Change the Terminal Font Size

Regolith sets the font of its GNOME Terminal profile, named “Regolith”, from the gnome.terminal.font Xresources key. By default, this is the monospace font of the current look. The steps are the same in the X11 (i3) and Wayland (sway) sessions.

1. Look up the current value with xrescat gnome.terminal.font in the X11 session, or trawlcat gnome.terminal.font in the Wayland session. With the default look, it is BitstreamVeraSansMono Nerd Font 12.

2. Create or add the following value to your ~/.config/regolith3/Xresources file, with the font name and the size you want. For example, the default font in size 14:

gnome.terminal.font: BitstreamVeraSansMono Nerd Font 14

To use another font, install it first. For example, after sudo apt install fonts-jetbrains-mono you can use JetBrains Mono 14. fc-list : family lists the names of the installed fonts.

3. Reload the Xresources configuration:

regolith-look refresh

The Regolith profile is updated, and open GNOME Terminal windows change to the new font.

This only applies to GNOME Terminal. If you use another terminal, set the font in that terminal’s own configuration. To stop Regolith from changing the GNOME Terminal profile at all, set gnome.terminal.update: false.
