Increase Background Size in Acrobat DC

Hi, I would like to take notes (freehand) on my tablet PC with a stylus. The problem is, there is not enough space sometimes. Is there any way to increase the grey background for a pdf? Zooming out to get more space is not good, because then at normal view, the writing is too large.

Basically, I want to increase the width of the document, this way I can scroll side to side for more space to write.
