The formula for picture size and projection distance
L1 (ft) = 0.0302χ / 0.3048
L2 (ft) = 0.0455χ / 0.3048
H (in) = 0.034χ / 2.54
X: Picture size (diag.) (in)
L: Projection distance (m)
L1: Maximum projection distance (ft)
L2: Minimum projection distance (ft)
H: Distance from the lens centre to the bottom of the image (in)

The formula for picture size and projection distance
L1 (ft) = 0.0329χ / 0.3048
L2 (ft) = 0.04957χ / 0.3048
H (in) = –0.24459χ / 2.54

Note

• 

There is an error of ± 3% in the formula above.

• 

Values with a minus (–) sign indicate the distance of the lens centre below the bottom of the image.
