Hi,

I have to reproduce a book layout that was done in Adobe Indesign, and I don't really manage to get the right fontsizes, i.e. according to Acrobat Pro the fonts are consistently a bit smaller then expected.
That may well be an Adobe problem, it's just that I have to aim for rather specific target values... As you can see below the deviation is not so significant with the normal font size and bigger sizes, but more so with the smaller sizes.


% ----------------------------------------------------------------------
\setupbodyfont[10pt]
\definebodyfontenvironment
                [default]
                [xx=0.7,
                x=0.85,
                a=1.175,
                b=1.5,
                ]

\starttext


{\tfxx Smallest } % => expected 7pt, actual 5.98pt

{\tfx Small} % => expected 8.5pt, actual 7.97pt

{\tf Normal} % => expected 10pt, actual 9.96pt

{\tfa Larger} % => expected 11.75pt, actual 11.71pt

{\tfb Largest} % => expected 15pt, actual 14.94pt

\stoptext
% ----------------------------------------------------------------------

Any ideas, how I could get that right? (The project uses Noto Serif, but the same happens there.)

Thanks for you help,
Denis

The TeX point is smaller than the PostScript/DTP point.
Use the unit "bp" to get the same sizes as in desktop apps.

Thanks for your help. That's already better. The base font size, and the bigger sizes are correct now. But it still does not work with the smaller sizes:

% ---------------------------------------
\setupbodyfont[10bp] 
\definebodyfontenvironment
	[10bp]
	[xx=7bp,
	x=8.5bp,
	a=11.75bp, 
	b=15bp,
	] 

\starttext


{\tfxx Smallest } % => expected 7pt, actual 6pt with LM Roman 7

{\tfx Small} % => expected 8.5pt, actual 8pt with LM Roman 9

{\tf Normal} % => expected 10pt, ok

{\tfa Larger} % => expected 11.75pt, ok

{\tfb Largest} % => expected 15pt, ok

\stoptext
%-------------------------------------------------------

Maybe that's an issue with optical sizes?

Best,
Denis

This question is still not resolved. Maybe someone has another hint?

Best,
