Screen Size and Projection Distances
The distance between the projector and the screen determines the
basic size of the projected image, as shown below. Because other
adjustments—such as those made with the zoom ring,
Aspect button,
and
Keystone button—also affect the size of the image, the numbers
in the table should be considered for general guidelines, not exact
measurements.
