The distance at which you place the projector from
the screen determines the approximate size of the image. The image
size increases the farther the projector is from the screen, but
can vary depending on the zoom factor, aspect ratio, and other
settings.
Note: When correcting keystone distortion, your
image is slightly smaller.
Use the tables here to determine approximately how far to place
the projector from the screen based on the size of the projected
image. (Conversion figures may have been rounded up or down.) You
can also use the Projection Distance Calculator here
(U.S.), here (Canada), or here
(Latin America).
