How to Change Slide Size for an Apple Keynote Presentation

  • MORE

Apple Keynote presentations default to the 4:3 aspect ratio, but that's not always the size you need. Not all displays have the same resolution, so it's good to know how to resize slides.

Here's how to change slide size in Keynote:

1. Click Document in the top right corner.screenshot 2016 07 20 13.57.19

2. Click Standard.screenshot 2016 07 20 13.58.11

3. Choose Widescreen or Custom Size. If you select the latter, you'll be given the options to name custom height and width in pixels.screenshot 2016 07 20 13.58.37

You've changed the size of your presentation slides. Since Keynote didn't automatically adjust content to fit (which PowerPoint does), it's time to resize content.
