Start with scanning distance
The right QR code size depends on how far away the viewer is when they notice it. A code on packaging can be smaller than one on a window or poster because the user holds the package in hand. Thinking in terms of scan distance helps you avoid one-size-fits-all design mistakes.
Protect the quiet zone
The quiet zone is the blank margin around the code. It is not optional. When logos, borders, background patterns, or crowded text enter that area, scan reliability drops. Many broken print campaigns happen because designers style the code too aggressively and squeeze out the blank space that scanners rely on.
Use contrast and stable surfaces
Dark code on light background remains the safest option for print. Avoid placing QR codes over photos, gradients, textured patterns, or reflective materials unless you test them thoroughly. Curved packaging, glossy surfaces, and low-light environments all deserve extra testing before rollout.
Place the code near the action
The best position is where the next action makes sense. A poster for event registration needs the code near the event details. A product package might place the code near setup instructions or warranty information. Good placement helps users understand both the purpose and the timing of the scan.
Build your QR code
Create a fast static QR code with QRTOOL.tech and export it as PNG or SVG for print, packaging, displays, and campaigns.
Open QR generatorsWhat should a design tips QR code link to?
It should link to the shortest, clearest destination that matches the user intent behind the scan. Avoid extra clicks and generic homepages whenever possible.
How do I improve scan rate?
Use high contrast, enough size for the viewing distance, a visible call to action, and a mobile-friendly page that loads quickly.
Should I test before printing?
Yes. Test the final design on real phones, in real lighting, and on the actual print material whenever possible.
