PDF export makes use of latex so you need to provide latex
customisations.  The easiest (IMO) way to modify margins and paper
size is through the geometry package, as in:

#+latex_header: \usepackage[margin=5cm]{geometry}

in the preamble of your org file.

See the documentation for the latex geometry package (on the web etc)
for full details of everything you can modify!
