Can I use an emoji or a glyph instead of a logo?
Yes — a single emoji works the same way, and the same size and error-correction rules apply.
