The formula for picture size and projection distance

L1 (ft) = (0.0472X – 0.0517) / 0.3048

L2 (ft) = (0.0367X – 0.0529) / 0.3048 H (in) = (0.1499X – 0.0064) / 2.54

X: Picture size (diag.) (in)

L: Projection distance (ft)

L1: Maximum projection distance (ft)

L2: Minimum projection distance (ft)

H:Distance from the lens center to the bottom of the image (in)

The formula for picture size and projection distance

L1 (ft) = (0.0514X – 0.0516) / 0.3048

L2 (ft) = (0.04X – 0.0523) / 0.3048 H (in) = (– 0.0422X + 0.0018) / 2.54

Note

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

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