How to identify the throw distance of projector?

How to identify the throw distance of the projector? What is Ultra Short Throw Projector? Let's see.

We can divide projectors into four categories according to different throw ratios.

Long throw Projector​

2.5:1 and larger (100 inches for images 5.5 inches and above). Most of these are conference room projectors, which are rarely used at home given the larger space required.

Standard throw Projector​

2.5:1 to 1.2:1 (100" image between 5.5" and 2.64m). Most homes will choose this type of projection, with a zoom lens.

Short throw Projector​

1.2:1 to 0.35:1 (100" image between 2.64m and 0.77m). This type of projector can be brought closer to the screen.

Ultra Short Throw Projector​

0.35:1 and smaller sizes (100" image at 0.77m and beyond). That is, almost close to the screen to project.

You can use the Projector Calculator to figure out the screen size of a certain throw distance.

Ultra short throw projectors must be paired with a special UST Screen to get the best out of both and provide the best projection.

Because the angle of the projection of the ultra-short throwl projector is about 45 degrees, and the sawtooth design of the UST screen is just suitable for the projection Angle.
