Well, this doesn't quite work, because the atomic radius changes when you form a bond, and I don't feel like converting volumes to moles without my trusty TI-86 by my side, but neglecting everything except nitrogen and oxygen and taking a volume weighted average* of the narrowest assumed dimension, I get that air's average "thickness" is 7.06 x 10E-11 meters. If a ream of paper is 2 inches thick and contains 500 sheets with no gaps in between each one, then a sheet is about 1.02 * 10E-4 meters.
That makes the paper 1.44 million times as thick.
* Sources: Wikipedia.org and chemicool.com state the atmosphere is 78.084% N2 and 20.946% O2 by volume. The radii of atomic nitrogen and oxygen are 70 pm and 73 pm respectively.
