Overview
This digital accessibility learning guide introduces accessibility to PowerPoint presentations for people living with disabilities. PowerPoint presentations, from classrooms to business meetings, are widely used and should be accessible to all participants, including those using assistive technologies. This extensive guide will show you how to apply the basic accessibility requirements to PowerPoint presentations. This guide includes the following topics:
- Slide Layouts
- Slide Titles
- Lists
- Hyperlinks
- Tables, Charts, and Graphs
- Alternative Text
- Notes
- Reading Order
- Animations
- Video Captions
- Accessibility Testing
If you use keyboard-only navigation to make Microsoft PowerPoint presentations accessible, view the keyboard shortcuts for Microsoft PowerPoint.
Slide Layouts
Learn how to use and create slide layouts.
Definitions
- Slide: A single page is included in the presentation.
- Slide layouts: templates that include formatting, placement, and placeholder boxes for content.
- Placeholder: a container that holds different types of content, such as text, graphs, charts, images, videos, etc.
Things to keep in mind
PowerPoint provides some basic layouts by default. You can also create custom layouts. The slide master section describes custom layouts in detail.
Only add content to content placeholders. Do not insert text boxes because they are not accessible to assistive technologies. This will be discussed in detail in the outline view section.
Slide Titles
Make sure all your slides have unique titles. Without proper titles, the screen reader users will not know what the slide is about. Slide titles are headings in the presentation. If you have more than one slide for each topic, you can number the slides. This will tell the screen reader users that there is more than one slide for the topic.
For example,
Slide 1: Accessible PDF documents (1 of 3)
Slide 2: Accessible PDF documents (2 of 3)
Slide 3: Accessible PDF documents (3 of 3)
Slide 1: Accessible PDF documents (Continued 1 of 3)
Slide 2: Accessible PDF documents (Continued 2 of 3)
Slide 3: Accessible PDF documents (Continued 3 of 3)
Lists
Use lists to organize information. Use ordered lists where the order matters; otherwise, use unordered lists.
To use lists:
- Go to Home > Bullets (unordered list) or Home > Numbering (ordered list).
- Click on the little arrow button beside the lists to choose the type of symbols/numbers.
Hyperlinks
Hyperlinks are one of the most important pieces of information. Visit the accessible content page to learn how to write accessible hyperlinks. To add hyperlinks:
- Select the link text.
- Right-click the selected link text and select link.
- The following window will appear. Add the hyperlink text in the Text to display field and URL in the Address field.
When you add/paste a URL to the slide, PowerPoint automatically creates a link. If your presentation already includes links, here is how to edit the link text:
- Select the link text.
- Right-click on the link text, and select Edit link.
- Edit Text to Display. This will change the link text in your slide.
Tables, Charts, and Graphs
Alternative Text
This section includes a step-by-step process for adding alt text to images, charts, and graphs in PowerPoint. Alt text is crucial for screen reader users. Without it, users will not know what the image is about. Visit the accessible content page to learn how to write proper alt text.
Notes
You can add notes to each slide in a presentation. Keep in mind that the notes section is accessible to the screen readers. You can access the notes section at the very bottom of the slide.
People with dyslexia have a hard time reading excess information on the slide, so please make sure you limit the amount of text on the slide. Include important information on the slide, and add the in-depth information in the notes section.
Reading Order
The screen readers read the slides based on the reading order set in the presentation. It is essential to manually check the reading order of your slides and content to be sure it is logical. To do so:
- Go to Home > Select.
- Click on the dropdown by Select button and click on Selection Pane.
- A new panel will appear on the right side.
- The panel will show all the contents in the slide you are on. The reading order starts from bottom to top. So in the image above, the screen reader will read the content in the following order:
Picture 11 → Text Box 5 → Text Box 6 → Picture 1
Correct the reading order for all the slides if necessary, which is why it is beneficial to use slide layouts. You can modify the content’s reading order in the layouts so that when you use that layout, all the content will have the correct reading order.
Animations
Animations are sometimes used in presentations to add visual interest. However, it is a best practice to avoid animations. Keep in mind the following:
- Animations are ignored by the screen readers and can make content difficult to read
- Graphics sliding in from the left or right or bullets appearing one at a time are triggers for people living with some neurological conditions
- Flashing animations can cause seizures in people living with epilepsy. The number of flashes should not be greater than 3 in one second or should be avoided altogether.
- Avoid fast-moving animations for people living with vertigo.
- Animations can also be very confusing for people with cognitive disabilities
Video Captions
For more information on audio and video captions, see the video accessibility page. If your presentation includes a video, it is essential to add captions to each video and audio description augmentation. To do so,
- Select the video.
- Go to Video Tools > Playback > Insert Captions.
- Click on the Insert Caption button.
- It will open another window where you can browse for your caption file and insert the file.
You can also utilize the Notes section to add the audio transcript.
