Projection distance formulas
Any other projection distance can be obtained according to the screen dimensions (m) using the following calculations.
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) = 1.3956 × SD(m) - 0.0241 = 1.5205 × SD(m) - 0.0241
Maximum distance (LT) = 1.6746 × SD(m) - 0.0242 = 1.8245 × SD(m) - 0.0242
