Short Throw Projectors
Create Large Images in Tight Spaces
Short throw and ultra short throw projectors allow users to create big pictures in tight spaces, without concerns about shadows obstructing the image or light shining in the presenter's face.
These projectors have very short
throw ratios, the distance from projector to screen compared to the screen size.
For example, a "regular" projector with a 1.5:1 throw ratio would have to be 7.5 feet back to project a 60-inch wide image.
A short throw projector with a throw ratio of 0.6:1 can project the same image when placed less than three feet away from the screen.
An ultra short throw projector with a 0.37:1 throw ratio can project the same image from just 1.85 feet away.

Short and ultra short throw projectors are commonly used in:
  • Small conference rooms
  • Classrooms
  • Trade show booths
  • Small home theaters
QuickTip: Projectors with quieter fans are desirable when using a projector in a smaller space.
Short throw and ultra short throw projectors are popular in classrooms and education settings. But they can also be used in businesses, sports bars and home theaters.
Short and Ultra Short Throw Projector Pros and Cons
These projectors' biggest asset is that they can be placed just a few feet or inches away from the screen. People who thought their home theaters were too small for a projector can now get larger-than-life movies and sports in their living rooms.
Our education customers say they no longer have to worry about students putting their
grubby little paws er, hands on the classroom AV equipment.
Short throw projectors also prevent shadows from obstructing the projected image. And no more concerns about light shining in the presenter's face.
But short and ultra short throw projectors have limited placement flexibility. Most have
fixed lens and no zoom. They also usually have a fixed offset, the distance the top of the projector has to be in comparison to the bottom of the screen. You have to be very precise when installing these projectors.
