You could change Word's own document zooming to enlarge what you see on screen. For example, if you add the following two macros to Word's Normal template, most documents that you create or open will automatically zoom to fit the page width to the screen width (up to a max 150% - which you can change). The macro also sets the view to the Print Layout view and forces Word to display the rulers.

For Mac macro installation & usage instructions, see:

Code:
Private Sub Document_New()
Call Document_Open
End Sub
Private Sub Document_Open()

'Round down to nearest 10%
