Calculation of the projection distance

For a screen size different from the above, use the equation below to calculate the projection distance.

Aspect ratio 4 : 3

minimum L (m) = (diagonal screen size in inches) x 0.0298 - 0.037
maximum L (m) = (diagonal screen size in inches) x 0.0361 - 0.037

Aspect ratio 16 : 9

minimum L (m) = (diagonal screen size in inches) x 0.0325 - 0.037
maximum L (m) = (diagonal screen size in inches) x 0.0393 - 0.037

NOTE:
Values shown are approximate.
