Windows: Best practices for making PowerPoint presentations accessible

The following table includes key best practices for creating PowerPoint presentations that are accessible to people with disabilities.

What to fix	How to find it	Why fix it	How to fix it
Include alternative text with all visuals and tables. Visual content includes pictures, clip art, SmartArt graphics, shapes, groups, charts, embedded objects, ink, and videos.	To find missing alternative text, use the Accessibility Checker.	Alternative text helps people who can't see the screen to understand what's important in images and other visuals. Avoid using text in images as the sole method of conveying important information. If you must use an image with text in it, repeat that text in the document. In the alternative text, briefly describe the image and mention the existence of the text and its intent.	Review or edit automatically generated alt texts in photos Add alt text to images Add alt text to SmartArt graphics Add alt text to shapes Add alt text to charts Add alt text to tables
Make sure slide contents can be read in the order that you intend.	Use the Accessibility Checker to find slides that have possible problems with reading order.	When someone who can see reads a slide, they usually read things, such as text or a picture, in the order the elements appear on the slide. In contrast, a screen reader reads the elements of a slide in the order they were added to the slide, which might be very different from the order in which things appear. To make sure everyone reads the contents in the order you intend, it's important to check the reading order.	Set the reading order of slide contents
When creating a new slide, use the built-in slide designs.		PowerPoint contains built-in slide layouts that you can apply to any slide. When you use them with a new slide, these layouts automatically make sure that the reading order works for everyone.	Use built-in slide designs for inclusive reading order
Add meaningful hyperlink text and ScreenTips.	To determine whether hyperlink text makes sense as standalone information and whether it gives readers accurate information about the destination target, visually scan the slides in your presentation.	People who use screen readers sometimes scan a list of links. Links should convey clear and accurate information about the destination. For example, instead of linking to the text Click here, include the full title of the destination page. Tip: You can also add ScreenTips that appear when your cursor hovers over text or images that include a hyperlink.	Add hyperlink text and ScreenTips
Ensure that color is not the only means of conveying information.	To find instances of color-coding, visually scan the slides in your presentation.	People who are blind, have low vision, or are colorblind might miss out on the meaning conveyed by particular colors. For example, add an underline to color-coded hyperlink text so that people who are colorblind know that the text is linked even if they can't see the color. For headings, consider adding bold or using a larger font.	Use an accessible slide design
Use sufficient contrast for text and background colors.	To find insufficient color contrast, use the Accessibility Checker. You can also look for text in your spreadsheet that's hard to read or to distinguish from the background.	Use strong contrast between text and background, so people with low vision can see and use the content. Use dark text on a white or off-white background, or reverse it and use white text on a dark background. White and black schemes also make it easier for people who are colorblind to distinguish text and shapes.	Use accessible text color
Give every slide a unique title	To find slides that do not have titles, use the Accessibility Checker.	People who are blind, have low vision, or a reading disability rely on slide titles to navigate. For example, by skimming or using a screen reader, they can quickly scan through a list of slide titles and go right to the slide they want.	Use unique slide titles Hide a slide title
Use a simple table structure, and specify column header information.	To ensure that tables don't contain split cells, merged cells, nested tables, or completely blank rows or columns, use the Accessibility Checker.	Screen readers keep track of their location in a table by counting table cells. If a table is nested within another table or if a cell is merged or split, the screen reader loses count and can't provide helpful information about the table after that point. Blank cells in a table could also mislead someone using a screen reader into thinking that there is nothing more in the table. Screen readers also use header information to identify rows and columns.	Use table headers
Use a larger font size (18pt or larger), sans serif fonts, and sufficient white space.	To find potential issues related to fonts or white space, review your slides for areas that look crowded or illegible.	People who have dyslexia describe seeing text "swim together" on a page (the compressing of one line of text into the line below). They often see text merge or distort. For people who have dyslexia or have low vision, reduce the reading load. For example, they may benefit from familiar sans serif fonts, such as Arial or Calibri. Avoid using all capital letters and excessive italics or underlines. Include ample white space between sentences and paragraphs.	Use an accessible slide design Format text for accessibility
Make videos accessible to visually impaired and hearing-impaired users.		Subtitles typically contain a transcription (or translation) of the dialogue. Closed captions typically also describe audio cues such as music or sound effects that occur off-screen. Video description means audio-narrated descriptions of a video's key visual elements. These descriptions are inserted into natural pauses in the program's dialogue. Video description makes video more accessible to individuals who are blind or visually impaired.	Use captions, subtitles, and alternative audio tracks in videos

Add alt text to visuals and tables

The following procedures describe how to add alt text to visuals and tables in your PowerPoint presentations.

Note: We recommend only putting text in the description field and leaving the title blank. This will provide the best experience with most major screen readers including Narrator. For audio and video content, in addition to the alt text, include closed captioning for people who are deaf or have limited hearing.

Review or edit automatically generated alt texts in photos

PowerPoint for PC in Office 365 automatically generates alt texts for photos by using intelligent services in the cloud. You can review and edit the autogenerated alt texts.

