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. The ceiling must be strong enough to support the LCD projector and the installation must be in accordance with any local
building codes.
All calculations are based on 4:3 aspect ratio.
Distances are in inches, for millimeters multiply by 25.4.
Distances may vary ±5%.
Formulas
Units: Inches (for millimeters multiply final number by 25.4)
Definitions:
H = Horizontal Screen Width (4:3) V = Vertical Screen Height (4:3)
B = Vertical distance between lens center and screen center C = Throw distance D = Vertical distance between lens center and screen top (screen bottom for desktop application) α = Throw Angle
Projection Formulas:
B = 0.3193H H = Screen Diagonal x 4/5
C (wide) = 1.2996H 2.325 V = Screen Diagonal x 3/5
C (tele) = 1.5985H 2.325 Screen Diagonal = H x 5/4
D = 0.0557H
α (wide) = tan
α (tele) = tan
