Changing Text Files (.txt) "Preview" (edit: "Quick Look") font size in macOS Finder


Does anybody know how to change the “Preview” (edit: “Quick Look”) for text files (.txt) monospace system font size in macOS? I find it tiny and work with text files a lot.

Thank you,

By “Preview” do you mean Quick Look? If I remember correctly, it’s possible to do Quick Look plugins where you could possibly alter the view to be whatever you want.

Yes, with Quick Look.

I just was able to find the name of a tool that allowed me to do it in the past — TinkerTool. Thankfully, it’s still being supported and updated for macOS 10.13 High Sierra.
