Formulas

The Projection Formulas use the image width for calculation. For proper pro jection 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

W = Image Width W = H x 16/10
H = Image Height (size) H = W x 10/16
B = Vertical distance between lens center and screen center Screen Diagonal = W x 18.868/16
C = Throw distance
D = Vertical distance between lens center and screen top
(screen bottom for desktop application)

α = Throw Angle

Projection Formulas:
B = 0.375W
C = 0.48W (wide)
D = 0.0625W
