Wine, the Windows emulator for Linux, has gotten to the point where it works pretty well for most non-USB-gadget-related Windows programs that I’m still forced to use. For whatever reason, the out-of-the-box Wine system UI fonts are eye-burning tiny.
Perhaps they’re well suited for 640×480 monitors?
Anyhow, fire up the Wine configuration editor (which may be a menu entry or just type winecfg at a command prompt), go to the Desktop Integration tab, look in the Appearance section, and scroll down through the various Item entries. Some entries enable the adjacent Font button, a click of which will allow you to whack ’em into sensibility.
All the fonts defaulted (for my installation, anyway) to 6 point Andale Mono. Not sensible.
Don’t follow the well-meaning advice you’ll find elsewhere to tweak the Screeen Resolution setting from whatever the default is. That forces Wine to interpolate from Windows dots to X dots and the outcome is not pretty.
