maybe add a cropbox to the document, e. g. by hyperref:

\usepackage[..., pdfpagescrop={60 80 536 720}]{hyperref}

Then the text will still be put on the paper-size mediabox for correct
printing, but the reader (xpdf, acroread) will display only the cropped
area (with some added border if you want). These four dimensions lower
left x/y and upper right x/y [bp] you can calculate by various ways, e.
g. by putting your text into some box and measure its dimensions. Or by
two pdflatex runs: in the 1st run store the absolute lower left and
upper right corner positions on the page with \pdfsavepos, \pdflastxpos
and \pdflastypos into some .aux file for the 2nd run.
