Formulas

The Projection Formulas use the image width for calculation. Image height is the same for all aspect ratios, only horizontal image

size varies when using a 16:10 aspect ratio screen. 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 “W” for a 16:10 aspect ratio image

in the Projection Formulas.

Refer to the diagrams (page 5) and charts below for popular screen sizes 16:10 screens:

Definitions: 16:10 Screen Formulas:

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)

Projection Formulas:

B= 0.271W

C(wide) = 1.4477W – 1.823

C(tele) = 1.7386W – 1.820

D= -0.040W

α(wide) = tan¯¹ (B/C(wide))

α(tele) = tan¯¹ (B/C(tele))

Note: Tilting the front of the projector or down by more than 45° from level could reduce lamp life by up to 20%.
