Formulas

Units: Inches (for millimeters multiply final number by 25.4)

Definitions:

H = Horizontal Screen Width (4:3)

Screen Formulas (4:3):

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
