LaTeX
The scrartcl class from the KOMA package does some fairly sophisticated calculations to determine an optimal page layout, with the text width set in terms of average characters-per-line, and the text height and location set to provide pleasing proportions based on that and the paper proportions. A sample document (with a framebox to show the text area) is simply:
\documentclass[DIVcalc,twoside]{scrartcl} \begin{document} \noindent\framebox{\rule{0pt}{\textheight}\rule{\textwidth}{0pt}} \end{document}
ConTeXt
The following code duplicates the scrartcl calculations to set the text area and produces a similar sample document, again with a framed box to show the text area. Note that, because this depends on \lineheight
% Set visible page width. \newdimen\PageWidth \PageWidth=\dimexpr(\paperwidth-\bindingcorr)
% Set the textarea height proportional to the width. \newdimen\Height \Height=\dimexpr(\Ratio\Width)
% Set the margin/gutter widths to be equal on a full spread. \newdimen\Back \doifmodeelse{oneside}
{\Back=\dimexpr(((\PageWidth - \Width) / 2) + \bindingcorr)} {\Back=\dimexpr(((\PageWidth - \Width) / 3) + \bindingcorr)}
% Set the top and bottom margins in a 1:2 ratio, ignoring headers. \edef\Top{\the\dimexpr((\paperheight - \Height) / 3 - 3\lineheight)}
% Redefine \Height to include header and footer space. \Height=\dimexpr(\Height + 8\lineheight)
% Set up the page layout using the calculated parameters. \setuplayout[
backspace=\the\Back, height=\the\Height, width=\the\Width, header=2\lineheight, headerdistance=\lineheight, footer=2\lineheight, footerdistance=3\lineheight, topspace=\Top]
\starttext \framed[width=\textwidth,height=\textheight]{} \stoptext
This can be processed with a -mode=BCOR
option on texexec
to activate the binding correction, or with a -mode=oneside
option to activate the single-sided page layout rather than the (default) double-sided version.
