What is a throw ratio for a projector?
In video projection terminology, throw is the distance between a video projector lens and the screen on which it shines. It is given as a ratio (called throw ratio), which describes the relationship between the distance to the screen and the width of the screen (assuming the image is to fill the screen fully).

How far off center can a projector be?
Most projectors provide keystone correction of +/-30 degrees or more, which allows you to square off the image if you end up tilting the projector to aim it at the screen.
Does a projector need to be centered?
A projector does not have to be centered on the screen if the projector has the horizontal lens shift range to move the image onto the screen. Not all projectors have horizontal lens shift, which is not the same as keystone correction.
Is higher throw ratio better?
The smaller the throw ratio, the larger the image a projector will produce at a shorter throw distance.
