Projection distance for 16:9 aspect ratio screen
Unit: meters
Unit: feet
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
L (m) = (diagonal screen size in inches) × 0.0107 – 0.0389
Aspect ratio 16 : 9
L (m) = (diagonal screen size in inches) × 0.0117 – 0.0395
NOTE: Distances calculated with the above equations will include a slight error.
