Not for hundreds. I originally suggested it for when there is an edge 
case that needs manual checking, or when an automated decision is 

One tool that did occur to me is pdfcrop, but you'd probably need to 
remove the running header and footer to get to the text body.

However, if there is some commonality between them, you could aotumate 
ImageMagick to cut off the running header and footer, and then see if a 
crop of the remainder yielded a rectangle of the specified size, plus or 
minus some tolerance.

One conference I attended requested all the papers in a specified 
format, permitted one cycle of correction, and if it didn't fir the 
pattern after that, it didn't get into the Proceedings. All authors were 
warned about this at submission time, and signed a release declaring 
they understood and accepted this. They dropped 10% of the papers this 
way, and saved themselves weeks of fruitless argument with arrogant 
authors who believe THEY should be a special case :-)
