A Guide to QR Code Accessibility: Making Scans Usable for Everyone

In our rush to adopt new technologies, it's easy to overlook a critical question: is it accessible to everyone? QR codes, while convenient for many, can present significant barriers for people with disabilities, particularly those with visual impairments or motor difficulties. A QR code is useless if a person cannot see it, scan it, or use the content it links to.

Creating an accessible QR code experience is not just about compliance; it's about inclusive design and ensuring your message can reach the widest possible audience. This guide covers the essential best practices for QR code accessibility.

1. Physical Placement and High Contrast

The first step is ensuring the user can find and scan the code.

• Predictable Location: Place QR codes in a consistent, predictable location. For example, on restaurant menus, always place it in the top right corner.
• High Contrast: This is crucial for people with low vision. A crisp, black code on a solid white background is the most accessible option. Avoid using light colors or complex backgrounds.
• Matte Finish: Print codes on non-glossy (matte) surfaces to prevent glare, which can make scanning difficult for everyone, especially those with vision impairments.
• Appropriate Size: The code must be large enough to be easily detected by a phone's camera from a reasonable distance. A minimum of 1x1 inch is a starting point, but larger is better.

2. Provide a Non-Digital Alternative

A QR code should never be the only way to access essential information. Always provide an alternative.

• Include a Short URL: Print a short, easy-to-read URL directly below the QR code (e.g., your.site/promo). This allows someone who cannot scan the code to type the address manually.
• Provide Clear Instructions: Include simple text like, "Scan the QR code or visit your.site/menu to view our menu." This helps users who may not be familiar with QR codes.


3. Ensure Your Linked Content is Accessible

An accessible QR code is pointless if it leads to an inaccessible website or document. The destination page is the most critical part of the experience.

• Mobile-Friendly Design: The linked page must be optimized for mobile devices with large, readable fonts and easily tappable buttons.
• Screen Reader Compatibility: The website or document must be properly coded so that screen readers (software used by blind individuals) can read the content aloud in a logical order. This includes using proper headings (H1, H2, etc.) and adding 'alt text' to all images.
• PDFs Must Be Tagged: If you link to a PDF, it must be a 'Tagged PDF' for accessibility. An untagged PDF is just an image to a screen reader, making it completely inaccessible. Most modern word processors can export accessible, tagged PDFs.

4. Add a Text-Based Call to Action

Don't assume a user knows what the QR code is for. A clear call to action helps everyone, especially users of assistive technology.

• Be Descriptive: Instead of just "Scan Me," use descriptive text like, "Scan here to download our accessible PDF menu" or "Scan to watch the video with audio descriptions."

By thinking inclusively, you can leverage the convenience of QR codes without excluding a significant portion of the population. Accessibility isn't an extra feature; it's a fundamental part of good design.
