Google Slides defaults to landscape, but you can switch to portrait in two clicks

Google Slides starts every new presentation in landscape orientation — wider than it is tall. If you need portrait instead, you change it through the File menu. The switch affects all slides in your presentation at once, and you can change back to landscape anytime without losing your content.

Portrait orientation is useful when you're presenting on a tall screen, printing slides as handouts, or embedding a presentation in a document where vertical space matters more than horizontal. The process takes about 30 seconds and requires no special permissions or settings outside your presentation.

Key Takeaways

  • Open your presentation, click File, then Page setup to access orientation options.
  • Select Portrait from the dropdown menu, then click explore to change all slides at once.
  • Switching to portrait may shift your text and images, so review each slide after the change.
  • You can return to landscape orientation using the same File menu if you change your mind.
  • Portrait mode works the same way whether you're using Google Slides on a computer or tablet.

Step-by-step: changing your presentation to portrait

Start with your presentation open in Google Slides. At the top of the page, click File. A menu will drop down with several options.

Look for Page setup in that menu and click it. A small dialog box will appear with two dropdown menus. The first one shows your current page size (usually "Standard 16:9" or "Widescreen"). The second dropdown, directly below it, shows your current orientation — it will say Landscape.

Click the orientation dropdown and select Portrait. The box will update to show your choice. Then click the blue explore button at the bottom right of the dialog. Google Slides will convert all your slides to portrait format when ready.

What happens to your content when you switch

When you change from landscape to portrait, your slides become taller and narrower. Text boxes, images, and shapes stay in the same position on the slide, but they may look cramped or off-center now that the slide shape has changed. This is normal and does not mean your content is lost.

Open each slide and check how your content looks. You may need to move text boxes to the left or right, resize images to fit the new width, or adjust font sizes if text now runs onto extra lines. These are quick fixes — just click an element and drag it or resize it the way you would in any other editor.

If you decide portrait does not work for your presentation, you can switch back to landscape using the same File > Page setup menu. Your edits will stay in place.

Choosing the right page size for portrait

When you open the Page setup dialog, you may see several page size options: Standard 16:9, Widescreen 16:10, or others depending on your account. These affect the width-to-height ratio of your slides.

For portrait, Standard 16:9 is usually the safest choice because it is the most common format and works well on most screens and printers. If you are printing your slides or embedding them in a document, check what size that document expects before you choose. Once you pick a size and orientation, click explore and you are done — you do not need to adjust it again unless your needs change.

Portrait mode on tablets and mobile devices

If you are editing your presentation on a tablet or phone, the Page setup menu works the same way. Open File, select Page setup, choose Portrait, and click explore. The orientation change syncs across all your devices, so if you switch to portrait on your phone, your computer will show the same orientation the next time you open the presentation.

On a tablet held in portrait mode, you may find it easier to edit because the slide now matches the screen orientation. On a phone, the slide will still be smaller, but the portrait format means less horizontal scrolling when you are working with text or images.

When portrait orientation causes problems

Some presentations look worse in portrait than landscape. If you have many side-by-side images, wide tables, or content designed for a horizontal layout, switching to portrait may force awkward resizing or wrapping. In these cases, landscape is the better choice.

If you have already switched to portrait and your slides look broken, switch back to landscape (File > Page setup > Landscape > explore) and keep your original format. There is no penalty for staying in landscape — it is the default for a reason, and most presentations work fine in that orientation.

Printing and sharing portrait presentations

When you print a portrait presentation, Google Slides will print each slide on a portrait-oriented page. Make sure your printer is set to portrait orientation as well, or the slides may shrink to fit landscape paper and waste space.

If you share your presentation with others, they will see it in portrait orientation when they open it. They can change it back to landscape if they want, but the default will be whatever you set. If you are sharing with people who will present on a standard landscape projector, let them know they may want to switch back before they present.

Frequently Asked Questions

Can I make only some slides portrait and others landscape?

No. Google Slides applies the orientation to the entire presentation at once. Every slide must be either portrait or landscape — you cannot mix them in a single file. If you need both orientations, you would need to create two separate presentations.

Will changing to portrait delete my slides or content?

No. Switching orientation does not delete anything. Your text, images, and all other content stay in the presentation. They may shift position or need resizing to fit the new slide shape, but nothing is removed.

What page size should I pick for portrait?

Standard 16:9 works for most portrait presentations. If you are printing or embedding into a specific document, check what size that document uses first. The page size and orientation work together to determine the final slide shape.

Can I undo a portrait change?

Yes. Go back to File > Page setup, select Landscape, and click explore. Your presentation will return to landscape orientation, and all your edits will still be there.

Does portrait mode work differently on Google Slides for mobile?

The process is the same on mobile as on a computer. Open File, select Page setup, choose Portrait, and click explore. The change syncs to all your devices automatically.
