Projection dimensions calculation methods
If the screen size (diagonal) is SD (m), then the following formula is used to
calculate the projection distance for the wide lens position (LW) and the
projection distance for the telephoto lens position (LT).
4:3
SW
Minimum Projection Distance
Maximum Projection Distance
For 16:9 aspect ratios, the following formula can be used to calculate the
projection distance.
Minimum Projection Distance
Maximum Projection Distance
*The values obtained from the formulas above are approximate.
LW/LT
LW=0.0407xSD/0.0254-0.080
LT=0.0538xSD/0.0254-0.0774
LW=0.0443xSD/0.0254-0.080
LT=0.0586xSD/0.0254-0.0774
