Why PowerPoint Accessibility Matters
Presentations are a primary teaching and communication tool in medical education. Accessible PowerPoint presentations ensure that all students can follow along, whether they're attending in person, viewing slides online, or reviewing materials later with assistive technology.
Using the Accessibility Checker
PowerPoint includes a built-in accessibility checker to identify and fix common issues.
Use the Accessibility Checker- Click the Review tab
- Click Check Accessibility
- Review the Accessibility pane that appears on the right
- Click on each issue for recommendations
- Address issues as you build your presentation
Using Slide Layouts
Built-in slide layouts ensure proper reading order and structure. Never create slides from blank layouts.
- Click the slide you want to format
- Go to the Home tab
- Click Layout in the Slides group
- Choose an appropriate layout (Title Slide, Title and Content, etc.)
- Add your content to the placeholders provided
Creating Meaningful Slide Titles
Every slide must have a unique, descriptive title. Screen reader users navigate presentations by slide titles.
- Make every slide title unique and descriptive
- Keep titles concise but informative
- Never leave the title placeholder empty
- If you don't want the title visible, hide it (don't delete it)
Checking and Fixing Reading Order
Reading order is the sequence in which screen readers announce slide content.
- Go to the Home tab
- Click Arrange in the Drawing group
- Select Selection Pane
- The Selection Pane shows objects in reading order (bottom to top)
- Drag items to reorder if needed
- Title should be read first
- Content should flow logically (top to bottom, left to right)
- Using built-in layouts helps maintain proper reading order
Adding Alternative Text to Images
All meaningful images, charts, diagrams, and SmartArt need alternative text descriptions.
- Right-click the image, chart, or SmartArt
- Select View Alt Text
- Type a concise description in the Alt Text pane
- For decorative images, check "Mark as decorative"
- For charts/graphs, describe the key trends and data points
- For diagrams, explain the relationships shown
- Consider adding a text summary on the slide for complex visuals
Using Tables Properly
Tables in PowerPoint must have designated header rows for accessibility.
- Insert a table using Insert → Table
- Fill in the header row with column titles
- Select the table
- Go to Table Design tab
- Check the Header Row box
Creating Accessible Hyperlinks
Link text should describe where the link goes, not just say "click here."
- Select the text to become a link
- Press Ctrl+K (or Cmd+K on Mac)
- Enter the URL
- Ensure the "Text to display" is descriptive
- Click OK
Using Color and Contrast
Ensure slides are readable with sufficient color contrast and don't rely on color alone.
- Use high contrast between text and background
- Avoid placing text over busy background images
- Don't rely solely on color to convey information
- Use text labels in addition to color coding
- Test your slides by viewing in grayscale
Font and Text Formatting
Choose fonts and formatting that enhance readability.
- Use sans-serif fonts (Arial, Calibri, Helvetica)
- Minimum font size: 18-20 points for body text
- Avoid all caps (harder to read)
- Limit italics and underline
- Use bold for emphasis sparingly
- Ensure adequate line spacing
Audio and Video Accessibility
Multimedia content requires additional accessibility considerations.
- Provide captions for all video content
- Include transcripts for audio
- Don't set media to autoplay
- Provide accessible media controls
- Describe important visual content that isn't in audio
