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(m) = (diagonal screen size in inches) x 0.035 - 0.037
maximum L (m) = (diagonal screen size in inches) x 0.042 - 0.036
Aspect ratio 16 : 9
minimum L (m) = (diagonal screen size in inches) x 0.038 - 0.037
maximum L (m) = (diagonal screen size in inches) x 0.046 - 0.037
NOTE:
Values shown are approximate.
