Here is a posting I recently made to the Acrobat "Editing and Exporting PDFs" forum:

As it turns out, Acrobat Pro XI is supposed to be able to do this, but as I stated offline to try76, "... I experimented with increasing the white space around pages (to 8.5 x 11.0) in XI. The single-column test page I sent you is from a 9-page, mostly three-column document, and when I use the Cropping Tool while attempting to do this, there is one lone (3-column) page that refuses to re-size - whether I try to do it individually or on the whole document...."

All of these pages came from exactly the same source (i.e., a single .TIF scan series, followed by export via ABBYY FineReader Pro 14), so there should be no differences in them - yet Acrobat fails to perform. AFAIK, this is yet another bug, rather than some peculiarity injust that one page.

In the meantime, this same putative "cropping" feature (cough!) in Acrobat Pro XI should be able to process the desired range of pages within the 200-page (4.25 w x 7.0 h) file that I mentioned in my initial forum posting on this subject (above), but when I try it, any number of pages, scattered throughout the document, do not respond to the command.

I already own a full license for ABBYY FineReader 14, which is fully capable of exporting documents having whatever standard or custom page size I choose., but it is somewhat of a PITA having to drag a file like this into FineReader. This risks destruction of front- and back-matter page numbering that was painstakingly created within Acrobat - after which I then have to drag it back into Acrobat for clean-up of the page-numbering mess.
