There are two key factors for selecting the right display size for K-12 classrooms. The first is the potential size of the display. The second is the distance from which the students are viewing the display. Both factors are determined by the classroom space.
In audio visual (AV) installations, the common standard used for determining screen size known as the 4/6/8 rule. This rule establishes that ideal viewing distance, in correlation with room size, should be four, six or eight times the height of the screen for analytical viewing, basic viewing and passive viewing. The advantage of applying this rule in classrooms is that the distances can be measured according to particular activities needing use of the screen. More information on this rule is available in the whitepaper below.
There are typically three classroom configurations—square, wide and deep. The general size for the classrooms is based on the California recommended classroom size of 960 square feet.
