Throw ratio or Throw distance. can be defined as the distance between the screen and the projector.

According to the throw ratio. The projector is selected as a short-throw, long-throw, our ultra-short throw projector.

On the projector description. A throw ratio may be given which defines how far from the screen you can place the projector. 

The throw ratio can be mentioned as 1.4 – 1.65 (Zoom in and Zoom out).

If you need the 2m image size. Then you have to multiply the 1.4 with the 2m. 

The answer (2.8) will be the ideal distance. You should put the projector away from the screen.

And if you want to consider. Which distance is considered short-throw or long-throw or ultra-short throw.

Because you can place the ultra-short-throw projector just a few inches away from the screen. And you can project the big image on the screen.

If you have a big room with a good height of the ceiling. The long-throw projector is great for the commercial and in the home. For both places.

Because with the long throw projector. You can project artefacts free images from 8 feet and far away from the screen. 

And both types of room sizes are not available for you. Then you can go with a short-throw projector.
