Q2) Is a long-throw projector better than a short-throw projector?

Well, both projectors are designed to tackle different situations and needs. What a short-throw projector can do might be impossible for a long-throw projector and vice versa.

Q3) What features should I look for in a long throw projector?

The most important feature to look for in a long-throw projector is its throw ratio. The larger the throw ratio the better. It should not be less than 15 meters. After the throw ratio, you should also consider the brightness level, resolution, and adjustment options in a long throw projector.

Well, there is no ideal count about how much should be the distance of a projector from the screen. It is very hard to calculate and come out with a value.

Q7) How can I calculate the throw ratio of a projector?

To calculate the throw ratio of the projector you first must know the throw distance. Once you figure it out then divide the distance by the width of the image and you will get the throw ratio.
