Distance Between Projector And Screen
Once you have figured out the correct spot where you are going to place the screen, you can move on to calculating the distance your projector will be from the screen. For this, you will need to consider the throw ratio of your projector. The specifications of your projector will mention the maximum and minimum throw ratios. You need to multiply these numbers with the width of your screen independently to arrive at the maximum and minimum distance your projector has to be from the screen.
To provide a practical example, suppose the maximum width of your screen is going to be eight feet for 16:9 aspect ratio, and your projector’s maximum throw ratio is 2.2:1 and minimum is 1.8:1. In such a case, the maximum distance for placing your projector from the screen will be 17.6 feet (8 x 2.2), and the minimum distance will be 14.4 feet (8 x 1.8).
