When creating presentations, the size of your PowerPoint slides can significantly impact the overall look and feel. Understanding the standard PowerPoint slide size in centimeters can help you design slides that are both visually appealing and functional. Let's dive into the details, including the standard slide size, custom sizes, and how to change the slide size in PowerPoint.
Standard PowerPoint Slide Size in CM
The standard PowerPoint slide size is 13.33 cm (width) by 7.5 cm (height), which corresponds to the 4:3 aspect ratio. This size is suitable for most presentations and is the default setting in PowerPoint. However, depending on your presentation's purpose and the venue, you might need to adjust the slide size.
Common Slide Sizes in CM
- 4:3 (Standard): 13.33 cm x 7.5 cm
- 16:9 (Widescreen): 19 cm x 10.8 cm
- 3:2 (A4): 16.51 cm x 11.08 cm
These sizes are commonly used in presentations, but you can also create custom sizes to fit specific needs.

Changing Slide Size in PowerPoint
PowerPoint allows you to change the slide size easily. Here's how to do it in both PowerPoint 2016 and PowerPoint Online:
PowerPoint 2016
- Click on the "Design" tab in the ribbon.
- In the "Slide Size" group, click on the drop-down arrow next to the current slide size.
- Select the desired slide size or choose "Custom" to create a new size.
PowerPoint Online
- Click on the "Design" tab in the ribbon.
- In the "Slide Size" group, click on the drop-down arrow next to the current slide size.
- Select the desired slide size or choose "Custom" to create a new size.
Changing the slide size will not affect the content of your slides; it will only change the size of the slide itself. However, keep in mind that changing the slide size might require you to adjust the placement and size of your content.
Slide Size and Aspect Ratio
The aspect ratio of your slides is crucial, as it determines how your content will be displayed. The most common aspect ratios are 4:3 (standard) and 16:9 (widescreen). When choosing a slide size, ensure that the aspect ratio fits the venue's screen resolution to avoid distorted or cut-off content.

Slide Size and Content
Changing the slide size can significantly impact your presentation's content. For instance, a widescreen (16:9) slide size provides more horizontal space, making it ideal for displaying wide images or comparing data side by side. On the other hand, a standard (4:3) slide size is better suited for text-heavy slides or when using a projector with a 4:3 aspect ratio.
When designing your slides, consider the content you'll be presenting and choose a slide size that complements it. Don't be afraid to experiment with different sizes and aspect ratios to find the best fit for your presentation.
Slide Size and Printing
When printing your PowerPoint slides, the slide size can affect the number of slides that fit on a page and the overall layout. For example, using a 3:2 (A4) slide size ensures that your slides will print correctly on A4 paper without any cropping or resizing. However, using a different slide size might require you to adjust the print settings or use a custom page setup.

Understanding the standard PowerPoint slide size in centimeters and how to change it can help you create more effective and visually appealing presentations. By considering the slide size, aspect ratio, and content, you can design slides that engage your audience and communicate your message clearly.
