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) × 0.0201 – 0.0566

maximum

L (m) = (diagonal screen size in inches) × 0.0241 – 0.0736

minimum

L (m) = (diagonal screen size in inches) × 0.0284 – 0.0857

maximum

L (m) = (diagonal screen size in inches) × 0.0367 – 0.1085

minimum

L (m) = (diagonal screen size in inches) × 0.0364 – 0.0832

maximum

L (m) = (diagonal screen size in inches) × 0.0528 – 0.1162

minimum

L (m) = (diagonal screen size in inches) × 0.0524 – 0.1131

maximum

L (m) = (diagonal screen size in inches) × 0.1017 – 0.1765

minimum

L (m) = (diagonal screen size in inches) × 0.1004 – 0.1577

maximum

L (m) = (diagonal screen size in inches) × 0.1601 – 0.1615

minimum

L (m) = (diagonal screen size in inches) × 0.1595 – 0.3862

maximum

L (m) = (diagonal screen size in inches) × 0.2989 – 0.3598

L (m) = (diagonal screen size in inches) × 0.0154 – 0.0713
