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 de- sired 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
Estimated Throw Distance
Throw Distance (TD) = Screen Width (w) x Lens Throw Ratio
