How far away should I place my AtmosKIT Plus projector?

The AtmosKIT Plus includes a ViewSonic projector with the following throw specifications:

  • Throw Ratio: 1.2:1 (1.2 feet from screen creates an image 1 foot wide)
  • Range of distance: 28.8 inches (closest) to 120 inches (farthest)
  • Projection Size Width: 24 inches (smallest) to 100 inches wide (largest)

Using the Throw Ratio information, it’s easy to calculate how large your projection size will be depending on the placement of your projector. For example, here is a table which shows how wide your projected image will be based on the distance between your projector and the projection surface.
