: GIMP - How do I change UI DPI? This is a problem I have been having recently. My screen size has a pretty high pixel density and, as a result, all of GIMP's icons are criminally small and

I have gimp 2.8 on Windows 10 and this is what solved the small tool icons problem for me:
open This PC > Local Disc (C:) > Program Files > GIMP 2 > bin,
right click on gimp-2.8,
open Properties,
click on Compatibility.
On the settings options select:
Override high DPI scaling behaviour.
Scaling performed by,
scroll and select System,
Apply,
OK

The size of the tool icons (brush, move, selection etc) of GIMP's UI can be configured in the gtkrc file.
Try find this line in gtkrc file:

GimpToolPalette::tool-icon-size = <size>


Where <size> is an written identifier (instead of a number like you might expect), with names like


menu
button
large-toolbar


I personally set my icon sizes to button which is bigger than the default (which I think is menu).
I think large-toolbar is the biggest.

So maybe try something like changing the line to:

GimpToolPalette::tool-icon-size = large-toolbar

You can use Kevin Payne's themes with big icons: these are available and discussed here.
