Q
Calculation formulas for projection distance
Any other projection distance can be obtained according to the screen dimensions (m) using the following
calculations. The calculation result is with the "m" unit. (The calculated distance below may contain a certain
error.) If the screen dimensions are written as "SD",
For 4:3 aspect ratio
For 16:9 aspect ratio
Screen height (SH)
= SD × 0.6
= SD × 0.490
Screen width (SW)
= SD × 0.8
= SD × 0.872
Min. projection distance (LW)
= 1.560 × SD
= 1.700 × SD
Max. projection distance (LT)
= 1.720 × SD
= 1.874 × SD
Note
z
The throw ratio is 1.95 to 2.15:1 when the projection size is 2.54m (100").
