The formula for picture size and projection distance
[m/cm]
L1 (m) = 0.03755χ
L2 (m) = 0.04507χ
H (cm) = –0.03209χ
[Feet/inches]
L1 (ft) = 0.03755χ / 0.3048
L2 (ft) = 0.04507χ / 0.3048

Note
• Allow a margin of error in the value in the diagrams above.
• When the distance from the lens center to the bottom of the image [H] is a negative number, this indicates
that the bottom of the image is below the lens center.
• See page
about projection distance [L] and distance from the lens center to the bottom of the image [H].
