For 8.5 x 11 inch (also known as Letter size) presentations, the recommended PowerPoint template size is set by default to this size in PowerPoint. However, if you need to manually adjust it, follow these simple steps:
- Open your PowerPoint program.
- Select the “Design” tab from the toolbar at the top.
- Click on the “Slide Size” button located in the “Customize” group on the far right side of the toolbar.
- Choose “Custom Slide Size” from the drop-down menu that appears.
- In the Slide Size dialog box that pops up, you can manually input the width and height dimensions. For an 8.5 x 11 inch presentation, input 8.5 inches for width and 11 inches for height.
- Click “OK” after you’ve input your dimensions. A dialogue box will appear asking how you’d like to scale the existing slides to the new size. Choose an option that best suits your needs.
Please remember that these dimensions are ideal for creating presentations intended to be printed or viewed as PDFs. If your presentation will be viewed on a screen or projected, a 16:9 aspect ratio is generally recommended for optimal viewing.
