Calculation of the projection distance
For a screen size different from the above, use the equation below to calculate the projection distance.
Aspect ratio 16 : 10
minimum L (m) = (diagonal screen size in inches) x 0.0289 - 0.046
maximum L (m) = (diagonal screen size in inches) x 0.0576 - 0.061
Aspect ratio 16 : 9
minimum L (m) = (diagonal screen size in inches) x 0.0297 - 0.045
maximum L (m) = (diagonal screen size in inches) x 0.0592 - 0.061
NOTE:
Distances calculated with the above equations will include a slight error.
