How do I determine the screen size and aspect ratio?

by on November 16, 2018 with No Comments

This discussion covers the process of calculating a projection screen’s width, height, and diagonal size. It also covers aspect ratios and how to calculate them as well.

 

*The discussion below is based on actual chat transcripts with the omission of any personal/confidential material to protect the customer’s privacy. An example in this case is to change the contact’s identification name/number to “Customer” or a generic name.

 

Transcripts:

  • [18:24] Customer: We have an Elite tripod screen T99UWS1. I need the dimensions please. It looks (from pictures) to be about 72″ wide
  • [18:29] Customer: Also, may I have a quick explanation of aspect ratios?
  • [18:33]        Rick Certainly, I would be glad to help.
  • [18:34]        Rick: The dimensions for your screen’s view size is 70.0″x70.0″. It is known as a 1:1 aspect ratio. This means that for every 1 measurement of width, there is 1 equal measurement of height.  Aspect ratio simply means that for a certain number of units measures of width, there will be a set number of equal units measured for height. So, if your screen has a 16:9 aspect ratio, it means that for every 16 units of measure in width, there will be 9 corresponding equal units in height.
  • [18:35]        Rick: Getting back to your T99UWS1, the screen’s  overall height 32.1 and width is 77
  • [18:36]        Rick: and fully standing fully extending. 113.6
  • [18:36] Customer: Got it. So, for a 4:3 it is 4 units wide by 3 units high. That said, I understand that my screen is 1:1 so it is squared. Do you have a calculator that shows measurements for various sizes on projection footprints and screens?
  • [18:38]        Rick: That is correct. Yes, here is a projector calculator that gives you the specs of any kind of screen measurements in associate with the projector you are using. https://elitescreens.com/front/front/cms/slug/screen-calculator
  • [18:38] Customer: Great. Thanks. Is there a mathematical way of determining screen dimensions?
  • [18:39]        Rick Yes, here is an article on mathematically calculating your screen dimensions https://elitescreens.com/front/front/newsdetail/news/207
  • [18:40] Customer: Thanks.
  • [18:41]        Rick: Also, here is a video on aspect ratios – https://elitescreens.com/elitetube/aspect_ratio_edu.mp4
  • [18:41] Customer: Okay thanks for your time.
  • [18:41]        Rick My pleasure, thank you for choosing Elite Screens
