Thank you very much Aditya for looking into this. But I still have the same
baseline grid offset problem. Interestingly, when I remove the columns, the
text shifts downwards by two lines.
My code:
\definemeasure[xheight][0.1in]
\definemeasure[base][3\measured{xheight}]
% Since all distances are in terms of base units, specify the paper size in
those
% terms as well.
\definepapersize[slide][width=26\measured{base},height=20\measured{base}]
\setuppapersize[slide]
\setupinterlinespace[line=\measure{base}]
\setuplayout
[
topspace=2\measured{base},
header=\zeropoint,
headerdistance=\zeropoint,
height=middle, % Space for 20-4=16 lines
footerdistance=\zeropoint,
footer=\zeropoint,
bottomspace=2\measured{base},
%
cutspace=2\measured{base},
leftmargin=\zeropoint,
leftmargindistance=\zeropoint,
width=middle, % space for 26-4=22 col
rightmargindistance=\zeropoint,
rightmargin=\zeropoint,
backspace=2\measured{base}
grid=yes,
]
\showframe
\showgrid
\starttext
\input tufte
\stoptext
I'm attaching the pdf output.
