Eclipse - globally change font size

There are a lot of settings for the fonts in Eclipse in the menu Window -> Preferences -> General -> Appearance -> Colors and Fonts. But this is very detailed and it is hard to find out which settings effects which text.

But if you want to make a global change to all fonts sizes in Eclipse, got to the folder plugins/org.eclipse.ui.themes_ ... /css/dark and edit the css file corresponding to your theme. In my case I am using theme dark, I had to change e4-dark.css. Add the following lines at the end:

* {
    font-size: 14;
}

for larger text. To get smaller text use

* {
    font-size: 8;
}
