How to Install Custom Fonts on a Debian 10 System

Your operating system and all its applications usually maintain a set of fonts that you can use as system fonts and in various desktop and web applications respectively. Let us suppose you want to use a new font that you saw on the internet in any of your applications. Unfortunately, it is not as simple as just selecting a downloaded font and then start using it in the application. You need to first install that font on your operating system in order to use it.

In this article, we will explain how to add and use a downloaded font on your Debian 10 Buster system.

It is important to note that adding too many custom fonts can slow down your system. Therefore it is best practice to install very few custom fonts and preferable delete the ones you are done with using. However, you should not delete the default set of fonts that come with your system by default. The slow speed happens because the operating system has to keep a track of all the installed fonts and load them when you open an application requiring the use of fonts.

Viewing Fonts Installed on your System

While working on LibreOffice Writer, you can select a font from the fonts drop-down. These fonts are a part of fonts installed on your operating systems.

View Fonts

You can view which all fonts are available on your system by accessing the Gnome Fonts file through the Application Launcher Search as follows:

Download font file on the shell

Your Downloads folder will now contain the bakery.ttf file.

The Font Manager provides a very effective way to install a downloaded font to your system. The Font Manager can be downloaded through the Debian Software Manager or through the command line by entering the following command in the Terminal:

Install a Downloaded Font

Here we are adding the Bakery font to our system by accessing its .zip file from the Downloads folder. After selecting the zip file, the font will be installed in your system.

Please note that only the user that has installed the font can use it, as the font installed this way is stored in that user’s /local/share/fonts directory.

Now, this font will also be visible in the fonts list of LibreOffice.

Install Fonts for All Users

You may wish to install it only for yourself or for all users accessing your system. You can download a font both through a web browser or through command line depending on what you prefer.
