LibreOffice Calc change font of built-in row and column headers/headings

Hi, how to make the 123, ABC appear in custom font (and font size) please? (I have changed the default font but it doesn’t change the appearance of the headers)

upvoted so that you might post a screenshot.


AFAIK You can not change only the font of the row and column headings: the change will also affect the other elements of the interface (menu, status bar, dialogs, sidebar…). To do that:

  • ToolsOptionsLibreOfficeFonts: Tick Apply replacement table,
  • Replacement Table:
  • Font: select Segoe UI
  • Replace with: select select the one you want
  • Click the green check mark
  • Tick Always then click Ok


Thank you for that Pierre-Yves.
My question was not good-it was the font SIZE I wanted to change!
That setting appears to change the font, but not the size.
Is there a setting somewhere for the font size?

Hi @Piecevcake - No option managed by LibreOffice. See perhaps via the operating system that handles this mechanism?

I don’t think so! In Excel the font of the rows and headers is the font (size, colour, etc) chosen as “normal” in the individual workbook. No other app is going to determine this!

Can anyone else assist with the location of the font size setting?
