What distance should a rear projector be?
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 far back does a projector need to be for a 100 inch screen?
8 ft.
For example, the specification “100-inch @ 8ft” means that the minimum distance you will need is 8 ft. from the projector to the wall to get a 100″ screen.

What is the best distance 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 far back is 110 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.

How do you calculate projection size without changing distance?
If your projector has a zoom lens, the lens can be adjusted to change the size of the screen image without changing the distance of the projector. Since each projector lens is different, an online projection calculator tool will help you calculate the size of an image on a screen relative to how far the projector is placed from screen.
How do you find the distance from the screen to projector?
So, beginning from this formula, we can derive the two formulas for calculating the distance from the screen and the width of the screen, respectively: D = Rt * W. W = W/Rt. Now, for our purpose, we need to calculate the distance from the projector’s lens to the screen.
What are the different throw distances for projectors?
A few common throw distances are: Long Throw: Providing very large images, this type of throw is usually from projectors that are installed in the center of the ceiling in a large room.
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.
