16:9 Screen Formulas:
W = H x 16/9
H = W x 9/16
Screen Diagonal = W x 18.358/16
Projection Formulas:
B (max) = 0.347W
B (min) = 0
C (wide) = 1.282W – 1.426
C (tele) = 2.202W – 1.375
D (max) = -0.065W
D (min) = 0.281W
α (wide) = tanˉ¹ (B/C(wide))
α (tele) = tanˉ¹ (B/C(tele))
Note: For screen sizes not indicated on the projection
tables, use the formulas on page 1.
