How to determine the throw distance between the mobile projector and the screen?

To determine the throw distance or how far back you need to set up the mobile projector from the wall or screen, first, you have to measure the horizontal width of your screen and multiply it to 1.3, which is the throw ratio of the mobile projector.

The following is an example on how to calculate the throw distance to maximize the available space you have.

8 feet (horizontal width of the screen) X 1.3 (throw ratio) = 10.4 feet (distance between the mobile projector and wall or screen)
