For example, here are the measurements for three installations:
| Horizontal distance from projector to screen | |
Image size (diagonal) | Minimum | Maximum |
|
|
|
300 inches* (762 cm) | 460.6 inches (11.7 m) | 586.6 inches (14.9 m) |
200 inches (508 cm) | 307.1 inches (7.8 m) | 389.8 inches (9.9 m) |
100 inches (254 cm) | 153.5 inches (3.9 m) | 192.9 inches (4.9 m) |
|
|
|
*For an image size of 300 inches, the projector may be up to 52.1 feet away from the screen, depending on the setting of the zoom ring.
Long Throw Zoom Lens Calculations (ELPLL02)To determine the maximum and minimum diagonal size of an image when you know the projection distance:
❐Inches:
Maximum diagonal size = (0.487 × projection distance) + 2.336 Minimum diagonal size = (0.286 × projection distance) + 1.458
❐Centimeters:
Maximum diagonal size = (1.2369 × projection distance) + 5.9334 Minimum diagonal size = (0.7264 × projection distance) + 3.7033
