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) × 0.0104 – 0.0339
Aspect ratio 16:9
L (m) = (diagonal screen size in inches) × 0.0106 – 0.0339
Aspect ratio 4:3
L (m) = (diagonal screen size in inches) × 0.0117 – 0.0339
NOTE:
Distances calculated with the above equations will include a slight error.
