How to upscale the interface of IntelliJ IDEA/WebStorm?

intellij-idea webstorm high-dpi

Solution 1:

You can change UI font size in File | Settings | Appearance & Behavior | Appearance, Override default fonts

Update: starting with version 2017.2 IDEA/WebStorm support per-display-DPI mode on Windows, but it doesn't work always. If you experience problems with scaling, try setting UI font to default in Settings | Appearance & Behavior | Appearance – uncheck Override default font, if it’s checked. If it doesn’t help, please add -Dsun.java2d.uiScale.enabled=false to VM options using menu Help | Edit custom VM options.
