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—vp6320 series
Image size (diagonal) Image size (width) Distance (lens to screen)
(inches) (meters) (inches) (meters) (inches) (meters)
30 0.8 24 0.6 43 to 50 1.1 to 1.3
40 1.0 32 0.8 58 to 67 1.5 to 1.7
60 1.5 48 1.2 87 to 101 2.2 to 2.6
80 2.0 64 1.6 116 to 134 2.9 to 3.4
100 2.5 80 2.0 145 to 168 3.7 to 4.3
120 3.0 96 2.4 174 to 202 4.4 to 5.1
150 3.8 120 3.0 217 to 252 5.5 to 6.4
180 4.6 144 3.7 261 to 302 6.6 to 7.7
200 5.1 160 4.1 290 to 336 7.4 to 8.5
240 6.1 192 4.9 348 to 400 8.8 to 10.0
270 6.9 216 5.5 391 to 400 9.9 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 = 1.7 to 2.0
B = 1 to 10 m (3 to 33 ft)
C = 0.11 to 0.41
vp6320 series
A = 1.8 to 2.1
B = 1 to 10 m (3 to 33 ft)
C = 0.11 to 0.43
