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, Aspec t 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.
