Hello Hraban

I have no doubt been feeding in erroneous information in the layout, and not giving ConTexT what it really needs (and in fact all I really require is  typeset page 24 picas wide, 40 picas deep, with a headline 12 point above the top line of text).  At any rate, here is what I have so far  (the width of 627points is supposed to account for margin and edge areas, and the height of 522 points is experimental - actually not enough as the lower crop marks come into the text area):

\definepapersize[OUPoctavo][width=627pt, height=522pt]%offset=100pt?

\setuppapersize[OUPoctavo][A4] % paper size, printed on A4

\definelayout[GHIL]

      [edge=48pt,

      edgedistance=6pt,

      margin=72pt,

      margindistance=6pt,

      topspace=48pt,

      header=12pt,

      headerdistance=12pt,

      height=40pc,

      width=24pc,

      footerdistance=6pt,

      footer=12pt,

      bottomdistance=12pt,

      bottom=36pt,

      location=middle,

      marking=on,

      horoffset=60pt,

      veroffset=0pt,

      paper=OUPoctavo,

      cutspace=0pt]

\setuplayout[GHIL]


Best wishes

Please show this in a minimal example. The following works for me:

\setuppapersize[A4][A4,oversized]
\setuplayout[location=middle,marking=on]

\starttext
\showlayout
\stoptext
