Where fonts go and how your computer finds them
A font is a file your computer reads to display text in a particular style. When you install a font, you're copying that file to a folder where your operating system looks for fonts automatically. Once it's there, every program on your computer — Word, email, design software, web browsers — can use it.
The process is straightforward: find the font file, move it to the right folder, and restart any programs that were open. On Windows, fonts live in a system folder. On Mac, they live in a different system folder. Both operating systems check these folders when they start up, so new fonts appear in your program menus after a restart.
Font files usually come as .ttf (TrueType) or .otf (OpenType) files. You'll download them from a website, find them in a folder on your computer, and then move them to the system fonts folder. The steps differ slightly between Windows and Mac, but the idea is the same.
Key Takeaways
- Font files (.ttf or .otf) must be moved to your system fonts folder before any program can use them.
- On Windows, the fonts folder is usually at C:\Windows\Fonts and you can drag files directly into it.
- On Mac, fonts go in /Library/Fonts or ~/Library/Fonts, and you can use Font Book to install them automatically.
- After installing a font, close and reopen any programs that were running so they can load the new font into their menus.
- If a font doesn't appear after installation, check that the file extension is .ttf or .otf and that it copied completely.
Installing a font on Windows
Download the font file to your computer. Most fonts come in a .zip folder that you'll need to unzip first. Right-click the .zip file and choose "Extract All" to see the actual font files inside.
Open File Explorer and navigate to your Downloads folder or wherever you saved the font. You should see one or more files with names ending in .ttf or .otf. Right-click on the font file and select "Install". Windows will copy it to C:\Windows\Fonts automatically. You don't need to move it yourself — the Install option does that for you.
If the Install option doesn't appear, you can drag the font file directly into the fonts folder instead. Open a second File Explorer window and type C:\Windows\Fonts in the address bar at the top. Then drag your font file from the first window into the fonts folder in the second window. Windows will copy it there.
Close any programs that were open when you installed the font, then reopen them. The new font will appear in the font menu the next time you start the program.
Installing a font on Mac
Download the font file and unzip it if it came in a .zip folder. Double-click the .zip file to unzip it automatically, or right-click and choose "Open".
The easiest way to install a font on Mac is to use Font Book, which is built into your system. Double-click the font file (.ttf or .otf) and Font Book will open. Click the "Install Font" button in the window that appears. Font Book will copy the font to ~/Library/Fonts, which is your user fonts folder, and it will be available to all your programs immediately.
If you want to install the font manually instead, open Finder and press Command+Shift+G to open the "Go to Folder" dialog. Type ~/Library/Fonts and press Enter. Drag your font file into this folder. The font will be available the next time you open a program.
Some fonts are installed to /Library/Fonts (the system-wide fonts folder) instead of ~/Library/Fonts (your personal fonts folder). If you have administrator access and want the font available to all users on the computer, you can drag it into /Library/Fonts, but ~/Library/Fonts is usually the right choice for your own use.
What to do if a font doesn't appear after installation
The most common reason a font doesn't show up is that the program was already open when you installed it. Programs load their font list when they start, so they won't see a newly installed font until you close and reopen them. Close the program completely and open it again.
Check that the file you installed actually has a .ttf or .otf extension. Some downloads include preview images or text files with similar names. Right-click the file and look at its properties (Windows) or Get Info (Mac) to confirm the file type. If it says "TrueType Font" or "OpenType Font", it's the right kind of file.
On Windows, make sure the file actually copied to C:\Windows\Fonts. Open File Explorer, type C:\Windows\Fonts in the address bar, and search for the font name. If it's not there, the installation didn't complete. Try dragging it directly into the folder instead of using the Install option.
On Mac, check both ~/Library/Fonts and /Library/Fonts to see if the font ended up in the wrong folder. If it's in /Library/Fonts but you want it in ~/Library/Fonts, move it. Some programs look in both places, but moving it to your user folder is usually cleaner.
Removing a font you no longer need
If you installed a font and decide you don't want it anymore, you can delete it. On Windows, open File Explorer and navigate to C:\Windows\Fonts. Find the font, right-click it, and choose Delete. The font will be removed and won't appear in any program menus.
On Mac, open Finder and navigate to ~/Library/Fonts (or /Library/Fonts if that's where you installed it). Find the font file, right-click it, and choose Move to Trash. You can also use Font Book: open it, find the font in the list, select it, and click the minus button at the bottom of the window.
After you delete a font, close and reopen any programs that were using it. The font will disappear from their menus.
Finding fonts to download
Free fonts are available from many websites. Google Fonts is a large collection of open-source fonts you can download at no cost. DaFont, FontSpace, and 1001 Fonts are other popular sources. Most of these sites let you preview the font before you download it, so you can see what it looks like.
When you download a font from any website, make sure you trust the source. Stick to well-known font sites rather than random links. The file should be a .zip folder containing .ttf or .otf files, not an executable (.exe) or installer file.
Some fonts are commercial and require a license to use. Read the license information on the website before you download. Many free fonts are licensed for personal use only, which means you can use them on your own computer but not in commercial projects or on a business website. If you're using a font for work, check the license to make sure you're allowed to.
Frequently Asked Questions
Can I install a font just for one program instead of system-wide?
Most programs don't have their own fonts folder, so fonts must be installed system-wide. However, some design programs like Adobe Creative Suite and Affinity Designer can load fonts from a folder you specify in their settings. Check your program's preferences or help documentation to see if this option is available.
What's the difference between .ttf and .otf fonts?
Both .ttf (TrueType) and .otf (OpenType) are standard font formats that work on Windows and Mac. OpenType is newer and supports more advanced features like alternate characters and ligatures, but for basic use they're interchangeable. Install them the same way and they'll work in all your programs.
Do I need to restart my computer after installing a font?
No, you don't need to restart your computer. You only need to close and reopen the programs that will use the font. The font will appear in their menus the next time they start.
Why does a font look different in my program than it did in the preview?
Font rendering varies slightly between programs and operating systems. A font might look slightly different in Word than it does in a design program, or on Windows versus Mac. This is normal and doesn't mean the font installed incorrectly. The differences are usually small and related to how each program displays text.
Can I install a font from a USB drive or external hard drive?
No, the font file must be copied to your system fonts folder on your computer's main drive. You can copy it from a USB drive or external drive, but it won't work if the font file stays on the external device. Copy the file to your Downloads folder first, then install it from there.
