It’s not. You misunderstand. You sent an example
\startTEXpage[offset=1em] \framed{M} \framed{\tfxx M} \framed{\tfd M} \stoptext
where all the frames had the same size, but that’s only because you hardcoded it earlier in the file:
\setupframed [offset=none, framecolor=red, rulethickness=0.01pt, width=12pt, height=12pt]
Notice how the width and height are both set to 12pt? Obviously the frames are going to have fixed sizes then. If you remove that artificial setting, the frames are allowed to grow and shrink as expected.
Or am I missing something.
Quite a bit, I’m afraid. Later in this thread you’ll see that Hans is talking about design size, which is a related, yet different issue. Do you understand what he’s talking about?
\definefontfeature[default][default][boundingbox=yes] \setupbodyfont[dejavu] \starttext \input tufte \stoptext
The issue with units per em is something I didn’t understand.
That’s irrelevant for you as a font user. Don’t worry about it.
A user that asks why different fonts have glyphs with different sizes given the same point for both, doesn’t remain a font user anymore.
I have to insist: units per em are not something you should worry at all unless you’re designing the font yourself.
Best,
