PhpStorm - How to change default zoom level

The default zoom level is way too high as you can see in the following screenshot, how can I change it?

I already searched the whole settings but found nothing.

Editor font size can be changed in Preferences | Editor | Colors&Fonts | Font (don't forget to press Save as button to save the default schema as a custom one - predefined schemes can't be modified). Note also that you can zoom the font in editor. To zoom text using keyboard, you need to assign preferred shortcuts to Increase font size, Decrease font size and Reset font size actions in Preferences | Keymap | Editor Actions; to do the same using mouse, enable Change font size (Zoom) with Ctrl+Mouse Wheel option in Preferences | Editor | General and use Ctrl+mouse wheel to zoom
