I understand how to increase the font size within an editor tab, but I'd like to increase the font size of the main navigation menu and most importantly, the tab titles. These do not change when I zoom in or out of an editor tab (using Cmd + mouse wheel on OSX). I do not see anything in the preferences menus.

  1. Settings/Preferences
  2. Appearance & Behavior | Appearance
  3. Enable Use custom font option -- it will allow to change font used for GUI as well override its size.

In prior IDE versions (2018.2 and older) that option was named Override default fonts by:

P.S. The latest 2023.1 version can now zoom the whole thing at once (editor and interface fonts as well as GUI elements): View | Appearance | Zoom IDE.

In v2023.1 it’s possible to zoom into and out of IntelliJ IDEA entirely, increasing or decreasing the size of all UI elements at once.

In 2018.3 the option is called "Use custom font" where you can set font style and size. Same setting dialog...Appearance & Behavior | Appearance
This is a reminder for future me: there is an option in Editor > General > Editor Tabs window called "Use small fonts for labels". If you uncheck this, the tab font size will increase, without having to change the entire UI font.
2021.3 macOS version is randomly making size 13 look like 8, and 14 looks like 20. Random 😃
Breaking news that helped me a lot here: Switch to another tab to make the changes visible!
