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) × 0.0174 - 0.0471
maximum L (m) = (diagonal screen size in inches) × 0.0216 - 0.0442
minimum L (m) = (diagonal screen size in inches) × 0.0286 - 0.0540
maximum L (m) = (diagonal screen size in inches) × 0.0413 - 0.0498
minimum L (m) = (diagonal screen size in inches) × 0.0395 - 0.0745
maximum L (m) = (diagonal screen size in inches) × 0.0529 - 0.0734
minimum L (m) = (diagonal screen size in inches) × 0.0500 - 0.0800
maximum L (m) = (diagonal screen size in inches) × 0.0789 - 0.0792
minimum L (m) = (diagonal screen size in inches) × 0.0787 - 0.1351
maximum L (m) = (diagonal screen size in inches) × 0.1190 - 0.1346
minimum L (m) = (diagonal screen size in inches) × 0.1192 - 0.3017
maximum L (m) = (diagonal screen size in inches) × 0.1885 - 0.2991
(fixed focus) L (m) = (diagonal screen size in inches) × 0.0175 - 0.0476
