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
minimum
L (m) = (diagonal screen size in inches) × 0.0257 – 0.0294
maximum
L (m) = (diagonal screen size in inches) × 0.0414 – 0.0319
Aspect ratio 16:9
minimum
L (m) = (diagonal screen size in inches) × 0.0264 – 0.0294
maximum
L (m) = (diagonal screen size in inches) × 0.0426 – 0.0319
NOTE:
Distances calculated with the above equations will include a slight error.

Projection distance for 16:9 aspect ratio screen
unit: meters (feet)
NOTE:
• The value for L (distance to screen) varies slightly depending on the zoom lens characteristics.
• At the shortest projection distance, the zoom lens characteristics may cause slight image distortion.
