i found the best way to increase font size in eclipse:

follow this path : eclipse-folder\plugins\org.eclipse.ui.themes_1.2.100.v20180514-1547\css

--there are a bunch of files here and it depends on user system which file to change.

* {
  font-family: helvetica, arial, sans-serif;
  font-weight: normal;

you can even change font family if you like.

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 windowpreferences. drill down to: (generalappearancecolors and fontsbasictext 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

if you are changing the font size, but it is only working for the currently open file, then i suspect that you are changing the wrong preferences.

  • on the eclipse toolbar, select windowpreferences
  • set the font size, generalappearancecolors and fontsjavajava editor text font).
  • save the preferences.

check that you do not have per-project preferences. these will override the top-level preferences.

eclipse v4.2 (juno) note

per comment below, this has moved to the eclipse preferences menu (no longer named the window menu).

eclipse v4.3 (kepler) note

the window menu is live again, that is, menu windowpreferences.

eclipse 2021-12 note

verified that the path described (window → preferences, general → appearance → colors and fonts → java → java editor text font) is still correct.

note be sure to check out the chandrabhan singh's answer, it shows the key bindings to change the font size.
