Choose a Theme

PowerPoint has built-in themes and layout templates to help make creating presentations easier. Use these whenever possible, to help maintain consistency and properly structured content, so screen readers can better navigate the file.

Themes set the overall look of the entire presentation.

From the main ribbon, select Design.
Expand the Themes section by selecting the dropdown arrow.
Choose a theme. Keep in mind that pre-existing themes are not necessarily accessible. Themes that are clean and simple, with high contrast between text and background are best.

Use Slide Layouts

Each Theme has a variety of slide layouts. Layouts determine the look of individual slides within the presentation.

To add a slide to the presentation, from the Home tab, select New Slide, and choose a slide
To change the layout of an existing slide, select Layout, and choose a slide

Using pre-existing slide layouts preserves the reading order, which is important to screen readers. This is discussed in detail in the Check Reading Order section. Avoid adding elements unless absolutely necessary.

Also important for screen readers are slide titles. Slide titles should always be used but can be hidden. This is discussed in the Slide Titles section.

Using Slide Masters

Layouts have pre-set font and paragraph styles, but these can be modified. Rather than changing a style for each slide, a default can be set for the entire presentation by using the Slide Master. Default themes and styles allow for proper content structure and consistency.

From the main ribbon, select View.
Select Slide Master. Any change that is made within the master slide view will affect all slides that use that master.

On the master slide, highlight the text you would like to modify the style for.
Select the Home tab.

From here, you can change any of the Font attributes (such as font, color, and size) or Paragraph attributes (such as alignment, list structure, and line spacing).
- Line spacing is the amount of space between lines of text in a paragraph. Users with visual impairment or cognitive disabilities have trouble tracking lines of text that are too close together. If lines of text are spaced too far apart, they seem unrelated and can be difficult to read.
- Keep paragraph text lines at a spacing of 1.5.
- The space after a heading should be slightly less than the space above the heading. To change the spacing select line-spacing from the format menu then choose to add or remove space before or after the element.
Select Close Master View when finished

Pro Tip

If you like the styles you have set and want to reuse them in each new document you create, you can save them as your default templates.

From the Slide Master tab, choose Themes
Select Save Current Theme
Type the name of your template in the 'Export as' box. The Where field should direct you to the Themes folder.
Select Save.

Formatting Tips

Use 24pt type or larger for paragraph or bulleted text (headings should be larger)
Don’t use more than one font.
Use a font designed for the screen and available on most computers like Georgia, Verdana, Trebuchet, Arial, Calibri, Gill Sans, Corbel or Calisto MT.

Slide Titles

Each slide should have a unique title, as this helps assistive technology. However, you can choose to hide a title so it doesn’t show on the slide.

From the main ribbon, select the Home tab.
In the Arrange menu section, choose Selection pane. This displays all objects that are on a slide.

The eye icon next to the slide title will toggle visibility. Toggling off an unused title box allows assistive technology to detect a title for each slide, but keeps it hidden.

For multiple slides that have similar content, each title should be slightly different. For example, “Features of Campus (1 of 3)” or “Features of Campus (continued)”, etc. Having unique slide titles allows people using assistive technology to determine where they are in the presentation, and also allows them to skip from slide to slide.

Text Equivalents with Alt Text

All images in a PowerPoint presentation should have alternative text assigned. Alt text is a description that conveys the meaning or context of an image to a user who is not able to view the image directly.

Select an image in your document.
Select the Picture Format tab (this tab is hidden when the image is not selected)
Select Alt Text

Alternatively, if you do not see Alt Text, right select the image then choose Format Picture
Choose the Size and Properties tab, select Alt Text

Provide a full description in the description box. In the case of the SUNY Oswego logo you would write “State University of New York at Oswego.” If the image is more complex, like a chart, provide a title for the chart in the “title” box and a full description of the chart in the “description” box.
- If the image is purely decorative and adds no additional information to the slide, check the “Mark as decorative” box, or consider removing it.
- It is not recommended to use the “Generate a description for me” button. As the designer of the presentation, it is important to know why an image is included, and the alt attribute should reflect what the image is meant to convey to the audience.

Provide Contextual Hyperlinks

Hyperlinks in a digital document should be embedded within the text to aid in readability and accessibility. The linked text should concisely describe where the link goes and should be understood out of context. Do not use vague phrases such as “click here” or “read more.” Likewise, do not link using entire sentences.

Imagine you have the sentence “I work at SUNY Oswego” in your document and you want the words SUNY Oswego to link directly to the college’s website.

Highlight the text you want to convert to a hyperlink (in this example, SUNY Oswego).
Select the Insert tab
Select Link

You can link to external web pages or to a slide within the document.
- To link to an external page, choose Web Page or File, and include the full URL in the Address field (in this case, https://oswego.edu).

To link to another slide within the document, choose This Document, and select the slide you want to link to.

Select “OK.”

Creating Accessible Tables

From the main menu, select the Insert tab
Select Table. A drop-down table and menu will appear.
- Highlight the number of rows and columns you’d like in the table
- OR choose Insert Table from the menu below and enter in the appropriate number of rows and columns

Layout tables are not recommended. Tables should be used for tabular data. For a data table, be sure headers are defined:

Place the cursor inside the table. From the main menu, under the Table Tools section, choose Design.
- The Header Row and First Column boxes should be checked

Style formats can be used within tables:

Highlight the cell or row you wish to style
From the main menu, select the Home tab
In the Font and Paragraph sections, choose the appropriate formats

Check Reading Order

If elements are added to a slide layout, the order in which they are read by a screen reader should be verified. In the example picture below, the outlined image and text box were both added to the original slide layout. This triggers a “Check reading order” warning when the accessibility checker is run.

To verify or change the order elements are “seen” on a page:

From the main ribbon, select the Home tab
In the Arrange menu section, choose Selection pane. This displays all objects that are on a slide.

Objects will be read by assistive technology beginning with the bottom list item and ending with the top item.
Highlight an item name in the Selection panel to see which item in the slide it corresponds to. In this example, the added text box (textbox 8) is the first on the list to be read (because it’s at the bottom). This should be the last item to be read, so it needs to be moved to the top of the list.

To reorder items, use a mouse to drag them to the correct position within the list.
Alternatively, choose Reorder Objects from the Arrange menu section.

Use arrow keys or the mouse to move the elements to the proper order, with 4 being the first read, and 1 being the last read

By bringing Textbox 8 to the top of the list, the reading order would be as follows:
- Title 4 (“Check reading order!”)
- Content placeholder 6 (Green logo with cupola on side)
- Picture 7 (Black logo with cupola on top)
- Textbox 8 (“An image and a text box…”)

Run an accessibility check

PowerPoint has a built-in accessibility checker.

From the main ribbon, select the Review tab.
Choose Check Accessibility.

A sidebar will open up that will identify errors and warnings.
Highlight each error for guidance on how to resolve each issue.

Address each issue one at a time throughout the document.
Select the Check Accessibility button from the Review tab again when you have completed each task to receive an updated report.
Continue to revise until all checks have passed.

Converting PowerPoint Files

When you save/export a PowerPoint to another format, like a PDF, it is important to note that your document may not be fully accessible in the new format (even if the PowerPoint is). If you convert your document to a PDF, be sure to review and revise that document in Adobe Acrobat Pro with its built-in accessibility checker (See Acrobat Pro tutorial).
