Running Eclipse v4.3 (Kepler), the steps outlined by AlvaroCachoperro do the trick for the Java text editor and console window text.
Many of the text font options, including the Java Editor Text Font note, are "set to default: Text Font". The 'default' can be found and configured as follows:
On the Eclipse toolbar, select Window → Preferences. Drill down to: (General → Appearance → Colors and Fonts → Basic → Text Font) (at the bottom)
- Click Edit and select the font, style and size
- Click OK in the Font dialog
- Click Apply in the Preferences dialog to check it
- Click OK in the Preferences dialog to save it
Eclipse will remember your settings for your current workspace.
I teach programming and use the larger font for the students in the back.
