How do you calculate projectors?
For any given projector, the width of the image (W) relative to the throw distance (D) is know as the throw ratio D/W or distance over width. So for example, the most common projector throw ratio is 2.0. This means that for each foot of image width, the projector needs to be 2 feet away or D/W = 2/1 = 2.0.
How wide is a 120 inch projector screen?
58.8″ H x 104.6″ W

What is the best aspect ratio for a projector screen?
Aspect Ratio: Different screens will feature different aspect ratios. The most common options are typically 16:9 or 4:3, but there are others out there, as well. Make sure your screen’s aspect ratio matches your projector’s for the best possible viewing experience.
What determines the size of the image produced by a projector?
A projector’s distance from a screen and the size of the image it produces are proportional to each other based on the optics of the lens. As you increase the distance between the projector and a screen the image will also increase.
