Define Your PowerPoint Poster Size
When creating a poster in PowerPoint, the first thing you need to do is define its size.
Open PowerPoint. Choose an existing template or open a blank presentation. Select the Design tab, located near the upper-left corner of the PowerPoint interface. On a Mac, select File > Page Setup and enter a custom poster size. Select Slide Size > Custom Slide Size. In the Slide Size dialog box, select Portrait or Landscape, enter the width and height for your poster, then select OK. Common poster sizes (in inches) include 11x17, 18x24, 24x36, 27x41, 48x36 and 56x36. Your printer must support these sizes. A message asks if you want to maximize the size of the content or scale it down to ensure it will fit on the new slide. Select Ensure Fit. On a Mac, go to File > Page Setup > Options > Paper Size. Select Manage Custom Sizes, and then enter the page size for your poster. Select OK. In Page Setup, enter the width and height, then select Portrait or Landscape. You’ve successfully set your poster size.
Add Content to Your PowerPoint Poster
Back in the main PowerPoint interface, it’s time to create your poster content. You’ll use only one slide for a poster, so make sure all the content fits.
Creating content for a PowerPoint poster is essentially the same as creating content for a presentation slide. What you see is what you get. Take your time with details such as background and fonts as well as image and text placement, making sure your poster will stand out once it’s printed.
Print Your PowerPoint Poster
If you’ve defined the slide size and completed the design, it’s time to print your poster. Make sure you have the proper paper loaded and that the printer is online and seen by your computer.
To print a poster:
Go to File > Print. On a Mac, in the Print dialog box, check the print settings, select Scale to Fit Paper, and then select Print. Select Print Full Page Slides. Check the preview and settings, and then select Print.
