The exact way would be to read the LaTeX class and figure out what
dimensions are being used there. The approximate way would be to
visually compare the output of LaTeX and ConTeXt.

Or take Adobe Acrobat and use measuring tool, or compare visually
(aligning two documents in pdf viewer). If you print out the material
there's always a chance that printer won't align the edges properly.

The third option is to use the following in LaTeX to figure out what
dimensions are being used in LaTeX, compare that with figure in The
Not So Short Introduction to LaTeX and then use these numbers in
ConTeXt (properly adjusted for the differences):

hoffset=\the\hoffset\par
oddsidemargin=\the\oddsidemargin\par
marginparwidth=\the\marginparwidth\par
textwidth=\the\textwidth\par

But after I have managed to guess somehow that the horizontal
dimensions were matching
	[backspace=\dimexpr 1in+31pt\relax
	 width=\dimexpr 390pt\relax,
in latex,12pt (but for some unknow reason hyphenation in ConTeXt was
off, or at least at different penalty values, so I didn't manage to
compare the line breaks) ... I realized that margins change if you try
to use
    \documentclass[10pt,a4paper]{article}
instead of 12pt, so one would need to account for that change as well.
