Social Media and Text Accessibility

Social Media Accessibility

Best Practices Guide for Accessible Social Media Posts

(Compliant with WCAG 2.1 AA & Title II of the ADA)

Public entities must ensure that social media content is accessible to people with disabilities. This guide outlines best practices for making posts compliant with WCAG 2.1 AA and the DOJ’s 2024 Web Accessibility Rule.

1. Text Accessibility

  • Use plain, clear, and concise language (avoid jargon and complex wording).
  • Use CamelCase for hashtags (e.g., #PublicServices instead of #publicservices) so screen readers can read each word separately.
  • Provide descriptive link text (e.g., "Read our accessibility guide: [Link]" instead of "Click here").
  • Limit emoji use—screen readers read them aloud (e.g., "Smiling Face Emoji, Thumbs Up Emoji"). If used, place them at the end of a post. 
    Use proper punctuation and spacing to improve readability.

2. Image Accessibility

  • Always add alt text to images, explaining key visual details (Example: "City Hall entrance with a wheelchair-accessible ramp.").
  • Avoid text-heavy images (provide important information in the post text, not just in the image).
  • Use high contrast in graphics (avoid light text on light backgrounds).
  • For infographics or event flyers, provide a detailed text description in the post or link to an accessible PDF/HTML version.

3. Video & Multimedia Accessibility

  • Provide closed captions for all video content (auto-generated captions must be reviewed for accuracy).
  • Include transcripts for audio-only content (such as podcasts).
  • Use descriptive titles and captions to summarize video content.
  • Ensure flashing or animated content meets accessibility guidelines (Avoid flashing content over 3 times per second to prevent seizures).

4. Engagement & Interactive Content

  • Ensure polls and surveys are accessible (provide alternative text for images, label form fields, and use plain language).
  • If using GIFs, ensure they do not flash rapidly and provide a text description when necessary.
  • Respond to accessibility-related questions or requests promptly (e.g., if someone requests an alternative format).
  • If sharing third-party content, check if it is accessible or provide a summary in the post.

5. Platform-Specific Accessibility Features

Social Media PlatformKey Accessibility Features to Use

YouTubeClosed captions, audio descriptions, transcripts, and high-contrast thumbnails.

Final Accessibility Check Before Posting

  • Is all text easy to read and understand?
  • Does every image have appropriate alt text?
  • Are all videos captioned and audio content transcribed?
  • Are links descriptive rather than generic (“click here”)?
  • Have you used the platform’s built-in accessibility features?

By following these guidelines, public entities can ensure that their social media content is inclusive, compliant with Title II, and accessible to all users.

Content is Clear and Concise

Clear and easy to understand language will solve accessibility problems related to literacy. According to WCAG 2.0 AAA requirement 3.1.5, you should not use language above a lower secondary education level. While Texas State University adheres to level AA in most cases, we find that this particular AAA guideline is helpful. 

Use the list below as a quick reference to writing accessibly.

  • Use short sentences
  • Avoiding using font sizes below 12
  • Avoid using jargon
  • Use expanded acronyms on first use
    • For example, Student Learning Assistance Center (SLAC).
  • Provide a glossary when industry specific jargon is unavoidable
  • Use list formatting when appropriate
  • Visual representations of your ideas help convey meaning
    • Use video, audio, symbols and illustrations to assist with user communication

Readability

It is best to write page text at a high school level, when reasonable. Doing so benefits people with cognitive impairments, people who do not speak English as a first language and people who may be distracted while reading.

Some best practices for readability include:

  • Writing at a high school grade level, where possible and appropriate
    • Know your audience
  • Limiting paragraphs to around ~80 words
