Why not just use the dpi parameter when rendering?

I'm sure this question has been asked before but I wasn't on the list when it 
was.  I have PDFs that I need to convert to images.  Most are 8.5x11.  Some are 
8.5 x 3.5.  My problem is figuring out the resolution when I save them as 
200dpi tiff images.  I made some assumptions that held true until I encountered 
PDFs that deviated from the those assumptions.  Although I can assume all PDFs 
are 8.5 inch wide and therefore I can deduce the resolution based of the width 
of the actually page I don't want to assume anything but calculate the 
resolution base on what I can get from the PDF structure itself.
