Step 2. Screen Size
The best performance is achieved by determining the correct size. Ideally, the screen size should occupy a minimum of a 30° field of view for the audience.
Determine the optimum screen size based on room dimensions, planned audience seating size and arrangement. Remember: fit the screen to the audience - not to the projector.
The rule of thumb for Home Theater is to use a screen height that is approximately one third the distance from the screen to the audience seating. Screen placement should be determined according to the sightlines of the installation. This will allow all members of the audience to see the screen.
For larger or more general venues, screen height should be approximately equal to 1/6 the distance from the screen to the last row of seats, allowing text to be read and detail to be seen in the projected image. Ideally, the first row of seats should be approximately two screen heights away.
The bottom of the screen should be a minimum of 4 feet above the audience floor, allowing those seated toward the rear of the audience to see the screen. This may require additional screen "drop" for ceiling hung screens.
