On the LT150's throw distance sheet, it states the "Throw Ratio" as 1.64 - 1.63:1, "dependent on screen size and focus setting". It later gives a more exact equation for determing the throw distance. Specifically, it's: 1.6288 x Width - 0.5157, which pretty much looks like the previously stated "Throw Ratio".
Is "Throw Ratio" a relatively universal term that other projector manufacturers use? If so, is it always a number that is to be multiplied with the image width, or do some manufacturers intend it to be used with height or diagonal measurements? Is there an easy way to obtain the throw ratio/distance information for most/all projectors out there or would this require getting it from the instruction manuals?
