I want to use the font "CMR12" I googled it but didn't get any helpful results.


1) How do I change the font in my latex to this font?

2) What happens to the math equations if I use this font? will it screw everything up?

System info: Mac OS X el capitan


documentclass[12pt]{…} and no font loading, no T1 font encoding. cmr is the default font. However, note if you need accented letters, you'd have better write \usepackage[T1]{fontenc}\usepackage{lmodern}.

  • this doesn't usually use cmr12, but it will have math set up properly. – barbara beeton Apr 30 '16 at 17:51
  • Hi @barbarabeeton, what do you mean by "this doesn't usually use cmr12 "? – HappyBee Apr 30 '16 at 18:15
  • @barbara beeton: same question. The default font is cmr, isn't it? – Bernard Apr 30 '16 at 18:16
  • the computer modern fonts have different design sizes, so cmr10 glyphs have slightly different shapes than the corresponding glyphs in cmr12. for those two sizes the difference is minimal and barely noticeable, but if you compare cmr7 or cmr5 you can notice quite distinct differences. the smaller sizes are relatively wider, so they can be read more clearly in sub- and superscripts, and won't fade away so quickly in photocopying. – barbara beeton Apr 30 '16 at 19:43
  • Technically, you need neither fontenc nor lmodern in order to use accented characters. – Mark May 1 '16 at 1:07
