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?

Solution 1

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.

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.

Checked on MARS on 12/18/2015 and still works just fine. Thanks man!

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), but for C/C++).

How are preferences saved? Pressing button OK?

Appears to be the same answer as 4539511.

If we're talking about the menu bar, this is the same answer as 4539511.

Does not work for me in Neon.2, at least on the Java file I'm looking at.

[Daniel Hári]

For other languaged keyboards (like Hungarian): CTRL SHIFT (+) CTRL SHIFT (-)

[Pierpaolo Cira]

For Mac OsX use CMD key instead of Ctrl

[M. Atif Riaz]

Yes this is more applicable as it is global settings

The Window -> Preferences menu is still there in NEON.

Project is not active anymore.

Edit Eclipse toolbar>Window> @BenniMcBeno.

For me Ctrl - to decrease, but Ctrl Shift + to increase.

[DwB]

This is still correct in Eclipse v 4.9 (2018)

Open the java file and use Command and +/- to increase/decrease the font size
