## About slide sizes in PowerPoint

Before you change the [size of your slides in PowerPoint](https://plusai.com/blog/powerpoint-slide-size-and-dimensions), here are a few points to keep in mind.

-   Slide size applies to all slides in a presentation. You cannot change the size of individual slides.
-   Orientation applies to all slides in a presentation. You cannot use different orientations in a single slideshow.
-   Currently, there is no setting for the default slide size for new presentations. If you want a default size, you must create and save a custom PowerPoint theme.

## Method 1: Change from widescreen to standard

One of the quickest ways to change the slide size in PowerPoint is to switch from the default widescreen to the standard size.

Widescreen is a 16:9 ratio which is suitable for modern TV screens and widescreen monitors. Standard is a 4:3 ratio which is more of a square shape. If the screen you’re using to present your slideshow uses a 4:3 ratio, you can make the slide size switch easily in PowerPoint.

Go to the **Design** tab, open the **Slide Size** menu in the Customize section, and choose **Standard**.

If you already have content on your slides, you’ll see a message asking how you’d like to scale that content for the smaller slide size. Choose **Maximize** or **Ensure Fit** on Windows or **Scale** or **Don’t Scale** on Mac.

You’ll see your slides update to accommodate the new size; however, you may need to adjust, move, or even resize slide elements depending on your previous selection.

## Method 2: Select a preset slide size

Maybe neither widescreen nor standard are the right size for your presentation. You can select a preset slide size in PowerPoint to accommodate things like a banner, letter or legal paper size, or 35mm slides.

1.  Go to the **Design** tab, open the **Slide Size** menu, and choose **Custom Slide Size** on Windows or **Page Setup** on Mac.

2.  In the **Slide sized for** drop-down menu, select the size you want to use.

3.  Optionally, you can [change the orientation for the slides](https://plusai.com/blog/how-to-make-google-slides-vertical) along with that for notes, handouts, and outlines.

4.  If prompted, choose how to scale the slide content as described above and click **OK** when you finish.

## Method 3: Use a custom slide size

If none of the above options provide you with the size you need for your slides, you can enter custom dimensions.

1.  Go to the **Design** tab, open the **Slide Size** menu, and choose **Custom Slide Size** or **Page Setup**.
2.  In the **Slide sized for** drop-down menu, select **Custom**.

3.  Enter the dimensions in the **Width** and **Height** boxes or use the arrows to move up or down in small increments and optionally, adjust the orientation.

4.  If prompted, choose how to scale the content and click **OK** to see the custom slide size.
