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) × 0.0217 – 0.0566

maximum

L (m) = (diagonal screen size in inches) × 0.0260 – 0.0736

minimum

L (m) = (diagonal screen size in inches) × 0.0304 – 0.0857

maximum

L (m) = (diagonal screen size in inches) × 0.0393 – 0.1085

minimum

L (m) = (diagonal screen size in inches) × 0.0389 – 0.0832

maximum

L (m) = (diagonal screen size in inches) × 0.0566 – 0.1162

minimum

L (m) = (diagonal screen size in inches) × 0.0562 – 0.1131

maximum

L (m) = (diagonal screen size in inches) × 0.1090 – 0.1765

minimum

L (m) = (diagonal screen size in inches) × 0.1076 – 0.1577

maximum

L (m) = (diagonal screen size in inches) × 0.1715 – 0.1615

minimum

L (m) = (diagonal screen size in inches) × 0.1720 – 0.3862

maximum

L (m) = (diagonal screen size in inches) × 0.3222 – 0.3598

L (m) = (diagonal screen size in inches) × 0.0165 – 0.0713
