of the screen. For example, if the screen width (W) is 2.4 meters and the projector lens has a throw ratio (L) of
0.99:1, then the throw distance (D) will be 2.38 meters.
Calculation: 2.4 x 0.99 = 2.38
The following graphs illustrate the image size (W) and projection distance (D) for each of the projector lenses.
Tolerances are typically +/- 5% due to optical (lens) variation.