Note: This feature is only available to Office 365 subscribers who have joined the Office Insider program. If you are an Office 365 subscriber, make sure you have the latest version of Office.

Use accessible text color

Here are some ideas to consider:

• Use the pre-designed Office Themes to make sure that your slide design is accessible. For instructions, see Use an accessible slide design.

• Use the Accessibility Checker to analyze the presentation and find insufficient color contrast. It checks the text in the slides against the following elements:

  • Page color

  • Cell backgrounds

  • Highlights

  • Text box fill

  • Paragraph shading

  • SmartArt fills

  • Headers and footers

  • Links

Make slides accessible

The following procedures describe how to make the slides in your PowerPoint presentations accessible.

Use unique slide titles

1. To restore all placeholders for the selected slide, on the Home tab, in the Slides group, select Reset.

Make a title invisible on the slide, but still voiced by screen readers.

1. On the Home tab, in the Drawing group, select Arrange.

2. In the Arrange menu, select Selection Pane.

3. In the Selection pane, locate the Title text box, and then click the eye icon next to it.

Set the reading order of slide contents

Use the Selection pane to set the order in which the screen readers read the slide contents. The Selection pane lists the objects on the slide in reverse order. When the screen reader reads this slide, it reads the objects in the reverse order listed in the Selection pane.

1. On the Home tab, in the Drawing group, select Arrange.

2. In the Arrange menu, select Selection Pane.

3. In the Selection pane, to change the reading order, do one of the following:

   • Drag and drop items to the new location.

   • Select the item and then select the Up arrow button (Bring Forward) or Down arrow button (Send Backward).

Use built-in slide designs for inclusive reading order

PowerPoint has built-in slide designs that contain placeholders for text, videos, pictures, clip art, and more. They also contain all the formatting, such as theme colors, fonts, and effects. To make sure that your slides are accessible, the built-in layouts are designed so that the reading order is the same for people who see and people who use technology such as screen readers.

1. On the View tab, click Normal.

2. In the Thumbnail pane, locate the place where you want to add the new slide. Right-click, and select New Slide. Click the new slide to select it.

3. On the Design tab, expand the Themes gallery, and select the slide layout that you want. PowerPoint automatically applies this layout to the new slide.

4. Go to the new slide, and add the title and content that you want.

Use captions, subtitles, and alternative audio tracks in videos

PowerPoint 2016 supports the playback of video with multiple audio tracks. It also supports closed captions and subtitles that are embedded in video files.

Currently, only PowerPoint for Windows supports insertion and playback of closed captions or subtitles that are stored in files separate from the video. For all other editions of PowerPoint (such as PowerPoint for Mac or the mobile editions), closed captions or subtitles must be encoded into the video before they are inserted into PowerPoint.

Supported video formats for captions and subtitles vary depending on the operating system that you're using. Each operating system has settings to adjust how the closed captions or subtitles are displayed.

Closed captions, subtitles, and alternate audio tracks are not preserved when you use the Compress Media or Optimize Media Compatibility features. Also, when turning your presentation into a video, closed captions, subtitles, or alternate audio tracks in the embedded videos are not included in the video that is saved.

When you use the Save Media as command on a selected video, closed captions, subtitles, and multiple audio tracks embedded in the video are preserved in the video file that is saved.

To make your PowerPoint presentations with videos accessible, ensure the following:

• Videos include an audio track with video descriptions, if needed, for users that are blind or visually impaired.

• Videos that include dialogue also include closed captions or subtitles in a supported format for users that are deaf or hard of hearing.

In alt text, briefly describe the image and mention the existence of the text and its intent.	Add alt text to images Add alt text to shapes Add alt text to tables
Ensure that color is not the only means of conveying information.	People who are blind, have low vision, or are colorblind might miss out on the meaning conveyed by particular colors. For example, add an underline to color-coded hyperlink text so that people who are colorblind know that the text is linked even if they can't see the color. For headings, consider adding bold or using a larger font.	Use an accessible slide design
Use sufficient contrast for text and background colors.	The text in your presentations should be readable in High Contrast mode so that everyone, including people with visual disabilities, can see it well. For example, use bright colors or high-contrast color schemes on opposite ends of the color spectrum. White and black schemes make it easier for people who are colorblind to distinguish text and shapes.	Use an accessible slide design
Use a simple table structure, and specify column header information.	Screen readers keep track of their location in a table by counting table cells. If a table is nested within another table or if a cell is merged or split, the screen reader loses count and can't provide helpful information about the table after that point. Blank cells in a table could also mislead someone using a screen reader into thinking that there is nothing more in the table. Screen readers also use header information to identify rows and columns.	Use table headers
Use a larger font size (18pt or larger), sans serif fonts, and sufficient white space.	People who have dyslexia describe seeing text "swim together" on a page (the compressing of one line of text into the line below). They often see text merge or distort. For people who have dyslexia or have low vision, reduce the reading load. For example, they may benefit from familiar sans serif fonts, such as Arial or Calibri. Avoid using all capital letters, and excessive italics or underlines. Include ample white space between sentences and paragraphs.	Use an accessible slide design Format text for accessibility
Make videos accessible to visually impaired and hearing-impaired users	Subtitles typically contain a transcription (or translation) of the dialogue. Closed captions typically also describe audio cues such as music or sound effects that occur off-screen. Video description means audio-narrated descriptions of a video's key visual elements. These descriptions are inserted into natural pauses in the program's dialogue. Video description makes video more accessible to individuals who are blind or visually impaired.	Use captions, subtitles, and alternative audio tracks in videos

