We all prepare presentation in default slide size, but sometime we need to change the slide size and orientation, like portrait, landscape and custom slide size, so in this post I will show you how to change slide orientation and size..
1. Open the Microsoft PowerPoint file click on “Design” and extend the “Slide size” choose “Custom slide size”
2. Here you can easily change slide orientation like portrait, landscape, slide size, or you can give required slide width and height.
