Thank you, Hans. I have to refresh my knowledge about the syntax and
I'll try it out. Making
    \setbox0\vbox{#1}
and then executing the \testpage with "ceil(ht0 / lineheight)" should
then work OK, I hope.


I understand the problem of the approach that I asked for: as soon as
someone enters a \vfill(l) or \vss, it's approximately impossible to
determine where the text on the page ends. But in the first
approximation I would be satisfied with the empty space that would
remain if the document ended at that specific place.

That information is also very valuable when trying to put pictures on
slides, where picture has to be as big as possible, but still has to
fit on the space under the title (I tuned them manually, which was OK
for just a couple of slides).

Thank you,
