By default, MS Word doesn't show the Text Boundaries (where the margins are).
Here's a little macro which gives you the ability to turn on/off the Text Boundaries:
Sub Toggle_Text_Boundaries()
'
' Text_Boundaries Macro
' Turn Text Boundaries on/off
'
If (ActiveWindow.View.ShowTextBoundaries = True) Then
ActiveWindow.View.ShowTextBoundaries = False
ElseIf (ActiveWindow.View.ShowTextBoundaries = False) Then
ActiveWindow.View.ShowTextBoundaries = True
End If
End Sub
Or this one, which is shorter:
Sub Toggle_Text_Boundaries()
ActiveWindow.View.ShowTextBoundaries = _
Not ActiveWindow.View.ShowTextBoundaries
End Sub
Please note that Word 2007 has full page text boundaries, which is what you'd expect.
Word 2013 has paragraph text boundaries, which is less helpful. Sadly, this behavior is hard-coded and cannot be changed.
