How do you change the orientation of your slides to landscape?

Changing the orientation of slides to landscape in PowerPoint is done through the Design tab, specifically by selecting Slide Size and then choosing Custom Slide Size. This method allows users to have precise control over the layout of their presentation. When you do this, you can select between standard orientations such as Portrait and Landscape, with Landscape being wider than it is tall, making it more suitable for presentations that utilize wider visuals or graphics.

The options available in the other choices do not lead to changing the slide orientation effectively. For instance, the Home tab mainly focuses on formatting text and objects rather than slide layout. The View tab is designed for different modes of viewing presentations, and the File tab's Print Setup pertains to print settings rather than the orientation of slides in the actual presentation. Therefore, the correct process to achieve a landscape orientation requires navigating through the Design tab to adjust the slide size.
