Front Projection Height Calculator
This handy calculator helps you determine what height to put your projectors at so that they still have enough lens shift to fill the screen, but are not covering part of your image. Added bonus: you can also use it to calculate heights for anything hanging in front of the screen to make sure they don't block the view.
