How should I match the aspect ratio of my projector and screen?

with No Comments

It is important for the Projector and screen to have a matching aspect ratio. Aspect ratio is essentially the screen’s size. It is called a ratio because for each measurement of screen width, there is a corresponding measurement of height.  For example, a 16:9 aspect ratio means that for every 16 units of measure in width, there will always be 9 equal units of measure in height. This discussion illustrates the importance of always pairing a projector and screen with matching aspect ratios.

  • [22:04] Josh: I need a fixed frame screen 100×160 (16:10 format)
  • [22:04]        Rick: I would be glad to help. Are you using a native format 16:10 projector?
  • [22:05] Josh: Just trying to find what screen model would be recommended for this .
  • [22:07]        Rick: Using your  specs (160:100” as a 16:10 aspect ratio) calculates to a 188.67” sized screen. The formula for calculating screen sizes is here:   The largest size  we currently make in 16:10 is 144″ (diagonal).  The model would be our ezFrame R144WX2 with viewing dimension as 76.3″x122.1″
  • [22:08] Josh: Is there a reason why they are not made larger?
  • [22:08]        Rick: Currently, our buyers have not shown much need for sizes larger than 135” so we currently don’t make 16:10 screens larger than what our customers are asking us to make.
  • [22:08]        Rick: If you are able to use 16:9, we can go much larger. We don’t have 188.67” sized screens but we can do well over 200” if you would like.
  • [22:08] Josh: The projector is 16:10 native. If we go with a 16:9 screen, would that work?
  • [22:09]        Rick: The projector may be switched to 16:9 mode and it will fit but the quality will not be as precise in its picture quality as a native 16:9 projector will be.
  • [22:11] Josh: Okay, do you have a way of determining  1- How big my screen should be? 2- How big an image my projector will create based on its
  • [22:12]        Rick: Our Screen calculator will tell you all about the throw distance of your projector ( by make/model)   We also have a tech tip on proper projector throw distance:
  • [22:12]        Rick: I also recommend this video on proper screen size based on viewing distance:  here is also a video on aspect ratios to help settle the difference between whether a 16:9 or 16:10 would serve you best
  • [22:15] Josh: Perfect.  Thank you for your help.
  • [22:15]        Rick: My pleasure. Thank you for choosing Elite Screens.
