Customer questions about this product

Will this projector produce a quality image sufficient for the size of my room?
To determine if a projector will produce a bright, clear, and large enough image in your space, identify its throw ratio. This ratio compares the size of your screen to the distance between the screen and the projector’s lens. This determines the required placement of the projector in relation to the screen to ensure sufficient image quality.

1.5:1 is a common throw ratio for regular projectors. This means that for every inch of screen size, the projector must be placed 1.5 in. back from the screen. To produce a typical 5 ft. or 60 in. image (measured diagonally), the projector must be placed at a distance of 7.5 ft. (90 in.) away.

If you have less space to work with, consider a different type of projector. A throw ratio between 0.38:1 and 1.4:1 is common for short throw projectors. Ultra short throw projectors have a common throw ratio of 0.37:1 or less. Let’s break it down using throw ratios in the common range for each type:

Regular Projector
60 in. [screen size] x 1.5 in. [the key number in the throw ratio] = 90 inches (7.5 ft.) [distance from screen]

Short Throw Projector
60 in. x 1.04 in. = 62.4 in (5.2 ft.)

Ultra Short Throw Projector
60 in. x 0.37 in. = 22.2 in. (1.85 ft.)
