Menu font too small to read

[newguy778]

I am running Linux Mint 19.3 XFCE.  I installed Gimp with my software manager and the menu has a font size that is too tiny to read.  I thought that maybe it would help to run a more recent version of Gimp so I removed the Gimp 2.8 and downloaded and installed GIMP 2.10.18.  But the font is still too small.  Below is my laptop information.  I tried to do an Internet search trying to find out how to fix this problem and there are countless "solutions" and I ended up having to re-install my operating system after I had it so screwed up I couldn't fix what I had messed up.  I thought I'd come to this forum and ask for help before I screw my computer up again.  Thanks in advance for any help you can give me.
