The fastest way: use Google Fonts, which are built in
Google Slides comes with about 20 fonts already loaded, and you can add hundreds more without leaving the app. The fonts Google provides are called Google Fonts — they're free, they work on every device, and they won't break your presentation if someone opens it on their phone or shares it with a colleague.
To add a Google Font, click on the text you want to change. Then click the font dropdown menu (it usually says "Arial" or whatever font is currently selected). Scroll to the bottom of the list and click "More fonts". A window will open showing hundreds of options. Type the name of the font you want, or scroll through the categories. Click the font name, then click "OK". It's now added to your presentation and to your personal font list for future slides.
This method works because Google Fonts live on Google's servers. When someone opens your presentation, their device downloads the font automatically. You don't have to install anything on your computer, and the font will look the same whether you're viewing it on a laptop, tablet, or phone.
Key Takeaways
- Google Fonts are built into Google Slides and work on every device without installation.
- To add a Google Font, select text, click the font dropdown, scroll to "More fonts", search or browse, and click OK.
- Fonts you add appear in your personal font list at the top of the dropdown for future use in that presentation.
- Custom fonts from your computer (like fonts you bought or downloaded) will not display correctly unless everyone viewing the presentation has that font installed.
- If you use a non-Google font and someone without it opens your presentation, Google Slides will substitute a similar font automatically, which may change your layout.
Why Google Fonts are safer than fonts on your computer
You might have fonts installed on your own computer that you love — fonts you bought, or downloaded from a design site. If you use one of those fonts in Google Slides, here's what happens: the font looks right on your screen because your computer has it. But when a colleague opens the same presentation, their computer doesn't have that font, so Google Slides picks a replacement automatically. The text might be wider, narrower, or a different weight, which can throw off your whole layout.
Google Fonts avoid this problem because they're hosted on Google's servers, not on your computer. When anyone opens your presentation, their device fetches the font from Google at the same time it loads the slide. Everyone sees the same thing.
The trade-off is choice: Google Fonts has hundreds of options, but not every font in the world. If you need a very specific typeface that isn't in Google Fonts, you have two options: use a Google Font that's close enough, or use your custom font and accept that it might look different on other people's screens.
How to find the right Google Font for your presentation
When you click "More fonts", the window shows fonts in categories: serif, sans-serif, display, handwriting, and monospace. If you're not sure what you're looking for, start with the category that matches your presentation's tone. Sans-serif fonts (like Roboto or Open Sans) are clean and modern, good for business presentations. Serif fonts (like Lora or Playfair Display) feel more traditional. Display fonts are bold and decorative, meant to grab attention.
You can also search by name if you already know what you want. Type a few letters and the list narrows down. As you click each font, you'll see a preview of how it looks. Pay attention to how it looks at the size you'll actually use it — a font that's beautiful at 48 points might be hard to read at 12 points.
Once you click OK, the font is added to your presentation. It also appears at the very top of your font dropdown menu from then on, so you don't have to search for it again in that presentation. If you want to use it in a different presentation, you'll search for it again — Google Fonts remembers your choices within a single presentation, not across all your presentations.
Changing fonts for a whole slide or all slides at once
If you want to change the font on multiple slides, you don't have to do it one text box at a time. Click on a text box, then use Ctrl+A (or Cmd+A on Mac) to select all the text in that box. Change the font. Now that font is applied to that text box only.
To change the font across your entire presentation, you need to edit the theme. Click the "Slide" menu at the top, then "Change theme". A panel opens on the right showing theme options. Click on the theme you're currently using (it will have a checkmark), then click the three dots next to it and select "Customize theme". A new window opens. Click on the font dropdown at the top. Choose your new font, and it will explore to all text in that theme — headings, body text, and everything else. Click "Done" and "explore".
Changing the theme font is the cleanest way to make a big change across many slides, because it respects the hierarchy of your presentation — headings stay as headings, body text stays as body text, they just use your new font.
What happens if you share a presentation with a custom font
If you accidentally use a font that isn't a Google Font — maybe you dragged and dropped a font file, or you're working on a presentation someone else created — Google Slides will try to substitute it. The substitution is usually a font that looks similar in weight and style, but it won't be exact.
The best way to catch this before you share is to open your presentation in a private browsing window or ask a colleague to open it on their device. If the text looks wrong, go back and change it to a Google Font. If you're sharing a presentation with someone and they tell you the fonts look different, ask them what they see, then switch to a Google Font and re-share the file.
You can also read your presentation as a PDF or as images if you need the fonts to look exactly the same on every device. When you read as PDF, Google Slides embeds the fonts in the file, so the presentation will look identical no matter who opens it. This is useful if you're printing slides or sending them to someone who won't be editing them.
Using fonts from outside Google Fonts
Google Slides doesn't let you upload custom fonts the way some design tools do. If you have a font file on your computer and you want to use it in Google Slides, you have a few workarounds, but none are straightforward.
One option is to convert your presentation to a PDF or image format, which embeds the fonts. Another is to use a tool like Canva or Adobe Express to design your slides with your custom font, then export them as images and insert those images into Google Slides as placeholders. This works if you're not planning to edit the text later.
The most practical approach for most people is to browse Google Fonts, find something close to what you want, and use that instead. Google Fonts has grown to include thousands of typefaces, including many that mimic popular paid fonts. Spending 10 minutes finding a Google Font that works usually saves you the headache of font substitution later.
Frequently Asked Questions
Can I use a font I downloaded from the internet?
Not directly in Google Slides. If you install a font on your computer and use it in a presentation, it will only display correctly on devices that have that font installed. For anyone else viewing the presentation, Google Slides will substitute a different font. Use Google Fonts instead to may support consistency across all devices.
Will my fonts look the same on mobile as they do on my computer?
Yes, if you use Google Fonts. Google Fonts are designed to render consistently across devices. If you use a custom font from your computer, it may look different or be substituted on mobile devices, depending on whether the viewer's phone has that font installed.
How do I remove a font from my font list?
Click the font dropdown, find the font you want to remove, and hover over it. A small X will appear. Click it to remove the font from your personal list for that presentation. The font will still be available in "More fonts" if you want to add it back later.
What if I want to use the same custom fonts in all my presentations?
Google Slides doesn't sync custom fonts across presentations. Your best option is to stick with Google Fonts, which are available in every presentation you create. If you need a specific look across multiple presentations, choose Google Fonts that match your brand and use them consistently.
Can I make a font bigger or smaller after I add it?
Yes. Adding a font to your presentation doesn't lock the size. Select the text and use the font size dropdown (usually showing a number like 18 or 24) to change how large or small it appears. The font itself stays the same; only the size changes.
