You should also consider
• Ceiling height
Take the ceiling height into account in your calculation as this is often a limiting factor.
• Comfortable viewing height
For professional and educational applications the distance between the floor and the viewing area of a projection screen
should be approximately 125 cm to make sure those sitting in the rear of the audience can see the projection. Depending on
the height of the ceiling, this may require additional black drop if the projection screen is ceiling mounted. For home
entertainment applications this distance should be between 60 and 90 cm.
• Comfortable viewing distance
For professional and educational applications the first row of seats should be approximately 1.5 screen heights away. For
home entertainment applications the first row of seats should be approximately 2 screen heights away
Always consider the most demanding usage of your projection when determining the size Although a flat panel display may
seem a good option for a smaller size presentation area, in most cases these are actually too small. If the rules of thumb are
applied often a larger projection screen should be specified to make sure the audience can see the necessary level of detail
comfortably.
