For a screen size different from the above, use the equation below to calculate the projection distance.
NOTE:
Distances calculated with the above equations will include a slight error.
Projection distance for 16:9 aspect ratio screen
NOTE:

• At the shortest projection distance, the zoom lens characteristics may cause slight image distortion.
Projection distance for 4:3 aspect ratio screen

• At the shortest projection distance, the zoom lens characteristics may cause slight image distortion.
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
