Everyone has their own preference when it comes to fonts, and some users, like me, are not happy with Ubuntu's huge default fonts.
In the Terminal, enter the following command:
sudo apt-get install ttf-mscorefonts-installer
click here to download
3. Navigate to your /home folder (~/) and press ctrl+h to show hidden files and folders.
4. Create a new folder named .fonts and extract the fonts from the tar file to this folder.
5. Setup your system fonts. Go to Preferences->Appearance->Fonts.
In my system, I have the following font settings:
Document font: Aquabase (9)
Fixed width font: Bitstream Vera Sans Mono Roman (10)
