Formulas
The Projection Formulas use the image width for calculation. For proper projector placement, determine the image width for a
desired screen size. Use the Screen Formulas below to calculate all screen dimensions. Plug in the image width for "W" in the
Projection Formulas.
Refer to the diagrams and charts for popular screen sizes on page 2.
Definitions:
W = Image Width
H = Image Height (Size)
B = Vertical distance between lens center and screen center
C = Throw distance
Projection Formulas:
B(min) = 0.1877W
B(max) = 0.4710W
C(wide) = 1.6695W – 1.913
C(tele) = 1.9801W – 1.883
