A Practical Accessibility Checklist (Beyond WCAG Basics)

Most accessibility checklists cover the basics like contrast, alt text, and keyboard navigation. We want to go further. Our checklist looks at the practical, human-centered details that often get missed.

This list isn’t just about ticking boxes. It’s about making sure people can use and trust your product in real life. We’ve added extra detail where most checklists stop. These are the small things that often get overlooked.

Our checklist covers sensory, cognitive, emotional, and contextual aspects of accessibility. While WCAG 2.2 provides an essential technical standard for digital accessibility, we go further by addressing areas it often leaves out—like emotional accessibility, trust, and real-world usability. This helps teams build experiences people can actually use and trust in real situations.

Use this checklist during:

• Design reviews
• QA testing
• Content creation
• Usability testing

Checklist

1. Sensory & Cognitive Accessibility

• Break information into steps so users aren’t overwhelmed. Show only what’s needed at each stage.
• Prioritize content. Put the most important information first, especially on dense pages.
• Limit motion. Avoid flashing or looping animations, and provide a pause option.
• Avoid justified text. Uneven spacing can make reading harder, especially for people with dyslexia.
• Check line spacing and word spacing. Text should feel easy to scan—not cramped or stretched.
• Make time limits visible and flexible. Let users extend time when needed.
• Avoid unexpected changes like auto-submit or auto-advance. Users should stay in control.

2. Micro-interactions & Feedback

• Don’t rely on color alone for errors. Make sure messages are clearly associated with fields and announced to assistive technologies.
• Confirm actions in more than one way—visual, sound, or touch—so users don’t have to guess what just happened.
• Keep tooltips and hover/focus states visible until dismissed. Give users time to read.
• Do not rely only on placeholder text for form instructions. Include instructions outside the field so they are consistently available.

3. Navigation & Orientation

• Make sure every page has a clear, descriptive title so users know where they are.
• Use headings, landmarks, and breadcrumbs to provide structure—not just visual layout.
• Add skip links beyond “main content,” including filters, comments, or other repeated sections.
• Test sticky headers and footers at high zoom. They shouldn’t block content or trap focus.
• Keep navigation consistent across pages so users don’t have to relearn your interface.
• Match tab order to how people read the page—not just how it’s built.

4. Media & Alternative Formats

• Add audio descriptions when important visual information is not already communicated through dialogue or narration. For prerecorded video, WCAG Level AA requires audio descriptions when users would otherwise miss meaningful visual content.
• Include meaningful sound cues in transcripts (for example: [music playing], [door slams], [audience laughing]). This helps people understand the full context.
• Summarize complex content in a way that is easy to read. Use short sentences and highlight the main points.
• Write alt text for infographics that communicates the main insights, not just the visuals.
• Add speaker labels to video captions when more than one person is talking.
• Let users download data tables for charts, not just view the graphs. Offer formats like CSV or Excel.

5. Device & Context Awareness

• Test at 200%–400% zoom. Your layout should still work without loss of content or function.
• Test with voice navigation and speech input tools, including Dragon, Voice Access, Voice Control, and other device-native speech interfaces.
• Provide a non-drag alternative for drag-and-drop actions, such as using arrow keys and the spacebar.
• Design for unreliable conditions—slow internet, no JavaScript, limited bandwidth.
• Avoid interactions that require precision. Small targets exclude people.
• Make touch targets large enough to hit comfortably. WCAG 2.2 sets a minimum of 24×24 CSS pixels, but 44×44 CSS pixels is often a better target for mobile usability.

6. Inclusive Language & Cultural Accessibility

• Avoid idioms that don’t translate across cultures.
• Do not rely on color alone to show meaning. Color perception and meaning can vary.
• Use plain language first. Add complexity only when needed.
• Use gender-neutral language where possible.
• Write content that can be translated easily. Don’t embed critical text in images.

7. Error Recovery & Control

• Be specific about irreversible actions. “Are you sure?” isn’t enough.
• Let users undo actions instead of forcing them to start over.
• Allow progress to be saved, especially in longer workflows.
• Clearly distinguish required vs. optional fields.
• Show all errors at once so users can fix them efficiently.
• Ensure security and verification processes have accessible alternatives. CAPTCHAs, multi-factor authentication, and identity verification steps should not prevent people from accessing or completing tasks.

8. Testing with Real People

• Include people with a range of disabilities—not just one group.
• Test in real conditions: glare, noise, distractions, poor connectivity.
• Include situational limitations (injury, multitasking, environmental constraints).
• Test across devices—not just the latest ones.
• Test combinations of assistive technology (for example, screen reader + magnifier).
• Review AI-generated content for clarity, accuracy, and accessibility. Automated content can introduce confusing language, missing context, or inaccessible descriptions.

9. Trust, Control & Emotional Accessibility

Accessibility isn’t just functional—it’s emotional.

If users don’t feel safe, respected, and in control, the experience breaks down.

• Avoid dark patterns like fake urgency, hidden fees, or misleading actions.
• Make sure buttons and links do what they say.
• Write error messages that help—not blame. Tell users what to do next.
• Offer multiple ways to get help so users can choose what works for them.

10. Accessibility Beyond the Screen

• Make physical materials accessible—clear print, strong contrast, scannable codes.
• Ensure event experiences are accessible end to end, not just the presentation.
• Prefer accessible web pages over PDFs when possible. When PDFs are necessary, ensure they are properly tagged, structured, and readable.

Final Thought

Accessibility is not a checklist you complete. It’s a standard you maintain.

The gaps that matter most aren’t always caught by automated tools or basic reviews. They show up when real people try to use your product in real situations.

Build with that in mind.

Because if someone can’t use your product when it matters, it doesn’t work.
