Throw Distance Throw distance is the distance measured from the front of the projector to the screen.
This is an important calculation in any projector installation as it determines whether or not
you have enough room to install your projector with a desired screen size and if your
image will be the right size for your screen.
You can quickly estimate the throw distance by taking the width of the screen and
multiplying it by the lens throw ratio; see Figure 3-2. The result of this calculation tells you
roughly how far back the projector should be positioned from the screen in order to
project a focused image large enough to fill the screen.
