Create Accessible PowerPoints


The following link will show you step by step how to create accessible PowerPoints: http://webaim.org/techniques/powerpoint/

In a nutshell however, all you really need to do is:
  1. Use the built in templates and slides layouts.Using these templates correctly will ensure that your files have correctly-structured headings and lists, proper reading order, etc. The correct use of slide layouts is probably the most significant thing you can do to ensure that your content is accessible.

  2. If you have decorative images in your presentation don't worry about alt text, but if you have images that support your content then you should set up an alt text for each. When you are using graphs or charts you especially want to use alt descriptions.
  3. Use tables sparingly in your presentation. In PowerPoint, you can style rows and columns so they appear as data tables, but there is no way to add the content 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.

  4. Use descriptive URL links.
  5. Other principles

    • Ensure that font size is sufficient. If your presentation will be viewed on a projector, font size may need to be even larger.
    • Provide sufficient contrast. If your presentation will be viewed on a projector, sometimes the contrast needs to be even more pronounced.
    • Do not use color as the only way to convey content.
    • Avoid automatic slide transitions.
    • Use simple slide transitions when possible. Complex transitions can be distracting.
    • Use simple language.
    • Check reading order of text boxes that are not part of the native slide layout. They are usually the last thing read by a screen reader.
    • If you have embedded video, ensure that the video is captioned, and that the player controls are accessible.
    • If you have embedded audio, ensure a transcript is included.
    • If your slides contain animations, ensure that they are brief and do not distract from the most important content on the page.

  6. Exporting your PPT to PDF? PDF is often the best format to display PowerPoint presentations on the web. The file size is relatively small, distracting slide transitions are removed, and everyone has a PDF reader. Most importantly, heading structure and other accessibility information will remain intact if you export the file correctly. If you have a presentation with tables, and if you know how to add additional accessibility information in Adobe Acrobat, it might be possible to create a PDF file that is more accessible than the original PPT file.
