Make It Scan on the First Try

📏 Print Big Enough

Print at least 2cm by 2cm (about 0.8 inches) for arm's-length scanning. Go larger for signs that get scanned from a distance. A rule of thumb: the code should be at least a tenth of the scanning distance.

⬜ Keep the Quiet Zone

StackQR generates black on white because that scans most reliably across lighting conditions. If you place the code on a colored background in a design tool, keep the area right around the code white. That white border is called the quiet zone, and scanners need it.

📱 Test on Two Phones

Test the printed result on at least two phones, not just the screen preview. Ink density and paper finish change scan behavior. A code that scans fine on a monitor can struggle on glossy paper under fluorescent light.

🏷️ Label the Code

Add a short label so people know what they're scanning. "Scan for WiFi," "Scan for menu," "Scan to pay." Two or three words remove the hesitation that loses casual scans.
