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
A (m) = (diagonal screen size in inches) × 0.00450 – 0.0400
Aspect ratio 16:9
A (m) = (diagonal screen size in inches) × 0.00462 – 0.0400
NOTE:
Distances calculated with the above equations will include a slight error.
