How to Choose the Perfect PowerPoint Slide Size for Your Presentation

What is the aim of your PowerPoint presentation?

Before you select your custom slide size, consider what you are trying to achieve. PowerPoint presentations are used for many different situations, and each of these situations will impact the PowerPoint slide sizes that you should consider.

Be sure that the ppt slide size fits the content rather than the content fitting the ppt slide size.

Have you added images or infographics?

Another factor you need to consider when selecting your PowerPoint slide sizes is whether you need to include space for particular images.

You might think that having your slides sized correctly is easy if you do it to a blank presentation. However, if you use unique imagery or infographics, common PowerPoint slide sizes might not do the job.

Factor in your use of imagery or infographics within your PowerPoint presentation slides before committing to a slide size.

What do you want your audience to focus on?

Finally, consider the most important aspects of your PowerPoint slides that you want your audience to read and understand. This factor will greatly impact what the PowerPoint slide size should be.

PowerPoint presentations all have different focal points, so it is important that the slide sizes you opt for meet the needs of your presentation.

How to Change The Size of a Slide in Microsoft PowerPoint

To start, open the PowerPoint presentation you would like to amend or set up a new presentation. Once you have opened your PowerPoint presentation, head to the Design tab located on the ribbon. You will see the Slide Size button within the Customize section from the design tab.

Once you are in the design tab, you can change the slide size for your presentation.

If you have Microsoft PowerPoint open in a window that is smaller than full screen, you might not be able to see this option to amend slide dimensions.

If you can't spot this button, select Customize from the design tab to show it, and then select Slide Size.

Once you have selected the Slide Size button, three options will appear in the slide size dialog box.

  • Widescreen (16:9) - select this option if you know your presentation will be on a wider TV screen, and your page setup needs to reflect that.
  • Custom slide size - Choose custom slide size to create your unique page setup

The Slide Size pop-up window will appear if you choose the final option. From here, you can select a custom slide size to work on or edit other slide size aspects, such as portrait to landscape.

When it comes to altering the PowerPoint slide size on a Mac, the options are extremely similar to Windows.

Head to the Design tab, and select the slide size option located on the right.

Click on the PowerPoint Slide Size button, and a drop-down menu will appear with three options for you to choose from.

The first two options in the design tab will not differ from changing the PowerPoint slide sizes in Windows, but instead of Custom Slide Size, the third option on Mac is named Page Setup.

Page Setup works the same way as Custom Slide Size, so click on that option from the drop-down menu.

When you have chosen the PowerPoint slide dimensions, you would like, select OK. A new Page Setup dialog box will appear, asking you how you want to handle your existing content.

Select either Scale or Don't Scale from the new Page Setup dialog box, select either Scale or don't Scale, depending on whether you want your current content to be changed to fit your new custom slide size.
