Hello, I'm using the simplefonts module from TeX Live 2013. (I can't use the new simplefonts for this production project, due to stability requirements.) I have the following, which works well for the most part: \setupbodyfontenvironment[default][em=italic] \usemodule[simplefonts][size=9.2pt] \setmainfont[Gentium Book Basic] \setsansfont[Tex Gyre Heros] \starttext Serif typeface: regular, {\em italic}, {\bf bold} and {\bf\em bold italic} styles. \ss Sans--serif typeface: regular, {\em italic}, {\bf bold} and {\bf\em bold italic} styles. \stoptext Because the Tex Gyre Heros font is larger than Gentium Book Basic at a given point size, when I compile this document, there is a size mismatch between the serif and the sans typefaces. So I looked for a way to give the sans font a smaller default size. I couldn't find an example of such at http://wiki.contextgarden.net/simplefonts. I tried this: \setsansfont[Tex Gyre Heros][size=8pt] but it didn't seem to have any effect. Is there a way to do what I'm trying to do? I could use \switchtobodyfont[8pt] every time I go to sans, but I don't think that's the intention of simplefonts. Thanks, Lars
