The most common dilemma when buying. The distance from the screen to the back row decides – not the size of the wall.

A simple rule
Measure the distance from the display wall to the back row. Up to 5 m, 65 inch is enough; up to 6.5 m, choose 75 inch; beyond that, 86 inch. If in doubt, choose the larger screen: students in the back row must be able to read handwriting on the board.
What about price?
The difference between 65 and 75 inch is usually smaller than between 75 and 86 inch. That is why 75 inch is the most common choice for schools. Compare models: 65 inch, 75 inch, 86 inch.
Frequently asked questions
Is 65 inch enough for a classroom?
For a small classroom where the back row sits up to about 5 m from the screen – yes. In a typical classroom, 75 inch works better.
