Handouts are documents you can print from within PowerPoint that include slide representations from your presentation. PowerPoint lets you include as many as 9 slides on each Handout page. Of course, with 9 slides on a page, your slides will look more like thumbnails. You can also choose to print just one slide on every handout page, so then your Handout pages will look like individual slides printed on a page. Most Handouts are created to be printed, and the look and feel of these printed Handouts is determined by the Handout Master. To access and make edits to the Handout Master, you need to get to the Handout Master view in PowerPoint 2016 for Mac.
