The 5 page threshold applies to legal bond paper size only.
For a broadsheet (which has many columns and tantamount to several legal bond paper pages), I will have to look at it first so I can make an assessment.
I would only be retyping the words but not copy the graphics and the way the layouts have been done on your doc.
I would only retype wholesome contents.
5-PAGE retype gig
PDF documents and handwritten notes or any page that is not beyond the size of a regular bond paper.
