The formula for screen size and projection distance
y | = (0.0203x 0.0561) 3.28 | x: Screen size (diag.) (inches) |
z1 | (Upper) = 0.245x | y: Projection distance (L) (feet) |
z2 | (Lower) = 0.212x | 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.
