So instead of specifying the textwidth, specify the backspace and 
cutspace and let context figure out the textwidth...

\setuplayout
   [width=middle,
    location=middle,
    backspace=2.5cm,
    cutspace=2.5cm,
    marking=on]

The following works fine for me....

\definepapersize[argento][width=20cm,height=28cm]
\setuppapersize[argento][A3]
\setuppagenumbering[alternative=doublesided,location=]
\setuplayout
   [width=middle,
    location=middle,
    backspace=2.5cm,
    cutspace=2.5cm,
    marking=on]

\showframe
\setupheadertexts[chapter][pagenumber]

\starttext

\chapter{Two Columns}
\startcolumns[n=2, balance=yes,distance=8mm]
\dorecurse{6}{\input knuth \endgraf}
\stopcolumns

\chapter{Three Columns}
\startcolumns[n=3, balance=yes,distance=5mm]
\dorecurse{6}{\input knuth \endgraf}
\stopcolumns

\stoptext
