The formula for picture size and projection distance

χ: Picture size (diag.) (in)

[Feet, inches]

L1 (ft) = (0.0472χ – 0.0517) / 0.3048

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

[m, cm]

L1 (m) = 0.0472χ – 0.0517

L2 (m) = 0.0367χ – 0.0529

H (cm) = 0.1499χ – 0.0064

The formula for picture size and projection distance

χ: Picture size (diag.) (in)

[Feet, inches]

L1 (ft) = (0.0514χ – 0.0516) / 0.3048

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

[m, cm]

L1 (m) = 0.0514χ – 0.0516

L2 (m) = 0.04χ – 0.0523

H (cm) = –0.0422χ+ 0.0018

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.
