Hi,
 
\showframe
 
\setuplayout[width=.65\paperwidth,hoffset=1cm,margin=0cm]
\setuphead[chapter][page=right]
 
%\setuppagenumbering[alternative=singlesided]  % horoffset_ss.pdf
\setuppagenumbering[alternative=doublesided]  % horoffset_ds.pdf
 
\starttext
\dorecurse{2}{\chapter{Chapter #1}\dorecurse{8}{\input knuth}}
\stoptext

- horoffset_ss.pdf
 
how do you define horoffset so that for the
 
- odd pages the layout     |horoffset|...|text|...|   is
- even pages the layout    |...|text|...|horoffset|   is
