Just trying to re-size a .pdf to fit the cover of my new book?

Thanks, Keith

Not exactly certain what you're trying to do, but let's move this to the Acrobat forum for you.

Do you want to scale the PDF page to a specific size?

This tool will resize pages:

It's intended to be used to tile pages, but if you specify the tile as 1x1, then you can specify an exact output size (proportional).
