To determine the projection distance when you know the
diagonal size of the screen image:
❏ Inches:
Maximum projection distance = (1.967 × diagonal size) – 3.224
Minimum projection distance = (1.554 × diagonal size) – 3.563
❏ Centimeters:
Maximum projection distance = (4.996 × diagonal size) – 8.1889
Minimum projection distance = (3.947 × diagonal size) – 9.0500
For example, here are the measurements for three installations:
* For an image size of 320 inches, the projector may be up to 52.1
feet away from the screen, depending on the setting of the zoom
ring.
