Create Accessible Google Slides

These are steps to use the Grackle Accessibility Checker to create accessible documents in the Google Workspace. Grackle is a third-party service that scans your Google Docs/Slides/Sheets for accessibility issues and guides you through the remediation process.

The Grackle Accessibility Checker is are currently available for users with google accounts with or email addresses.

For users without access to Grackle, the steps below may still be used to create an accessible document. The only difference is you will not be able to use the automated check feature. For any questions, contact

1. Use an Accessibility Checker

Use automated accessibility checkers to help you spot and fix accessibility errors while you work.

While automated checkers won’t catch every issue, they are a great tool to have in your tool set and are a good reminder that we should be thinking about accessibility when creating or editing content.

2. Add File Metadata

Add Metadata for your file to clearly identify it to your audience. Give the file a clear title and file name. Identify the language of the document.


In your program, modify the displayed file name and navigate to File settings to change the language.

3. Write Unique and Descriptive Slide Titles

Slide titles provide an outline and improve navigation making your document more accessible. Each slide should have a unique title. For slides that may be on the same topic, try something like Goals 1 of 3, Goals 2 of 3, Goals 3 of 3.

4. Format Text for Legibility

Format your text so that it is easier for your audience to read. Consider using a sans serif font, setting line spacing to 1.5. Keep text left-aligned when possible to allow users to easily identify new lines. Keep font at a standard size or larger. For documents, that is 11pt and for slide presentations 18pt.

5. Break Content into Lists, Where Possible

Browse your document to see if any paragraphs would be easier to read as a list.Lists make content easier to read by providing visual structure and highlighting key points.


Use the Pargraph Panel to select a bullet or numbered list.

6. Write Descriptive Links

Write link text so that it is unique, descriptive, and clear about where the link goes. If sharing documents for printing, consider including both a descriptive link and the full link text. Find additional guidance: How to Write Helpful Links.


Select and highlight the text you would like to link. Right click and chose edit link text.

7. Add Alt Text to Images

Add alternative text for all non-decorative images to convey the equivalent information to someone who may not be able to see the image. Keep it short and descriptive, like a tweet. Don’t include “image of” or “photo of”. For some examples, visit our page on alt text.


In most programs, right-click on image to bring up a menu with the options "Add Alt Text" or "Edit Image."

8. Use High Color Contrast

Choose a color for your text and other elements that has a high degree of contrast against the background color. For web content, the standard is 4.5:1 for most text. Avoid light text on light backgrounds and dark text on dark backgrounds.


Some of the automated accessiblity checkers will alert you to color errors as you work. To test on your own, try downloading a desktop tool, such as the TPGi's Color Contrast Analyser.

9. Avoid Using Color Alone to Convey Meaning

Avoid using color alone to convey meaning, as your message may be missed or misunderstood by individuals who can't see color. Instead use color along with a secondary element, (such as shape or text differences) to ensure the meaning can be understood without the use of color alone.

10. Review the Reading Order of Content on Each Slide

Verifying the reading order ensures that screen readers and assistive technology can read material in the order it is meant to be presented. Use the tab key on each slide to see content selected in the order that it will be read


  • PowerPoint: You can inspect and change the order on each slide using the ”Selection Pane” Tool. Slide Title should be at the bottom of the list.
  • Slides: You can reorder slide elements by right clicking on each and selecting "Order" and then sending elements backwards or forwards. Slide Title should be at the very "back"