Office Online: Best practices for making PowerPoint Online presentations accessible

The following table includes key best practices for creating PowerPoint Online presentations that are accessible to people with disabilities.

What to fix	How to find it	Why fix it	How to fix it
Include alternative text with all visuals and tables. Visual content includes pictures, clip art, SmartArt graphics, shapes, groups, embedded objects, and videos.	To find missing alternative text, use the Use the Accessibility Checker in PowerPoint Online.	Alternative text helps people who can't see the screen to understand what's important in images and other visuals. Avoid using text in images as the sole method of conveying important information. If you must use an image with text in it, repeat that text in the document. In the alt text, briefly describe the image and mention the existence of the text and its intent.	Add alt text to images Add alt text to SmartArt graphics Add alt text to shapes or embedded videos Add alt text to tables
Add meaningful hyperlink text.	To determine whether hyperlink text makes sense as standalone information and whether it gives readers accurate information about the destination target, visually scan the slides in your presentation.	People who use screen readers sometimes scan a list of links. Links should convey clear and accurate information about the destination. For example, instead of linking to the text Click here, include the full title of the destination page.	Add hyperlink text Change the text of a hyperlink
Ensure that color is not the only means of conveying information.	To find instances of color-coding, visually scan the slides in your presentation.	People who are blind, have low vision, or are colorblind might miss out on the meaning conveyed by particular colors. For example, add an underline to color-coded hyperlink text so that people who are colorblind know that the text is linked even if they can't see the color. For headings, consider adding bold or using a larger font. Circle or use animation to highlight information, rather than relying on laser pointers or color. Add shapes if color is used to indicate status. For example, add a checkmark symbol if green is used to indicate "pass" and an uppercase X if red indicates "fail".	Format text for accessibility
Use sufficient contrast for text and background colors.	To find insufficient color contrast, look for slide text that's hard to read or to distinguish from the background.	The text in your presentations should be readable so that everyone, including people with visual disabilities, can see it well. For example, use bright colors or high-contrast color schemes on opposite ends of the color spectrum. White and black schemes make it easier for people who are colorblind to distinguish text and shapes. Avoid using orange, red, and green in your template and text. Use patterns in graphs, instead of color, to highlight points of interest.	Use an accessible slide design
Give every slide a unique title.	Use the Accessibility Checker in PowerPoint Online to find slides that don't have titles.	People who use screen readers and other assistive technology hear slide text, shapes, and content read back in a specific order. That's why it's a good practice to use the slide layouts in PowerPoint Online, which ensure that content is read in a logical order by screen readers. People who are blind, have low vision, or a reading disability rely on slide titles to navigate. For example, by skimming or using a screen reader, they can quickly scan through a list of slide titles and go right to the slide they want.	Use a logical reading order Use unique slide titles
Use a simple table structure, and specify column header information.	To ensure that tables don't contain split cells, merged cells, nested tables, or completely blank rows or columns, Use the Accessibility Checker in PowerPoint Online.	Screen readers keep track of their location in a table by counting table cells. If a table is nested within another table or if a cell is merged or split, the screen reader loses count and can't provide helpful information about the table after that point. Blank rows and columns in a table could also mislead someone using a screen reader into thinking that there is nothing more in the table. Screen readers also use header information to identify rows and columns.	Use table headers
Use a larger font size (18pt or larger), sans serif fonts, and sufficient white space.	To find potential issues related to fonts or white space, review your slides for areas that look crowded or illegible.	People who have dyslexia describe seeing text "swim together" on a page (the compressing of one line of text into the line below). They often see text merge or distort. For people who have dyslexia or have low vision, reduce the reading load. For example, they may benefit from familiar sans serif fonts, such as Arial or Calibri. Avoid using all capital letters and excessive italics or underlines. Include ample white space between sentences and paragraphs.	Use an accessible slide design Format text for accessibility

Add alt text to images and tables

The following procedures describe how to add alt text to images and tables in your PowerPoint Online presentations.

4. In the title placeholder, type a unique name.

Note: A title doesn't necessarily have to be visible to be accessible. For example, people who use screen readers hear a slide's title even if it isn't visible. In the PowerPoint 2016 desktop version, you can use the Selection pane to turn visibility on or off for titles and other objects on a slide.

Use the Accessibility Checker in PowerPoint Online

1. Select the Review tab.

2. Select Check Accessibility.
