Hello Hraban,
thanks for your tip.
Hopefully I'll find time to have a look at it after that busy weekend.
Regards

Thank you Wolfgang,
I guess I'm thinking too complicated. Ultimately, this should result
in a type area according to the golden ratio.
(textheight = 660 pt = 1.618 * textwidth or something similar,
depending on the font size or interlinespace)
To simplify your code, you can replace many of these measures with
units, e.g. th, tw; see also lowlevel-registers.pdf
Perhaps this can help. It works for me. It lays out his page 155 (1st
edition paperback) bottom page, which has a 1.7 ratio type area on a 1.5
ratio page.
