Calculation of the projection distance
For a screen size different from the above, use the equation below to calculate the projection distance.
• Distances calculated with the above equations will include a slight error.
minimum L (m) = (diagonal screen size in inches) × 0.0183 - 0.0471
maximum L (m) = (diagonal screen size in inches) × 0.0227 - 0.0442
minimum L (m) = (diagonal screen size in inches) × 0.0300 - 0.0540
maximum L (m) = (diagonal screen size in inches) × 0.0433 - 0.0498
minimum L (m) = (diagonal screen size in inches) × 0.0398 - 0.0746
maximum L (m) = (diagonal screen size in inches) × 0.0555 - 0.0725
minimum L (m) = (diagonal screen size in inches) × 0.0524 - 0.0800
maximum L (m) = (diagonal screen size in inches) × 0.0828 - 0.0792
minimum L (m) = (diagonal screen size in inches) × 0.0827 - 0.1351
maximum L (m) = (diagonal screen size in inches) × 0.1249 - 0.1346
minimum L (m) = (diagonal screen size in inches) × 0.1251 - 0.3017
maximum L (m) = (diagonal screen size in inches) × 0.1979 - 0.2991
(fixed focus) L (m) = (diagonal screen size in inches) × 0.0184 - 0.0476
