Logo in the middle of a QR code: how much room is safe
Error correction lets you cover part of a QR code with a logo. But there is a limit — and it is smaller than most people think.
How much space the logo may take
Level H recovers up to 30% of a damaged code. In practice that does not mean you can cover a third of it.
Stay at 20–25% of the area and keep the logo dead centre — that is where the spare modules sit, not where the corner markers are.
What the logo should look like
A simple solid silhouette reads better than thin lines, serifs or small text inside the mark.
Avoid transparency: a semi-transparent logo blends with the modules and turns them into grey noise.
When to shrink the logo
Dense codes — a long link, a vCard, Wi-Fi details — have smaller modules, so the same logo eats more of the useful area.
Test on a real printout at real size, not on screen. That is where you see whether the contrast still holds.
