Using slide layouts provided within PowerPoint will ensure files have correctly structured headings and lists, and proper reading order.
Creating Slide Layouts
1. Select Home> New Slide.
2. Choose the desired layout from the Layout option.
Alternative Text for Images
Images can be given appropriate alternative text in PowerPoint. This alt text is read by a screen reader in a PowerPoint file and should remain intact when exporting to HTML or PDF.
Adding Alt Text
Right-click on the image and choose Format Picture.
Select the Size & Properties icon and choose Alt Text.
Enter appropriate alt text only in the Description field (not the Title field).
Accessible tables need a clear table structure and table headers to help guide a screen reader user.
• Select the Insert tab on the ribbon, then select Table > Insert Table.
• PowerPoint can style rows and columns so they appear as data tables, but there is no way to add table header information in a way that will be
identified by a screen reader.
• If your presentation contains more than the simplest tables, and if you have Adobe Acrobat, consider saving your presentation to PDF and adding
the additional accessibility information in Acrobat Pro.
PowerPoint automatically creates a hyperlink when a user pastes a full URL onto a page. These may not make sense to screen reader users, so more information is needed.
1. Select a hyperlink, right click, and select Edit Hyperlink or CTRL + k.
2. Change the text in the Text to Display field to a more meaningful description.
Outline and Notes Panels
PowerPoint contains two panels that can be used to enhance accessibility: the Outline panel and the Notes panel.
• The Outline panel, found under View> Outline View, contains a text outline of the content that appears in your slides.
• Reviewing this panel can help ensure the content on the slides is logically sequenced, that slide titles are unique and meaningful, and that reading
order is appropriate for any user.
• The Notes panel, found under View> Notes, allows the speaker to add notes and information that will not appear on the slides. This
information may not be accessed by a screen reader, so do not put important information in this area.
PowerPoint includes an accessibility resource that identifies accessibility issues.
Select File> Info.
Select the Check for Issues button and choose Check Accessibility.
The Accessibility Checker task pane will show accessibility errors, warnings, and tips on how to repair the errors. Select specific issues to see Additional Information at the bottom of the task pane.
