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) × 0.0201 – 0.0566
maximum L (m) = (diagonal screen size in inches) × 0.0241 – 0.0736
minimum L (m) = (diagonal screen size in inches) × 0.0284 – 0.0857
maximum L (m) = (diagonal screen size in inches) × 0.0367 – 0.1085
minimum L (m) = (diagonal screen size in inches) × 0.0364 – 0.0832
maximum L (m) = (diagonal screen size in inches) × 0.0528 – 0.1162
minimum L (m) = (diagonal screen size in inches) × 0.0524 – 0.1131
maximum L (m) = (diagonal screen size in inches) × 0.1017 – 0.1765
minimum L (m) = (diagonal screen size in inches) × 0.1004 – 0.1577
maximum L (m) = (diagonal screen size in inches) × 0.1601 – 0.1615
minimum L (m) = (diagonal screen size in inches) × 0.1595 – 0.3862
maximum L (m) = (diagonal screen size in inches) × 0.2989 – 0.3598
L (m) = (diagonal screen size in inches) × 0.0154 – 0.0713
