Calculation of the projection distance
For a screen size different from the above, use the equation below to calculate the projection distance.
Aspect ratio 16:9
minimum
L (mm) = (diagonal screen size in inches) × 23.1 – 56.6
maximum
L (mm) = (diagonal screen size in inches) × 27.7 – 73.6
minimum
L (mm) = (diagonal screen size in inches) × 32.4 – 85.7
maximum
L (mm) = (diagonal screen size in inches) × 41.9 – 108.5
minimum
L (mm) = (diagonal screen size in inches) × 34.3 – 76.0
maximum
L (mm) = (diagonal screen size in inches) × 45.8 – 100.4
minimum
L (mm) = (diagonal screen size in inches) × 41.5 – 83.2
maximum
L (mm) = (diagonal screen size in inches) × 60.2 – 116.2
minimum
L (mm) = (diagonal screen size in inches) × 46.0 – 79.5
maximum
L (mm) = (diagonal screen size in inches) × 68.9 – 106.4
minimum
L (mm) = (diagonal screen size in inches) × 59.8 – 113.1
maximum
L (mm) = (diagonal screen size in inches) × 116.0 – 176.5
minimum
L (mm) = (diagonal screen size in inches) × 68.9 – 95.8
maximum
L (mm) = (diagonal screen size in inches) × 115.1 – 121.6
minimum
L (mm) = (diagonal screen size in inches) × 115.1 – 115.8
maximum
L (mm) = (diagonal screen size in inches) × 183.1 – 101.3
minimum
L (mm) = (diagonal screen size in inches) × 183.1 – 386.2
maximum
L (mm) = (diagonal screen size in inches) × 343.0 – 359.8
L (mm) = (diagonal screen size in inches) × 17.6 – 83.5
