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 0.0303 - 0.044
maximum
L (m) = (diagonal screen size in inches) x 0.0364 - 0.044
Aspect ratio 16 : 9
minimum
L (m) = (diagonal screen size in inches) x 0.0331 - 0.044
maximum
L (m) = (diagonal screen size in inches) x 0.0397 - 0.044
NOTE:
Values shown are approximate.
