The formula for screen size and projection distance

Y1	(Max.) = 0.15180x	x : Screen size (in)
Y2	(Min.) = 0.12057x	y : Projection distance (ft)
Z1	(Upper) = 0.00817x	z : Distance from the lens center to the
Z2	(Lower) = -0.03268x	lower edge of the image (in)

When using a normal screen (4:3)

In case of setting the 16:9 picture to the full horizontal width of the 4:3 screen.
