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
	SH
	H1
LW/LT	SW
Minimum Projection Distance	LW=0.030xSD/0.0254-0.044
Maximum Projection Distance	LT=0.036xSD/0.0254-0.044

For 16:9 aspect ratios, the following formula can be used to calculate the projection distance.

Minimum Projection Distance	LW=0.033xSD/0.0254-0.044
Maximum Projection Distance	LT=0.040xSD/0.0254-0.044

*The values obtained from the formulas above are approximate.
