The most common question when come to screens is “what size should I get?”
This is governed by how far back the audience is sitting, if there are multiple rows of seating the centre row is normally used to establish screen size.
It is often suggested that the screen should be half the size of the sitting distance. So if the audience is 14ft away a 7ft wide screen would be ideal. However with the event of Full High Definition, all that extra clarity and detail means that there is no reason you shouldn’t go for a larger screen. 3D has also created a need for larger screens in relation to the sitting distance in order to greater fill the peripheral vision.
