Change Slide Orientation
Share
By default, PowerPoint presentations use landscape orientation. But sometimes, portrait slides are a better choice — for example, when creating posters, mobile content, or documents. Luckily, you can change the slide orientation in just a few steps.
Step 1: Open the Design Tab
Go to the Design tab in the top menu to access layout options.

Step 2: Open Slide Size Options
On the right-hand side, click Slide Size and then choose Custom Slide Size.

Step 3: Choose Orientation
In the dialog box, select Portrait or Landscape under Slide Orientation. Then click OK to apply.

Step 4: Adjust Content Scaling
PowerPoint will ask if you want to Maximize the content or Ensure Fit. Choose the option that best preserves your layout.

Result: Slides in the Orientation You Need
Your presentation now uses the new orientation, making it fit perfectly for your specific use case.
💡 Pro Tip: Portrait orientation is great for posters, handouts, and mobile-optimized presentations. Combine it with custom slide sizes to fit exactly to your needs.
