But if you are reading a PDF which you cannot convert to EPUB because the PDF has a complex page layout (diagrams etc.) you are at present stuck with the waste space at the bottom PLUS waste space at both sides since the ratio on a PDF page is fixed.
I described this on another post, referring to this discussion there:

I can't believe that this is so hard to make optional.
