How to Add Alternative Text (Alt. Text) to PowerPoint (Desktop Mac)


The best practice is to use sans-serif fonts, rather than serif or decorative fonts. Sans serif does not have decorative lines. The fonts would include Arial, Calibri, Century Gothic, Tahoma, and Verdana. The font size should be 24 pt. font for the body text. The font could be larger depending on the audience or page layout.

Open your PowerPoint.

Right-Click on image/icon.

The options from right-clicking on the location icon.

Select "Edit Alt. Text."

  1. Type in the information that is needed to understand the image/icon. Make sure it conveys the information needed for people to understand but do make it too long.
  2. Select if "Mark as decorative" if the image/icon is there only for decoration and dose not play an important role in the presentation.
