Selecting the right type and size of screen is important for making sure that your message is effectively presented to the target audience. Furthermore, one needs to consider the environment in which the screen will be placed and the length of time during which it will be operational.
When determining the screen's optimal size, one needs to consider the distance between the viewer and the screen for best viewing results. In canteens, screens will typically be smaller than those placed in production areas, where an abundance of information, figures and graphs are often displayed. The maximum viewing distance (in meters) can be calculated by dividing the screen size (in inches) by 10. For example, the maximum viewing distance for an 80"screen is 8 meters (80 divided by 10).
