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.
The throw distance of your projector will be listed in the manual. If it only lists a single number, like â1.3â, then your projector does not have an optical zoom adjustment. This means that the only way to adjust the size of the image is to physically move the projector closer or farther away from the screen.
