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.
This question is very confusing. Throw is a term that tells a person what the ratio of how far back to how big the screen is. The RS-1 is pretty long throw(1.4-2.8). the upper end is 2.8 meaning you can put the projector as far back as 2.8 screen widths.
