Improve Slide Readability
Readable slides help all viewers, including those with visual impairments, access and understand your content.
- Use simple sans-serif fonts such as Arial, Calibri, or Aptos.
- Use a font size of at least 18 pt for body text and 24 pt or larger for headings.
- Maintain strong contrast between text and background.
- Avoid overcrowding slides with excessive text, images, or visual elements.
- Use clear, direct language and avoid unnecessary jargon.
Tip: View your slides in full-screen mode to confirm that text is easy to read from a distance.
Use Built-In Slide Layouts
Built-in PowerPoint layouts help create structure that can be interpreted more reliably by assistive technologies.
- Go to the Home tab and select Layout.
- Choose a built-in layout that matches the purpose of your slide.
- Use placeholders for titles, body text, and images whenever possible.
- Avoid creating slides entirely from manually inserted text boxes.
- Avoid overlapping text, images, and shapes.
Tip: Built-in layouts improve consistency, readability, and screen reader navigation.
Add Alt Text for Images
Alt text describes meaningful images for participants who cannot see them or who use assistive technology.
- Right-click the image.
- Select Edit Alt Text.
- Write a concise description of the image and its purpose.
- Mark the image as decorative if it does not communicate important content.
Example: “A line graph showing enrollment growth from 2020 to 2025.”
Tip: Avoid starting descriptions with “image of” or “picture of.”
Check Reading Order
Reading order determines how slide content is interpreted by screen readers and other assistive technologies.
- Open the slide you want to check.
- Go to the Review tab and select Check Accessibility.
- Use the reading order or selection tools to review the order of slide objects.
- Confirm that the title comes first, followed by the main text and supporting visuals.
- Move objects into a logical order if needed.
Tip: A logical reading order usually follows the same order a person would naturally read the slide: title first, then main content, then supporting details.
Run a Final Accessibility Check
Before sharing your presentation, use PowerPoint’s Accessibility Checker to find common issues such as missing alt text, poor reading order, unclear slide titles, or low contrast.
- Go to the Review tab.
- Select Check Accessibility.
- Review the inspection results.
- Correct any issues that PowerPoint identifies.
- Save your updated file.
