How to change font size in Eclipse for Java text editors?

Question

I have just tried to change my font size in Eclipse 3.6.0 in the following way:

General → Appearance → Colors and Fonts → Java Editor text font

However, the font size only changed in the file I had open. How can I change the font size for all Java files and projects I open in Eclipse?

FYI, if you want to change all editors at the same time, select General → Appearance → Colors and Fonts → Basic → Text Font. — Philip Murphy, Oct 10 '12 at 00:17

Not sure if this is because changes were made beforehand, but I had to make changes to both "Basic" and "Java". The former affected things like the JSP editor, the latter affected the java programming window — IcedDante, Dec 10 '14 at 14:51
**Eclipse Neon (4.6)** added `Ctrl` + `+` and `Ctrl` + `=` for **Zoom In** and `Ctrl` + `-` for **Zoom Out**. See http://www.eclipse.org/eclipse/news/4.6/M4/ — Elrond_EGLDer, May 19 '16 at 13:41

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 Window → Preferences
Set the font size, General → Appearance → Colors and Fonts → Java → Java 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 Window → Preferences.

Note Be sure to check out the ChandraBhan Singh's answer, it shows the key bindings to change the font size.

The Eclipse-Fonts extension will add toolbar buttons and keyboard shortcuts for changing font size. You can then use AutoHotkey to make Ctrl + mousewheel zoom.

Under menu Help → Install New Software... in the menu, paste the update URL (http://eclipse-fonts.googlecode.com/svn/trunk/FontsUpdate/) into the Works with: text box and press Enter. Expand the tree and select FontsFeature as in the following image:

Eclipse extension installation screen capture

Complete the installation and restart Eclipse. Then you should see the A toolbar buttons (circled in red in the following image) and be able to use the keyboard shortcuts Ctrl + - and Ctrl + = to zoom (although you may have to unbind those keys from Eclipse first).

Eclipse screen capture with the font size toolbar buttons circled

To get Ctrl + mouse wheel zooming, you can use AutoHotkey with the following script:

; Ctrl + mouse wheel zooming in Eclipse.
; Requires Eclipse-Fonts (https://code.google.com/p/eclipse-fonts/).
; Thank you for the unique window class, SWT/Eclipse.

You can have a look at Eclipse color theme, also which has a hell of a lot of options for customizing font, background color, etc.

After *Colors and Fonts*, isn't it something like *Java* → *Editor* → *Java Editor Text Font (set to default: Text Font)* (two more levels interjected)? (Seen in [Eclipse v4.6 (Neon)](https://en.wikipedia.org/wiki/Eclipse_%28software%29#Releases), but for C/C++). – Peter Mortensen Jan 01 '17 at 14:21
Does not work for me in Neon.2, at least on the Java file I'm looking at. – Mathieu K. Feb 03 '17 at 16:23

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.

Try the tarlog plugin. You can change the font through Ctrl++ and Ctrl-- commands with it. A very convenient thing.

If you are using STS, then goto STS/Contents/Eclipse directory and open the STS.ini file.

From the STS.ini file, remove the flooring line:

-Dorg.eclipse.swt.internal.carbon.smallFonts

And restart the STS.

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-size:13;
  font-family: Helvetica, Arial, sans-serif;
  font-weight: normal;
}

you can even change Font Family if you like.

For Windows Users add the following piece of css at BOTTOM of these files: File Names: e4_default_gtk.css & e4_default_win.css
For Mac Users: e4_default_mac.css
