The formula for screen size and projection distance
y1(Max.) = (0.1275x0.1593)3.28
y2(Min.) = (0.0911x0.1592)3.28
z1(Upper) = 0.245x

x: Screen size (diag.) (inches)
y: Projection distance (L) (feet)
z: Lens center to the lower edge of the screen (H) (inches)
•There is an error of 3% in the formula above.
•Values with a minus () sign indicate the distance of the lens center below the bottom of the screen.
