I'm using Gimp for Mac on a 4k screen and the interface text and icons look tiny. How can I make it bigger?

Change icon size

  • Preferences
    • Interface
      • Icon Theme
        • Change: guess Icon size from resolution
        • Into: custom Icon Size
        • Drag slider

Change font size

  • Close Gimp
  • Open the file gtkrc of your specific theme in a text editor
    • Open the Gimp themes directory:
      • Mac: /Applications/GIMP-2.10.app/Contents/Resources/share/gimp/2.0/themes/
      • Windows: C:\Program Files\GIMP 2\share\gimp\themes\
      • Ubuntu: /usr/share/gimp/2.0/themes/
    • Open the gtkrc file for your theme:
      • Light: Light/gtkrc
      • Dark: Dark/gtkrc
      • Gray: Gray/gtkrc
      • System System/gtkrc
      • other
        If you have a customized Gimp, look here for the gtkrc file
        • Mac: ~/Library/Application Support/GIMP/2.10/themes
  • Find line with: GimpDock::font-scale = 0.8333
  • Replace with: GimpDock::font-scale = 1.6666 (or another value)
  • Start Gimp

    Custom Icon size behaves strangely: large and huge are smaller than medium size on my DELL xps 15 4k (gimp 2.10.18) gitlab.gnome.org/GNOME/gimp/issues/2313

  • Linux equivalents in Ubuntu are in /usr/share/gimp/2.0/themes/Dark/gtkrc and similar for the other themes Jun 11, 2021 at 14:14

  • This works for almost every UI element, but the main menu bar is still small for me. I suppose that's being controlled by the desktop environment.

Under Bodhi Linux a better solution for me is similar to Bouke Versteegh's except leave.

GimpDock::font-scale = 0.8333

alone. Instead, uncomment

# font_name = "sans 10"

and change it to

font_name = "sans 20".

If you examine the gtkrc file, you will see there are several places where various font scales are specified. Changing the font changes them all without fussing with specific scales. If you want to tweak it afterwards, then you can alter specific scaling settings to change relative sizes for various parts of the interface.

Note: I had previously altered the bootup system environment variables with

GDK_SCALE=2

which GIMP apparently does not honor. My menu bar remained unreadable when I only adjusted the scale in gtkrc.
