Notes
ƒ
For screen sizes not indicated on the projection tables, use the formulas below.
If the figures on the tables do not match the results of formulas, use the figures in the table.
All calculations are based on a 4:3 aspect ratio.

Distances are in inches, for millimeters multiply by 25.4.
Distances may vary ±5%.
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
4:3 Screen Formulas:
W = H x 4/3
H = Image Height (size)
H = W x 3/4
B = Vertical distance between lens center and screen center
C = Throw distance
Screen Diagonal = W x 5/4
D = Vertical distance between lens center and screen top
(screen bottom for desktop application)
Projection Formulas:
B = 0.266W
C (wide) = 1.475W – 1.176
C (tele) = 1.773W – 1.173
D = 0.108W
α (wide) = tan¯¹ (B/C(wide))
α (tele) = tan¯¹ (B/C(tele))
