Notes
For screen sizes not indicated on the projection charts, 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 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. Image width is the same for all aspect ratios, only vertical image size
varies. For proper projector placement, determine the image width for a desired screen size. Use the Screen Formulas below to
calculate all screen dimensions.
Plug the screen width in for “W” in the Projection Formulas.
Refer to the diagrams and charts for popular screen sizes on page 2 and 3.
Definitions:
4:3 Screen Formulas:
W
= Screen width
W
= H x 4/3
H
= Screen height
H
= W x 3/4
A
= Distance between projector cabinet and screen
Screen Diagonal
= W x 5/4
B
= Vertical distance between projector foot and screen center
C
= Throw distance
16:9 Screen Formulas:
D
= Vertical distance between projector foot and screen bottom
W
= H x 16/9
(screen top for ceiling mounted application)
H
= W x 9/16
Screen Diagonal
= W x 18.868/16
Projection Formulas:
A
= C-13.48
B
= 0.631W
C
= 0.377W
D
= 0.256W
