The formula for picture size and projection distance

χ: Picture size (diag.) (in)

[Feet, inches]

L1 (ft) = (0.0364χ – 0.06) / 0.3048

L2 (ft) = (0.0434χ – 0.06) / 0.3048 H (in) = – 0.0158χ

[m, cm]

L1 (m) = 0.0364χ – 0.06

L2 (m) = 0.0434χ – 0.06

H (cm) = – 0.0158χ ⋅ 2.54

Note

•There may be an error of ± 3% in the above values.

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