What is Zoom in Projectors?

In simple words, the Zoom feature in Projectors allows you to make the Image smaller or larger without moving the Projector closer or farther.

First, you should know How Projector Throw works. When we want a larger image, we move the Projector close to the Projector Screen. Similarly, when we move the Projector far from the Projector Screen, we get a bigger picture. 

However, there is a limit to increasing or decreasing the screen size. It depends on the Type of Projector. 

So, with the Zoom feature, you can adjust the screen size without moving the Projector. If the video is out of alignment, then you should use the Keystone Correction. 

Zoom Ratio:

Zoom Ratio indicates how big or small you can scale the image. For Example, if your Projector has a Zoom Ratio of 1.5, you can Zoom scale the picture 0.5 times (50%) of the current screen. Suppose your projecting screen size is 10×10. You can zoom it upto 15 x 15 feet.

Some Projectors have a Zoom Ratio of 0.5. That means you can Zoom out upto 50%.

Projectors can have a Zoom Ratio between 0.4 to 2.1

Example:

Let’s take this Epson Home Cinema 5050UB 4K Projector as an example. It has a Zoom Ratio of 1.0 to 2.1. That means you can Zoom In from 1.0 to 2.1

Difference Between Throw Ratio Vs Zoom Ratio:

The Throw Ratio tells you how far you need to place the Projector from the Screen. Whereas the Zoom Ratio shows you How much you can scale the image. Both are different.
