QR codes for print and events: a practical checklist
A QR code is a tiny doorway. If it is blurry, cramped, or pointed at last month’s page, people do not admire the design system—they leave.
Shorten before you generate
A short destination produces a cleaner matrix and gives error correction more room to work. SOSU.SU generates the QR locally, keeps branding outside the data area, and leaves the quiet zone alone. The code gets one job and the decorative ambition waits politely at the edge.
Use the format that fits the medium
Download SVG for print layouts because it stays crisp at different sizes. Use PNG for slides, chat, or a quick digital mockup. Keep strong contrast and test at the final physical size; a code that works on a 27-inch monitor may become abstract art on a two-inch badge.
Plan for change
Use a 302 short link when the printed piece may outlive the destination page. You can update the target without replacing every poster or package. Scan the proof with more than one phone, verify the landing page over cellular data, and write a human label beside the code so visitors know what happens next.
