Depends on the document class you are using, but mostly it is 10pt.

  • book: Default is 10 pt, other available options are 11 pt and 12 pt.
  • report: Default is 10 pt, other available options are 11 pt and 12 pt.
  • letter: Default is 10 pt, other available options are 11 pt and 12 pt.
  • proc: Default is 10 pt, other available options are 11 pt and 12 pt.
  • ext versions of the above (extarticle,extreport, extbook, extletter, and extproc) (the extsizes): Again, Default is 10 pt, other available options are 8pt, 9pt, 11pt, 12pt, 14pt, 17pt, and 20pt.
  • The ams class (amsart, amsbook and amsproc), coming from the ams-LaTeX collection prepared by the American Mathematical Society: Default is 10 pt, other available options are 11 pt and 12 pt.
  • memoir: Default is 10 pt, other available options are 9pt, 11pt, 12pt, 14pt, 17pt, 20pt, 25pt, 30pt, 36pt, 48pt,60pt. Option extrafontsizes is available to indicate that you will be using scalable fonts that can exceed 25pt.
  • beamer: Default is 11 pt, other available options are 8pt, 9pt, 10pt, 11pt, 12pt, 14pt, 17pt, 20pt.
  • koma-script (scrartcl, scrbook, and scrreprt): Default is 11 pt. KOMA-Script does not use fixed fonts and attributes to emphasize different elements of the text. Instead there are variables that contain the commands used for changing fonts and other text attributes.
