The formula for picture size and projection distance

χ: Picture size (diag.) (in)

[Feet/inches]

L1 (ft) = (0.04314χ – 0.0546) / 0.3048

L2 (ft) = (0.03595χ – 0.0546) / 0.3048 H (in) = – 0.01807χ

[m/cm]

L1 (m) = 0.04314χ – 0.0546

L2 (m) = 0.03595χ – 0.0546

H (cm) = – 0.01807χ ⋅ 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.
