Ultra Short Throw vs Short Throw vs Long Throw Projectors: Differences, Pros & Best Uses

Choosing the right projector is not just about brightness or resolution — throw distance is one of the most important factors that determines installation flexibility, image size, and overall viewing experience.

In this guide, you’ll learn the differences between ultra short throw (UST), short throw, and long throw projectors, including their pros, cons, and best use cases.

What Is Throw Distance and Throw Ratio?

Throw distance is the space between the projector and the screen.

The key metric behind it is the throw ratio, which defines how wide the image will be at a certain distance.

Simple explanation:

Throw Ratio= Distance / Image Width

• Lower ratio = closer placement

• Higher ratio = farther placement

Ultra Short Throw Projectors (UST)
