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
L (m) = (diagonal screen size in inches) × 0.01123
Aspect ratio 16:9
L (m) = (diagonal screen size in inches) × 0.01153
NOTE:
Distances calculated with the above equations will include a slight error.
