Size Depends On Distance
A QR code on a business card can be small because people scan it nearby. A code on a counter sign, poster, table tent, or window needs to be larger. If the scan distance doubles, the printed code usually needs to grow too.
Protect The Quiet Zone
The empty margin around a QR code is part of the code. Text, borders, logos, and background patterns should not touch it. A clean quiet zone helps phone cameras separate the code from the design around it.
Use Strong Contrast
Dark modules on a light background remain the safest choice. Brand colors can work, but low contrast, gradients, and glossy paper can make scanning slower. Test the final artwork under real lighting before printing many copies.
Add A Clear Label
People are more likely to scan when they know what will happen. A label such as Scan for menu, Save our contact, or Open product guide creates trust and reduces hesitation.
Start With Scan Distance
QR print size depends on how far away the scanner will be. A code on a menu can be smaller because people hold it nearby. A code on a poster, window sign, or counter display needs more physical size and clear spacing. If people must step closer or zoom their camera, the code is too small for the placement.
Design Rules for Print
Use strong contrast, keep a clean quiet zone around the code, and avoid placing it over textured backgrounds. Decorative colors are fine only when testing proves they scan in real lighting. Glossy paper, low ink, folds, and curved surfaces can all reduce scan reliability, even if the digital preview looks perfect.
Final Testing Checklist
Print one sample at final size before ordering many copies. Test it with at least two phones, from the expected distance, under the same lighting where it will be used. Confirm the landing page loads quickly on mobile and matches the printed promise, such as menu, booking page, WiFi login, or contact card.
