Hi,

I have building my home theatre for what feels like forever now, and am nearing the finish line, but I still am going back and forth on my aspect ratio. I am looking at buying a 150" Elunevision Nanoedge Audioweave screen in either 16:9 or 2:35.

Room Height: 6ft 10 inches
Room Width: 15 feet
Room Lenght: 20 feet
Projector: JVC 570/590


Is there any easy way to calculate the aspect ratios for each screen? What I mean by that is, how big will a 2:35 movie be on a 16:9 150 inch screen, and how big will 16:9 media be on a 2:35 150 inch screen. Note: I suck at math ;)

It's a hard call for me as I watch a lot of movies with the family, but also a lot of sports/video games in personal time. Any advice would be appreciated.

If you go to this page for the projector you are looking at you can put in sizes in the calculator and AR’s and it will show you all the screen sizes. It will do the math.

The big question is what method of presentation will you use CIH, CIW, CIA, or CIH+IMAX.

Constant image height would be the scope screen. Constant image width would be the 16:9 screen. Constant image area would be a larger 16:9 screen where you don’t use all the area all the time. Then there is what I like CIH+Imax. It will allow you to watch movies like Dunkirk where the director switches between scope and IMAX 1.89:1framing. Of course you can watch all movies on any of the screens it will just be your level of immersion wont be as desired or intended by the film industry.

That’s about movies and watching sports you should watch them as large as you like. Lots of sports have graphics around the outside of the image and I find the action in the middle is great at IMAX size.

Once you decide on the presentation method you like then you have to decide on seating distance.

Try this calculator out. You can compare the two sizes over each other to give you an idea what will fit and it will give you the the size what ratio will fit inside of which one you go with. Just to let you know that the 150" 16:9 is 6'-1.5" tall vs the 150' 2.35:1 at 4'-9.75". With you your room being 15' wide you could go with a 163" 2.35:1 screen. The width is 150" wide and the height is 63.84". That is the size I am looking at.

The other thing to look at is how far are your eyes going to be from the screen. This screen distance calculator should help as well. You usually can have a wider screen with scope and fit a good size 16:9 screen inside of it. Now to enjoy the scope screen you will need a projector that can zoom out to that ratio. Your JVC should do that no problem and with lens memory it is all at a push of a button.

Thanks for the links. The first link is exactly what I was looking for. Thank you!

I wish I could do that 163" properly im not confident it would work. While the room is 15 feet wide, there is a HVAC line that runs along part of the wall which could cause some issues. It would be a no brainer imo if I could fit a 163" 2:35
