Setting Up14

If you do not want to use the distance table, you can use the following equations to help

determine where to install the projector relative to the screen.

Image size relative to distance from the screen

Image size (diagonal) Image size (width) Distance (lens to screen)

(inches) (meters) (inches) (meters) (feet, inches) (meters)

40 1.0 32 0.8 5' 4" to 6' 2" 1.6 to 1.9

60 1.5 48 1.2 8' 0" to 9' 2" 2.4 to 2.8

80 2.0 64 1.6 10' 8" to 12' 3" 3.3 to 3.7

100 2.5 80 2.0 13' 4" to 15' 4" 4.1 to 4.7

120 3.0 96 2.4 16' 0" to 18' 5" 4.9 to 5.6

150 3.8 120 3.0 20' 0" to 23' 0" 6.1 to 7.0

180 4.6 144 3.7 24' 0" to 27' 7" 7.3 to 8.4

200 5.1 160 4.1 26' 8" to 30' 8" 8.1 to 9.3

240 6.1 192 4.9 32' 0" to 33' 0" 9.8 to 10.0

Calculating projection distances

distance from lens to screen = A × width of screen

minimum and maximum distance from screen = B

width of screen = 0.8 × diagonal of screen (for 3:4 screen)

projector lens below bottom of screen = C × width of screen (for 4:3 screen)

A = 2.0 to 2.3

B = 1.5 to 10 m (5 to 33 ft)

C = 0.11 to 0.50

1 2 ... 9 10 11 12 13 14 15 16 17 18 19 ... 63 64
