            60
When projecting from the ceiling, align the lens as closely as possible 
with the top of your screen:
Calculating Image Size and Projection Distance
The distance between the projector and the screen determines the 
actual image size. To determine the exact distance required for a 
particular image size (or to determine the size of an image at a 
particular distance), use the formulas given below. (Remember that the 
size of the image can be changed by rotating the zoom ring; see 
page 63 for more information.)
