The bottom of the image can move from half way below the pro-

jector’s lens (Figure 5) to parallel with the lens (Figure 6).

Example:

With a 10’ image, at the lowest projection angle, the bot-

tom of the image is 5’ below the projector’s lens; at the highest

projection angle, the bottom of the image is parallel with the lens.

Once you know the diagonal image size, you can figure out the

width and height using these formulas:

width (inches) = diagonal (inches) x 0.8

height (inches) = width (inches) x 0.75
