On the Design tab, click the More arrow in the bottom-right corner of the Themes group: (If you want a different default slide size than what's listed there, select Custom Slide Size and then choose your size in the Slide Size dialog box, and then click OK.) Then on the Design tab, click Slide Size and choose the size you want for a default. Then double-click the Blank Presentation to create a new, empty presentation. On the File tab of the toolbar ribbon, select New. This version of PowerPoint has a default size of 16:9 for new presentation, but you can create a different default for yourself. You can change the unit of measure that is shown in PowerPoint dialog boxes if you like. PowerPoint then converts measurements, if necessary, to the type of unit your operating system uses. Type a number followed by a space and then the appropriate abbreviation: in, cm, or px. In the Height and Width boxes, PowerPoint accepts measurements in inches, centimeters, or pixels.

In the Slide Size dialog box, ensure the orientation is set the way you want it. There are two options for 16:9 aspect ratios: Overhead provides an aspect ratio very close to the standard 4:3 slide size. In the Slide Size box, click the down arrow next to Slides sized for and select an option. Select Slide Size, and then select Custom Slide Size. See the section below named 'Make a default size to start from when creating new presentations.'

However, you can make it easy to create a new 4:3 presentation for yourself whenever you want-by defining a custom theme that uses the 4:3 aspect ratio. When you change the slide size for a presentation, the size you choose only applies to that presentation. The 16:9 widescreen setting is the default value for new presentations you create. This could make your content appear smaller, but you’ll be able to see all content on your slide. Choosing this option could result in your content not fitting on the slide.Įnsure Fit: Select this option to decrease the size of your content when scaling to a smaller slide size. Maximize: Select this option to increase the size of your slide content when you are scaling to a larger slide size. When PowerPoint is unable to automatically scale your content, it prompts you with two options: Select Slide Size, and then select either Standard (4:3) or Widescreen (16:9). On the Design tab of the Ribbon, locate Slide Size in the Customize group, near the far right end of the toolbar.
