Any other projection distance can be obtained according to the screen dimensions (m) using the following
calculations.
The distance is shown in units of meters. (The calculated distance may contain a certain error.)
If the screen dimensions are written as “SD",
For 4:3 aspect ratio For 16:9 aspect ratio
Screen height (SH) = SD (m) × 0.6 = SD (m) × 0.490
Screen width (SW) = SD (m) × 0.8 = SD (m) × 0.872
Minimum distance (LW) = 1.2332 × SD (m) – 0.0546 = 1.3425 × SD (m) – 0.0546
Maximum distance (LT) = 2.4567 × SD (m) – 0.0408 = 2.6771 × SD (m) – 0.0408
