Formulas
The Projection Formulas use the image width for calculation. For proper projection placement, determine the image width
for the desired screen size. Use the Screen Formulas below to calculate all screen dimensions. Plug in the 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
D = Vertical distance between lens center and screen top
(screen bottom for desktop application)
Projection Formulas:
B = 0.258W
C(wide) = 1.4805W – 1.823
C(tele) = 1.7765W – 1.820
D = 0.118W
α(wide) = tan¯¹ (B/C(wide))
α(tele) = tan¯¹ (B/C(tele))
