Create the Presentations
When you want to use slides in both landscape and portrait orientation, create two separate presentation files. Slides using the landscape orientation are in one PowerPoint presentation while the portrait orientation slides are in the second PowerPoint presentation. Then, link the two presentations together using action settings from one slide in the landscape presentation to the next slide you want (a portrait orientation slide), which is in the second presentation (and vice versa). The final slideshow flows perfectly and your audience won’t notice anything out of the ordinary when you click or mouse over a designated image or area to switch from one orientation to the other.
Link From Landscape to Portrait Orientation
To switch from the landscape presentation to the portrait orientation during your slideshow, select either a text object, a photo, or another graphic on the slide and follow the steps below. When this text or object is clicked during the slideshow, the portrait slide opens.
Link From Portrait to Landscape Orientation
Follow these same steps above to link back from the portrait slide to the next landscape slide. Then, repeat this process for any further instances when you need to change from a landscape slide to a portrait slide.
