Consider a non-English document compiled in XeLatex, the standard font size is equal for all English and non-English text. How is it possible to set the size of the English text and change the font face?

How can XeLaTeX indentify the languages? Give an example of some lines in form of a MWE. – Keks Dose Sep 2 '12 at 19:08

You can use Polyglossia features: if \englishfont is defined, then XeLaTeX will use it for English text.


\setmainfont{Linux Libertine O}
\newfontfamily{\englishfont}{Linux Biolinum O}


Testo in italiano.

Text in English.

\latin and \persian is better than \begin{english} – seyed Oct 6 '13 at 6:31
This is probably a silly question, but how does one set different font sizes for particular languages as indicated in the title of this post? I don't see it in the MWE. – camatkara Nov 13 '14 at 12:24
@camatkara For sizes, use the Scale option to \newfontfamily. – egreg Nov 13 '14 at 13:13
Thanks @egreg, got it working. – camatkara Nov 13 '14 at 16:01
@seyed I would also prefer the simpler \latin{} command, but the \begin{english} environment is the only thing that's worked in properly hyphenating English for me. Can you elaborate? Thanks. – camatkara Nov 13 '14 at 16:02
