Instructions in this article apply to PowerPoint 2019, 2016, 2013, 2010; PowerPoint for Microsoft 365, and PowerPoint for Mac. View Two Presentations at One Time Stack the windows so that you can view each presentation without flipping back and forth. Open two presentations. Go to View. Select Arrange All. PowerPoint stacks both presentations side by side. Flip among slides to compare them individually. To copy slides between the two open presentations, change the view in both arranged presentations to Slide Sorter view. To copy slides, drag selected slides from one presentation to the other. The Arrange All option provides the best results if you use two presentations. If you want to arrange more than two presentations, you will need a much larger display to benefit.
