+%D \macros{setupTypeArea}
+%D Setting up some values.
+%D
+%D Default setup:
+%D
+%D \starttyping
+%D \setupTypeArea[bcor=0pt,oneside=no,alphabets=2.6]
+%D \stoptyping
+%D
+%D Example:
+%D
+%D \starttyping
+%D \setupTypeArea[bcor=3mm,oneside=yes,alphabets=3.1]
+%D \stoptyping
+\def\setupTypeArea[#1]{\getparameters[TA@][#1]\doTypeArea}
+
+%D Some internal dimensions:
+\newdimen\PageWidth \newdimen\Back
+\doifundefined{Width}{\newdimen\Width}
+\doifundefined{Height}{\newdimen\Height}
+
+%D This internal macro does the whole work:
+\def\doTypeArea{
+
+%D Set visible page width:
+\PageWidth=\dimexpr\paperwidth-\TA@bcor\relax
+
+%D Determine the paper aspect ratio:
+\edef\Ratio{\withoutpt{\the\dimexpr2\paperheight/(\PageWidth/32768)\relax}}
+
+%D Set the textarea width to X alphabets:
+\setbox\scratchbox\hbox{\dorecurse{26}{\character\recurselevel}}
+\Width=\dimexpr\TA@alphabets\wd\scratchbox\relax
+\ifdim\Width<\PageWidth\else
+\writestatus{error}{line wider than page}\end\fi
+
+%D Set the textarea height proportional to the width:
+\Height=\dimexpr(\Ratio\Width)
+
+%D Set the margin/gutter widths to be equal on a full spread:
+\doifelse\TA@oneside{yes}
+ {\Back=\dimexpr(\PageWidth - \Width) / 2 + \TA@bcor\relax}
+ {\Back=\dimexpr(\PageWidth - \Width) / 3 + \TA@bcor\relax}
+
+%D Set the top and bottom margins in a 1:2 ratio, ignoring headers:
+\edef\Top{\the\dimexpr(\paperheight - \Height) / 3 - 3\lineheight\relax}
+
+%D Redefine \type{\Height} to include header and footer space:
+\Height=\dimexpr(\Height + 8\lineheight)
+
+%D 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]
+}
+\protect
+
+\setupTypeArea[bcor=0pt,oneside=no,alphabets=2.6]
+
+\doifnotmode{demo}{\endinput}
+
+%D Usage example:
+\usemodule[typearea]
+\setupTypeArea[bcor=0mm,alphabets=3.1]
+\setuppagenumbering[alternative=doublesided]
+\starttext
+\dorecurse4{\framed[width=\textwidth,height=\textheight]{test}\page}
+\stoptext
