It's one robust way to make big posters with pdftex. Just do the poster
layout on a smaller design page (e. g. 250mm * 350mm, maybe multi
columns, grid) where the 10/11/12pt fonts (even math) work right
natively without any font size tuning. Then at the document begin: 1.
Calculate all page dimensions non-true, 2. set \mag, and 3. reset page
dimensions to true dimens --- and you get a big poster, with fonts
correctly scaled. One-file/one-step process, no PDF embedding step for
ximage magnification required. Also get a small handout version fitting
to A4, if \mag < 1000. Even with clickable links, which is not yet
possible with pdfximage (pdfpages package)!

Alternative would be poster macro packages, where all fonts are scaled
in the macro package relative to the final poster size, IMHO not
flexible for new fonts, much more work than just let pdftex recalculate
a few page related dimensions.
