How to set the terminal to open maximized

Launch gnome-terminal as such:

gnome-terminal --window --maximize

If you want gnome-terminal to open fullscreen when you open it with Gnome Do or the Applications menu, put the following into a file named gnome-terminal.desktop and put that in ~/.local/share/applications.

[Desktop Entry]
Name=Terminal
Comment=Use the command line
TryExec=gnome-terminal
Exec=gnome-terminal --window --maximize
Icon=utilities-terminal
Type=Application
X-GNOME-DocPath=gnome-terminal/index.html
X-GNOME-Bugzilla-Bugzilla=GNOME
X-GNOME-Bugzilla-Product=gnome-terminal
X-GNOME-Bugzilla-Component=BugBuddyBugs
X-GNOME-Bugzilla-Version=2.32.0
Categories=GNOME;GTK;Utility;TerminalEmulator;
StartupNotify=true
OnlyShowIn=GNOME;
X-Ubuntu-Gettext-Domain=gnome-terminal

Then log out and log back to apply the changes.


  • Open a Terminal.
  • From Edit menu select Profile Preferences.
  • Tick Use custom default terminal size and enter a default size that is too large for the screen e.g. 240 columns and 100 rows.

Close, then open a new Terminal by clicking the icon (or press Ctrl + Alt + T): the new terminal window should be maximised.
