PowerPoint: Resize a Presentation for Different Screens

The computer screen you use to create a PowerPoint presentation may be different than the screen from which you present the PowerPoint. The aspect ratio may be different between the two computers.

What is Aspect Ratio?

Aspect ratio is the size relationship between the height and width of the slides. Some ratios resemble a square while others resemble a rectangle. The three aspect ratios used on Cedarville's campus are 4:3, 16:9, and 16:10. Click the Printable Instructions below for a table of the various aspect ratios used on campus.


If there are issues with the aspect ratio, it may move the elements of your slide. You may want to arrive at the presentation room at least 10 minutes early to test your PowerPoint. 

Creating Your Presentation in the Proper Aspect Ratio

  1. Click the [Printable Instructions] button below to check the aspect ratio (4:3, 16:9, or 16:10) of the Cedarville room you will be presenting in.
  2. In PowerPoint, click the [Design] tab.
  3. From the "Customize" group, click [Slide Size]. 
  4. From the dropdown menu, select the proper aspect ratio for the room you will be presenting in, or click "Custom Slide Size" to manually enter the aspect ratio.


When you preview your presentation on your computer, the slide may not take up the whole screen.
