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).

For 16:9 aspect ratios, the following formula can be used to calculate the
projection distance.
LW=30.919xSD/0.0254-42.514
LT=36.766xSD/0.0254-42.233
Minimum Projection Distance (mm)
Maximum Projection Distance (mm)
LW=33.902xSD/0.0254-42.524
LT=40.359xSD/0.0254-42.519
Minimum Projection Distance (mm)
Maximum Projection Distance (mm)
*The values obtained from the formulas above are approximate.
