Hi,

I have to reproduce a book layout that was done in Adobe Indesign, and I do=
n'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 sign=
ificant with the normal font size and bigger sizes, but more so with the sm=
aller sizes.


% ----------------------------------------------------------------------
\setupbodyfont[10pt]
\definebodyfontenvironment
                [default]
                [xx=3D0.7,
                x=3D0.85,
                a=3D1.175,
                b=3D1.5,
                ]

\starttext


{\tfxx Smallest } % =3D> expected 7pt, actual 5.98pt

{\tfx Small} % =3D> expected 8.5pt, actual 7.97pt

{\tf Normal} % =3D> expected 10pt, actual 9.96pt

{\tfa Larger} % =3D> expected 11.75pt, actual 11.71pt

{\tfb Largest} % =3D> expected 15pt, actual 14.94pt

\stoptext

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

Thanks for you help,
Denis
