If the screen width is 7 feet and the projector's throw ratio is 2.0 - 2.4:1 (because projectors have zoom lenses, they also have a range of throw ratios) then you can place your projector anywhere from 14 to 16.8 feet away from the screen.
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.or 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.
