QR code guides and best practices

This guide explains the mechanics behind QR codes so you can make better decisions about payloads, styling, and scan reliability.

This is the main decision guide for QR type selection. Use it to match the user's goal after scanning to the most direct destination model.

Use this guide to create a QR code in the right order: choose the destination model, enter the final content, style it carefully, and test before publishing.

This page is the connective guide for the whole library. It brings together the recurring rules that matter across type selection, design, testing, and publishing.

Use this guide to understand where static QR codes work well, where they become rigid, and how that affects print, packaging, and long-term publishing.

This guide covers export-format selection. It explains when raster convenience is enough, when vector scaling matters, and when a document-style handoff is more practical.

This guide covers one high-intent comparison: whether the scan should open a live page, a hosted document, or a contact card.

This guide compares raw file links, media-specific generator pages, and landing-page approaches so you do not default every content handoff to a generic file URL.

This guide covers the reputation and feedback decision space: public review, private response, or score-based routing.

This guide covers payment QR decisions and safety: what to verify, how to avoid costly mistakes, and how different payment types shape user expectations.

This guide covers the messaging and contact-intent decision: immediate call, prefilled text, or chat-based handoff.

This guide helps you decide whether the scan should open one social profile, a focused set of social accounts, or a broader link hub with mixed CTAs.

This guide covers the contact-format decision: a richer contact payload versus a lighter one.

This is the core guide to QR code design. It covers readability-first styling decisions without drifting into print production or troubleshooting.

This guide focuses specifically on logo risk and logo placement. It is not a general design tutorial.

This guide focuses specifically on the role and tradeoffs of error correction. It is not a general troubleshooting page.

This guide covers print production logic: file handoff, material, contrast, layout, and physical output constraints.

This guide covers the QA workflow before print. It focuses on validation and approval, not on how to design or print the code in the first place.

This guide covers physical placement strategy across common surfaces. It explains where QR codes should sit in the real environment once the code itself is already designed.

This guide focuses specifically on size logic. It explains how distance, payload, and context change the minimum practical size.

This guide covers diagnosis and failure analysis. It is for isolating what broke once a QR code already exists.

This guide is scenario-specific. It explains how QR codes behave on business cards, where a very small surface has to carry identity, trust, and one clear next step.

This guide stays restaurant-specific: table context, low light, impatient guests, and the difference between browsing, ordering, and fixed document menus.

This guide is packaging-specific: durable destinations, material constraints, first-use usefulness, and long-lived support or onboarding flows.

This guide covers map intent, coordinates, venue navigation, and when a location QR is stronger than plain text or a general URL.

This guide focuses on Wi-Fi credentials, access context, and practical guest expectations rather than generic QR design advice.

This guide focuses on building a reliable contact-save payload: choosing the right fields, keeping them lean, and testing the saved-contact experience.

This guide covers app-install intent specifically: store routing, platform clarity, and when an app-store QR is a better fit than a URL or link hub.

This guide focuses on calendar-save event QR codes: title, date, time, location, completeness, and when an event payload is a better fit than a URL or PDF.
