Well I have been lurking around this forum for a while now. I have my theater framed out with drywall in and am thinking about going CIH. My first row of seating is about at 9 to 9.5 feet with an AT screen (due to room length constraints). Here are my questions:


1. Is 9 foot seating too close for a 10 foot wide AT screen? I am looking at shearweave 4500 (DIY) and concerned about seeing the holes and possibly sitting to close in the first row. If I bag the AT screen I am down to about an 8 foot wide screen (due to room width constraints) which seems kind of small to me for a 2.35 setup when the picture needs to shrink down to 16:9 for certain movies and TV.


2. I am working with the calulator on projection central. It does not have a 2.35 calculator. Can I use the what the 16:9 image would be on my 10 foot screen to get the correct lumen rating? The 16:9 image would be about 90.78" wide on the 10foot wide 2.35 screen. If I use the zoom method initially, will my lumens then decrease from what I computed using the 16:9 image as my guideline.


Hope this makes sense. Thanks all.

Seating distance ,although there are standards, is a personal thing. I've always sat in the front third of a commercial theater. If you like that kind of thing themn at least for field of view that won't be too close. The visibility of texture for SMX is about 8' for me so you are right around that and, depending on your vision, fL , etc you could see the weave.

In my theater I have an SMX screen 120" wide 2.35 screen and my seating is 9.5 and 12.5 and you can't really see the weave from either one. that being said 4500 is not exactly the same and I think you would see it.

I suggest if you don't have the material yet that you check out the Seymour screens DIY fabric, which is closer to SMX but still available to DIY.


some things you don't say and that might make a big difference it what are the actual dimensions of your room? What would the projector lens to screen surface distance be?


and is it that you only have 8' wide total to put up a screen or that you want room for side curtains or what? I assume you are putting R, L and Center behind the 2.35 screen.

If you answer these questions you can get better answers.

I sit 9.5 feet away and my 2:35 screen is 84" wide. 120" is WAAAYYYY too big from that distance. MAYBE 8 feet if you're really into immersion and you don't mind watching movies like you would a tennis match. I personally find 7 feet wide to be the perfect 2:35 width from 9.5 feet and if I had it to do over again would do exactly the same thing.

Thanks all for your replies.


I have not selected my projector / lens setup yet. My exact room dimensions are 17 x 11.5 without the screen wall in. The primary reason why I was looking at AT was to get a bigger screen with the secondary benefit of putting all three speakers behind the screen. I can fit an 8 foot non-AT screen but then my width is cut considerably by going with CIH.

What about a 10ft non-AT screen with the front 3 speakers right below the screen?(horizontal) It might be a decent compromise and would make the room longer for more seating flexibility.
