Screen Image Size Vs. Distance – ViewSonic PJD5134 Projector

Screen Image Size vs Distance

ViewSonic PJD5134

A while back we wrote a review of the ViewSonic PJD5134 projector. We tried to cover the most important aspects. However, did receive a specific question concerning, “screen image size vs. distance”.

  • What’s the maximum image size?
  • How far does the projector need to sit back from the screen?

The minimum and maximum image display for this model: 24 – 300 inch diagonal.

Of course realize, to produce these different screen sizes 24 and 300 inches and all in between means the projector will need to sit back at various distances from the screen.

Not to insult any one’s intelligence but the larger the image the further back the projector will need to sit. So in order to produce the 300 inch diagonal will require the furthest distance and the 24 inch will sit the closest.

Calculating the distance

There was once a calculator at the ViewSonic website which allowed easy and fast calculation of the distance for the ViewSonic PDJ5134 but for whatever reason they have done away with this.

However, the throw-ratio can be used to calculate any distance vs screen size.

The throw ratio of the ViewSonic PDJ5134 equals 2.04:1.

This means for every (1) foot this projector sits back from the wall the screen image produced will be 2.04 feet wide or approximately 24 inches.

  • 2 feet – 48 inches
  • 3 feet 72 inches
  • 4 feet 96 inches
  • 5 feet 120 inches

In order to produce the 300 inch screen image the ViewSonic PDJ5134 will need to sit approximately 12.5 feet away from the screen.

Keep in mind when setting up

One of the most common reasons for buying a projector is the person wants to view a big screen, whether it be for movies, gaming or presentations.

But keep in mind just because a projector is capable of producing a 300 inch diagonal screen image this doesn’t mean the image quality will look the best at this size.

We suggest you test different distances and lighting environments.

At certain levels of light the image may look best when the screen image is 275 inches or 250 inches rather than the maximum of 300 inches.

What if I place this projector at 20′? Can I still acheive a 150″ screen with decent quality?

Hello Patrick, at 20 feet, you will be able to produce a 150 inch diagonal screen image with decent quality for this projector but at this size it should be used in very low ambient light conditions. This is a quality projector for the price. Take care.
