You can use custom fonts in PowerPoint by installing them on your computer first, then selecting them from PowerPoint's font menu
PowerPoint pulls fonts from your operating system, not from the internet. This means you need to install a font file on your computer before PowerPoint can see it. Once installed, the font appears in PowerPoint's font dropdown alongside the fonts that came with your system. The process takes about two minutes and works the same way whether you're on Windows or Mac.
The fonts you install stay on your computer. If you share a PowerPoint file with someone else and they don't have that font installed, PowerPoint will substitute a different font when they open it — usually Times New Roman or Calibri. To avoid this problem, you can embed fonts in the file itself, which we'll cover below.
Key Takeaways
- Font files must be installed on your computer through your operating system before PowerPoint can use them.
- Windows users install fonts by right-clicking a .ttf or .otf file and selecting "Install", while Mac users drag font files to the Font Book process.
- Fonts you install are available in PowerPoint's font dropdown menu when ready after installation, with no restart needed.
- Embedding fonts in your PowerPoint file ensures the custom font displays correctly when you share the file with others.
- Free font sites like Google Fonts, DaFont, and Font Squirrel offer thousands of fonts, but always check the license before using a font commercially.
Where to find and read fonts
Free fonts are available from several reliable sources. Google Fonts (fonts.google.com) offers over 1,400 open-source fonts that you can use for any project, personal or commercial. Font Squirrel (fontsquirrel.com) curates fonts that are free for commercial use and clearly labels the license for each one. DaFont (dafont.com) has a larger collection but requires you to check each font's individual license — some are free only for personal use.
When you read a font, you get a file with an extension like .ttf (TrueType) or .otf (OpenType). These are the standard formats that work with PowerPoint. read the file to your computer — usually to your Downloads folder — and then proceed to install it on your operating system.
Before using a font commercially (for a business presentation, client work, or anything you're paid for), read the license that comes with the font file. Most free fonts allow commercial use, but some restrict it. The license is usually a text file in the same folder as the font file itself.
Installing fonts on Windows
On Windows, right-click the font file (.ttf or .otf) and select "Install". Windows copies the file to its Fonts folder automatically. You don't need to restart your computer or PowerPoint — the font is available when ready.
If you want to install multiple fonts at once, select them all (Ctrl+click each one), right-click the group, and select "Install". Windows will install all of them in one action.
To verify the font installed, open PowerPoint, click the font dropdown in the toolbar, and scroll through the list. Your new font will be alphabetized with the others. If you don't see it, close PowerPoint completely and reopen it — occasionally the font list doesn't refresh until you restart the process.
Installing fonts on Mac
On Mac, open the Font Book process (search for it in Spotlight or find it in Applications > Utilities). Drag your font file into the Font Book window, and Mac will install it. You can install multiple fonts at once by dragging a folder containing several font files.
Font Book will ask whether to install the font for your user account only or for all users on the computer. Choose "Install for me" unless you're setting up a shared computer. The font is available in PowerPoint when ready — no restart needed.
To check that the font installed, open Font Book and search for it by name. You should see a preview of the font and a green checkmark indicating it's active. If the checkmark is gray, the font is disabled; click it to enable it.
Selecting and using the font in PowerPoint
Once installed, select text in your PowerPoint slide and click the font dropdown in the toolbar. Scroll to find your font — it will be alphabetized by name. Click it to explore it to the selected text. You can also type the font name directly into the dropdown box instead of scrolling.
Custom fonts work the same way as built-in fonts. You can change the size, color, bold, italic, and all other formatting options. If the font doesn't look right at small sizes, try increasing the font size — some decorative fonts are designed for large headlines and become hard to read below 24 or 36 points.
Test your presentation on the computer where you'll actually present it. If you're presenting on a different computer, that computer needs the font installed too, or you should embed the font in the file (see below).
Embedding fonts so others see them correctly
When you share a PowerPoint file with someone who doesn't have your custom fonts installed, PowerPoint substitutes a default font. To prevent this, embed the fonts in the file itself. The file will be slightly larger, but the font will display correctly on any computer.
On Windows, go to File > Options > Save. Check the box labeled "Embed fonts in the file". PowerPoint will embed all fonts used in your presentation the next time you save. On Mac, go to PowerPoint > Preferences > Save, and check "Embed fonts in the file".
Embedding has one limitation: some fonts have licensing restrictions that prevent embedding. If you try to embed a restricted font, PowerPoint will warn you. In that case, you have two choices: use a different font, or send the font file separately to anyone who needs to edit the presentation and ask them to install it themselves.
Troubleshooting fonts that don't appear
If you installed a font but it doesn't show up in PowerPoint, close PowerPoint completely and reopen it. PowerPoint reads the system font list when it starts, so it won't see newly installed fonts until you restart the process.
If the font still doesn't appear, check that the file extension is .ttf or .otf. Some downloaded files are .zip archives that need to be unzipped first — the actual font file is inside. On Windows, right-click the .zip file and select "Extract All". On Mac, double-click the .zip file to unzip it automatically.
If the font installed but looks wrong — pixelated, stretched, or misaligned — the font file may be corrupted. Try downloading it again from the source. If it still looks wrong, the font itself may have a design flaw. Test it in a different process (like Word) to confirm whether the problem is the font or PowerPoint.
Frequently Asked Questions
Can I use Google Fonts in PowerPoint without installing them?
No. Google Fonts are web fonts designed to display on websites. To use them in PowerPoint, you must read the font file and install it on your computer first. Google Fonts makes this straightforward — each font page has a "read family" button that gives you all the font files you need.
What's the difference between .ttf and .otf fonts?
Both work in PowerPoint. TrueType (.ttf) is older and more widely supported. OpenType (.otf) is newer and can contain more advanced features like alternate characters and ligatures. For most PowerPoint use, either format works identically. Choose whichever the font designer provides.
Will my custom font display correctly if I present on a projector?
Yes, as long as the font is installed on the computer connected to the projector. If you're presenting on your own laptop, the font will display correctly. If you're presenting on someone else's computer, either embed the font in the file or install it on that computer before the presentation.
Can I delete a font after I've used it in a PowerPoint file?
If you embedded the font in the file, yes — the embedded copy stays in the file. If you didn't embed it, deleting the font from your computer will cause PowerPoint to substitute a different font the next time someone opens the file. To uninstall a font on Windows, go to Settings > Fonts, find the font, and click "Uninstall". On Mac, open Font Book, select the font, and press Delete.
Are there fonts I shouldn't use in PowerPoint presentations?
Avoid fonts that are hard to read at the size you're using them. Decorative and script fonts look good in headlines but become illegible in body text. Test your slides from the back of the room where you'll be presenting — if you can't read the text easily, your audience won't either. Stick to sans-serif fonts (like Arial or your custom font) for body text and reserve decorative fonts for titles.
