Use the Accessibility Checker
PowerPoint includes a built-in Accessibility Checker to help identify and fix accessibility issues. This tool runs in real-time and can be accessed through the "Review" tab. While it won’t catch everything, it’s a great starting point for creating inclusive presentations.
Add File Metadata
Improve clarity by adding metadata such as a meaningful title, file name, and language settings. You can update these details under the "File" menu in the "Info" section to make your presentation easier to identify and use.
Use a Clear Slide Structure
- Organize slides with proper heading levels and ensure a logical reading order.
- Use slide titles to provide a clear structure, and avoid skipping levels in text hierarchy.
- Stick to predefined slide layouts, as they are optimized for accessibility.
Format Text for Readability
Use a sans-serif font, set line spacing to at least 1.5, and left-align text whenever possible. Maintain a font size of at least 18pt for body text and 24pt or larger for headings to ensure readability.
Use Bullet Points for Clarity
Break down information into concise bullet points rather than long paragraphs. Lists help create a clear structure and make content easier to scan and understand.Write Clear and Descriptive Links
Ensure hyperlinks have meaningful text that describes their destination, rather than generic phrases like “Click here.” If sharing printed slides, consider including both the descriptive link and the full URL.
Add Alt Text to Images and Graphics
Provide alternative text for all important images, charts, and graphics to ensure users with visual impairments can understand the content. Keep descriptions brief and informative, avoiding phrases like "image of" or "graphic of."
Ensure High Color Contrast
Use colors with strong contrast between text and background to improve readability. The recommended contrast ratio is at least 4.5:1 for standard text. Accessibility checkers and color contrast tools can help verify compliance.
Avoid Using Color Alone to Convey Meaning
Ensure that meaning is not solely communicated through color. Use additional indicators such as text labels, patterns, or icons to make your slides accessible to those with color vision deficiencies.
