Superscript text size

Superscript text size

[morgan.brassel]

Hi,

The superscript in expressions like $R^N$ seems to be typeset with a bigger font
size in ConTeXt than in LaTeX. Is it the wanted behaviour? From the typographic
point of view, which is the best of the two renderings?

Thanks for your advice,

Morgan

That should not happen. I cannot see the different from my eyes. Here is 
my example. In both cases, bodyfont is 10pt, and scriptsize is 7pt. Do you 
see the differece?

ConTeXT:

\setupbodyfont[10pt]
\starttext $R^N$ \stoptext


LaTeX:

\documentclass{minimal}
\usepackage{lmodern}
\begin{document}
   $R^N$
\end{document}

As far as my eyes can see, the results are the same with 10pt and 11pt as
document text size, but not with 12pt. Your two examples in 12pt look different
to me. Am I wrong?

context fonts sizes are not modelled after latex so i can imagine such 
differences to exist

In the latex example, you need to change the document class to article, if 
you want 12pt fonts. To my eye, there is no difference between the two. 
But pdffonts tells me that latex is using LM Math Italic 8pt while ConTeXt 
is using LM Math Italic 9pt. This is not conclusive evidence since the 
fonts could be scaled.

In any case, if you want to change ConTeXt's defaults for 12pt, you can 
redefine the following

\unprotect
\definebodyfontenvironment
   [\!!twelvepoint]
   [        \s!text=\!!twelvepoint,
          \s!script=\!!ninepoint,
    \s!scriptscript=\!!sevenpoint,
               \c!x=\!!tenpoint,
              \c!xx=\!!eightpoint,
             \c!big=\!!fourteenpointfour,
           \c!small=\!!tenpoint]
\protect

This is just copied from font-ini.tex. You can use 12pt, 11pt etc rather 
than the predefined macros if you want.

Yes, it seemed to me that the font was a bit larger in ConTeXt than in LaTeX, so
9pt vs 8pt seems coherent with that feeling. Of course, I had to zoom to see a
real difference...

Thank you for this solution. I'll try it if I don't get used to the ConTeXt
size.
