QR guides

Practical QR code guides

Learn how QR codes work, how to test them, how to size them for print, and how to avoid common QR code mistakes.

Start here

Learn what QR codes store, when static QR codes are enough, and how to create a link QR code without overcomplicating the workflow.

Print with confidence

Use sizing, contrast, quiet zone, and final proof checks before ordering menus, signs, flyers, cards, labels, or packaging.

Use QR codes safely

Set expectations with clear labels, trusted destinations, accessible alternatives, and careful handling for payment or login-adjacent links.

Guide decision path

Start with the cornerstone that matches the next decision you need to make. Each path links to supporting guides, a practical tool, relevant use cases, and the generator only when the destination is ready.

QR creation and formats

Start here when the main question is what the QR code should encode and whether a static code is enough.

Cornerstone guideWhat Is a QR Code?A QR code is a two-dimensional barcode that stores data in square modules so a camera or scanner can decode a URL, text, Wi-Fi login, contact card, event, or other supported payload.Supporting guideStatic vs Dynamic QR CodesA static QR code directly contains the final data; a dynamic QR code usually contains a managed redirect URL whose final destination can be changed by the provider.Supporting guideHow to Create a QR Code for a LinkTo create a QR code for a link, use a full public http or https URL, paste it into the Website URL QR type, download SVG or PNG, and test the full destination on mobile.

Printing, size and contrast

Use this cluster before ordering business cards, flyers, posters, stickers, packaging, menus, or signs.

Cornerstone guideBest QR Code Size for PrintA practical starting point is to size the QR code at about one tenth of the expected scan distance, then increase it for dense payloads, glossy material, poor lighting, or moving scanners.Supporting guideQR Code Design Best PracticesGood QR design protects scan reliability first: dark foreground, light background, clear quiet zone, adequate size, restrained decoration, and a printed test before launch.Supporting guideQR Code Mistakes to AvoidThe most common QR code mistakes are broken destinations, private links, low contrast, tiny print size, missing quiet zone, unclear labels, and skipping a real scan test.
