PDF Report page size

I've been designing the PDF report to include 2 columns of data. Although it shows all the fields are within the same page, once you download the PDF it overflows 1 row onto the next page. I've tried to change the size of the font but that didn't adjust the spacing at all.

Is there any way to change the page size perhaps? Or some other way to make all of the text fit in the actual PDF?

Changing the font size does not adjust the container size for each element:

To make the sizing smaller, it requires adjusting the sizing of each element.  There is a minimum height for each element.  The height cannot be reduced and further at this time. 

It is possible, as you have already seen, to create a 4 column report:

Short of removing fields or adding more columns, it is not possible to further reduce the spacing.
