I use 28x100 because it creates a nice sized and readable screen on a 17” monitor when using a resolution of 1024x768. It fills the screen nicely, but has a font that is large enough to easily read.

My personal preference is 28x110. This size fits nicely on 17" monitors with a resolution of 1024x768.

We chose to set the standard at 21 X 97. This will fill a screen when the resolution is set at 800 X 600. It gives us some extra screen real estate, particularly in the width where its most useful, but doesn't strain the eyes of our older employees.
