This question was sent in by Karen from Kansas:

Any guidelines on the size of the LCD in relation to the distance from the people?

The usual guideline is 1.5 to 2 times the width of the screen. There are others, including Joel Silver of the Imaging Science Foundation that say buy as big as you want as long as the purchase makes you happy.

I should note that he does recommend at the same guidelines, but when he addresses custom installers that take his ISF classes he acknowledges the customer’s input in wanting the biggest possible screen.
