How do I make Ariel my default font?

I would like not to have to keep selecting my chosen font (Ariel) every time I want to write a document with LibreOffice.

If you are talking about Math (which is suggested by the math tag of your question), then use FormatFonts to define your preferred font settings, and press Default button there.

If that’s Writer, then use ToolsOptionsLibreOffice WriterBasic Fonts to define default fonts for new documents, or create a template with font settings and make it default.

(Ariel must be a beautiful font btw :slight_smile: )
