Notes
• For screen sizes not indicated in the projection charts, use the formulas below.
• The ceiling must be strong enough to support the projector and the installation must be in accordance with any local
building codes.
• 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 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 for “W” in the
Projection Formulas.
Refer to the diagrams and charts for popular screen sizes on page 2.
Definitions: 16:9 Screen Formulas:
W = Image Width W = H x 16/9
H = Image Height (Size) H = W x 9/16
B = Vertical distance between lens center and screen center Screen Diagonal = W x 18.35756/16
C = Throw distance
Projection Formulas:
B(min) = 0.1877W
B(max) = 0.4710W
C(wide) = 1.6695W – 1.913
C(tele) = 1.9801W – 1.883
α(wide) = tan
α(tele) = tan
Note: Factory preset is B(max)/maximum lens shift.
