When you open a PowerPoint file, your slides are displayed horizontally by default. However, you can change them to vertical orientation with a few simple steps. Here's how to change your slides from a horizontal layout to a vertical layout.
Change slide orientation from landscape to portrait
First, open your PowerPoint file, in the Customize group of the Design tab , select Slide Size . Click Custom Slide Size ( Page Setup on Mac) in the drop-down menu.

The Slide Size dialog box appears. In the Slides group of the Orientation section , select Portrait or Landscape , and then click OK .

Use horizontal and vertical slides in the same PowerPoint file
Microsoft doesn't provide this feature, but if you link two PowerPoint files together, you can create the illusion that both portrait and landscape slides are on the same slideshow.
Note that when you create a link in PowerPoint , you will break the link if you move either file to a different location. To prevent this, move both files into the same folder before linking them.
In this example, we'll leave the first PowerPoint file in landscape layout and the second in portrait layout. Then open the first file and navigate to the file you want to link to. Select an object to use to insert the link. You can insert a link as text, an image, or an object.
Here we use text box.

When you click on this link, it will take you to the second file. In Slide Show view, it will appear that you are using both vertical and horizontal slides in the same slideshow.
However, if you want to return to the first file, you need to relink it to the second file.
Good luck!
