Hi, please regard this minimal example: \setupbodyfont[10pt] \starttext \title{Title} \section{Section} {\switchtobodyfont[big] big} {\switchtobodyfont[small] small} {\tfxx tfxx} {\tfx tfx} {\tfa tfa} {\tfb tfb} {\tfc tfc} {\tfd tfd} \stoptext Latin Modern Regular is available in different optical sizes - lmroman{5,6,7,8,9,10,12,17}-regular.otf - and as context is aware of these sizes (configured in typescripts) I wonder why they are not correctly assigned. This table indicates what happens instead: \tfxx 6pt -> lmroman6 (as expected) \tfx 8pt -> lmroman8 (as expected) \tftf 10pt -> lmroman10 (as expected) \tfa 12.0pt -> lmroman10 (instead of lmroman12) \tfb 14.4pt -> lmroman10 (instead of lmroman12) \tfc 17.3pt -> lmroman10 (instead of lmroman17) \tfd 20.7pt -> lmroman10 (instead of lmroman17) \switchtobodyfont[small] 8pt -> lmroman8 (as expected) \switchtobodyfont[big] 12pt -> lmroman12 (as expected) \title 17.3pt -> lmroman10 (instead of lmroman17) \section 12pt -> lmroman10 (instead of lmroman12) The commands \title and \section and the font size switches \tfa, b, c, and d scale the font to the correct size, however, the wrong optical size is assigned. Note, this is not the case for \tfx, xx and \switchtobodyfont. Tested in MKIV and MKII (current beta). Is this a bug or a feature? Cheers Florian

Most likely the first, however I never really understood how this magic is configured in ConTeXt. The relevant files are tex/context/base/type-siz.mkiv (as well as mkii) I guess that the contents more or less agree with your observations (there is no 17pt font defined for big, however there are small fonts defined for x and xx), but I would have no idea how to fix anything.

Thanks, you are right, the biggest defined lm font is lmroman12. But that's beside the point. The typescripts are configured correctly. BTW, you get the same problem with Wolfgang's third/typescripts/type-optical.tex, which defines four optical sizes of the Adobe Pro fonts. Like Mojca, I don't know about the context magic innards and how to fix this either. Is there a way for interactive line tracing in luatex, similar to e.g. bash -x? Florian
