The first thing context does is to check the value of width:
(the width of the textarea is stored in \makeupwidth, not \textwidth)

1. width=middle

if cutspace=0pt then cutspace=backspace endif

makeupwidth = paperwidth - backspace - cutspace


2. width=fit

when i look at the source i don't know if anyone want this setting because
very complicated and the calculation is

makeupwidth = paperwidth - (backspace - leftmargin - leftmargindistance - leftedge - ...) - (cutspace - rightmargin - ...)


3. width=<dimen>

makeupwidth = <dimen>


Example:

\definelayout[1][backspace=4cm,width=12cm]
\definelayout[2][backspace=5cm,cutspace=7cm,width=middle]
\definelayout[3][backspace=3cm,cutspace=0pt,width=middle]
\definelayout[4][backspace=4cm,width=fit]
\definelayout[5][backspace=4cm,leftmargin=3cm,width=fit]
\definelayout[6][backspace=4cm,leftmargin=4cm,width=fit]
\definelayout[7][backspace=4cm,leftmargin=2cm,width=fit]
\definelayout[8][backspace=4cm,leftmargin=2cm,rightmargin=3cm,width=fit]
\definelayout[9][backspace=4cm,leftmargin=2cm,rightmargin=4cm,width=fit]
\definelayout[10][backspace=4cm,leftmargin=2cm,rightmargin=2cm,width=fit]
