Calculation of the projection distance
For a screen size different from the above, use the equation below to calculate the projection distance.
Aspect ratio 4:3
minimum
L (mm) = (diagonal screen size in inches) × 20.7 – 56.6
maximum
L (mm) = (diagonal screen size in inches) × 24.8 – 73.6
minimum
L (mm) = (diagonal screen size in inches) × 29.0 – 85.7
maximum
L (mm) = (diagonal screen size in inches) × 37.5 – 108.5
minimum
L (mm) = (diagonal screen size in inches) × 30.7 – 76.0
maximum
L (mm) = (diagonal screen size in inches) × 41.0 – 100.4
minimum
L (mm) = (diagonal screen size in inches) × 37.1 – 83.2
maximum
L (mm) = (diagonal screen size in inches) × 54.0 – 116.2
minimum
L (mm) = (diagonal screen size in inches) × 41.2 – 79.5
maximum
L (mm) = (diagonal screen size in inches) × 61.7 – 106.4
minimum
L (mm) = (diagonal screen size in inches) × 53.6 – 113.1
maximum
L (mm) = (diagonal screen size in inches) × 103.9 – 176.5
minimum
L (mm) = (diagonal screen size in inches) × 61.7 – 95.8
maximum
L (mm) = (diagonal screen size in inches) × 103.1 – 121.6
minimum
L (mm) = (diagonal screen size in inches) × 103.1 – 115.8
maximum
L (mm) = (diagonal screen size in inches) × 163.9 – 101.3
minimum
L (mm) = (diagonal screen size in inches) × 164.0 – 386.2
maximum
L (mm) = (diagonal screen size in inches) × 307.2 – 359.8
L (mm) = (diagonal screen size in inches) × 15.8 – 83.5
