2.35 is somewhat of a misnomer, it's actually 2.39 for most movies.

Screen dimensions for 2.35:1 CIH setup
This might sound a little silly, but I'm about to order a screen and want to avoid making a mistake.
I had decided on a 132"x56" 2.35:1 screen, which is 100x56 for 16x9.
However, when I zoom for 2.35 material, the 132" width is filled before the height (56") is. If I fill the height, the wide goes over by about 2". I've tried several movies at this point and they're all pretty consistent in this respect.
So, I'm puzzled. 56 x 2.35 = 1.31.6, not 134.
Can someone enlighten me?
Thx.

So what do most people do - order a 2.39 screen or rely on projecting part of the movie onto a light-absorbent frame?
One way around this is to use a Prismasonic lens. You can adjust the stretch to precisely fit the sides of your screen.

What's the ballpark cost of one of those?
I have a 2.35:1 screen and most movies that are labeled 2.35 fit the screen perfectly. However, 2.39:1 and 2.4:1 movies need to overshoot on the sides to fit on the screen. I was shocked the other day when I wanted a 2.35 movie to test something, and the first 10 or so I grabbed were 2.4:1. No matter what shape screen you get, some films will not fit just right. I'd probably still stick with 2.35 (vs 2.4) if I had to do it over again.
Ian,
Will you end up using a lens or remain with the zoom method? If you use a lens, the lenses are based on 33%, so 1.78 x 1.33 = 2.3674 or 2.37:1 (rounded)...

I was going to start with the zoom method, and then maybe switch over to a lens. Sounds like the very least I should do is go with 2.37:1, which puts me at 133" wide (based on 100" wide 1.78:1 screen).
I'm using YXY on my HTPC to do the stretch, so I've just adjusted it to fit my screen.

One thing that can get confusing as you discuss screens is that normally 16:9 screens are referred to in the diagonal measurement but anamorphic screens 2.35:1 or similiar are usually referred to, at least around here, by the actual width of the screen, for instance my screen is 51"h X 120" wide.
So are you saying your screen will be 133" wide? if so does your projector zoom that large an image from where your placement is?

Yes, 133" wide. I'm using an RS1 and I have it back so that it's near max throw for 16:9 (100x56) and it zooms easily to 133" wide.
I suggest wide velvet screen borders to allow some flexibility in setup.
Anyone think brightness will be an issue with 133" wide 2.35 HP screen using zoom method (where proj is at max throw for a 16:9 image)?
