How do you calculate projected distance?
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.
What is minimum projection distance?
Short throw projectors need to be between 5 and 10 feet away from the screen, depending on how large of an image you want.
What is the projection distance?
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.
How far should a projector be from a 120-inch screen?

How much space is needed for a projector?
The absolute “best” distance between the projector screen and room seating is hard to calculate. Instead, a general rule is that seats should be located a distance that is no less than double the width of the projected image, and no more than five times the width of the image (the furthest seat from the screen.)
How wide is a 120 inch projector screen?
How far should you sit from a 100-inch projector screen?

How far away should you sit from a projector screen?
So, if the width of your TV is 55 inches, the minimum viewing distance should be 110 inches or around 9 feet, while the maximum distance should be 275 inches or no more than 23 feet. In short, the first row of recliners should be placed at least 9 feet away from the screen.
