Bug: Tiny UI text in Calibre reader, but ebook text is fine

Simons Mith · 06-24-2025, 12:18 PM

This new Win11 laptop has a 3840x2400 display. Fresh install of Calibre was done about a month ago. In order to make everyday text readable, I have set the Scale setting to 300%. Works fine in most places, but as you can see from the attached screenshot, the Calibre Reader is not taking any notice /for its own UI settings/. I see nowhere in the Preferences section to adjust this. The ebook text itself is absolutely fine. Guess I'll live with whatever the default settings are, for now.

Change the Interface font in the Library Manager:

Thanks for the pointer. Fixed now. The viewer has inherited sensible text size settings from the main program.
That was quite hard to correct, because the default text size was 3pt and it was a struggle to read. I do assume there's a magnifier tool somewhere on this system but I managed without it, if barely.
