Throw distance x width of screen in inches = distance from screen to projector lens. Throw distance is the distance from the screen to the projector. For example, if your screen is 87â wide and the throw distance of your projector is 1.3, the projector should be 113â (87x1.3=113â) from the screen. Remember to measure from the center of the projectorâs lens straight to the screen, like the above image shows. For most people, your projector will list a throw distance, or throw ratio in this case, of something like 1.5-2.25. The wider the throw ratio, the more wiggle room you have in placing your projector.
