One of the big challenges in using Google Docs was editing documents big windows which would cause the writing canvas to stretch the entire browser width. On wide-screen displays, this often meant viewing entire paragraphs on just a line or two of the display. When the was printed out or sent to another medium where the width was sized down to something reasonable, you may be in for a surprise. Google introduced "Fixed Width Page View" which is very similar to Microsoft Word's Print Layout view. This brings Google Docs much closer to Microsoft Word. However there is still a small niggle but with a simple solution.

While Google Docs doesn't provide a simple way to zoom in and out, you can use the browsers zooming function to easily zoom in and out (use Ctrl + or Ctrl - in Firefox).
