Is 2:35:1. Same as 2:39:1
When "Cinema" format first became more common as far as being the referenced content material as shot by the Studio, it was almost always in 2.35:1, and DVD packaging stated such. As time went forward, that format slightly expanded to 2.39:1 (...or 2.40:1 - a miniscule difference) and if you look on any DVD that is listed as true Cinema, the package will state either of those figures. (...more often these days it is the latter...)
So when making / buying a screen, any DIY'er or purchaser should look to a screen that is formatted to the most common denominator.
[quote]I looked at the Carl site and a little confused on which roll of flexi white to order.
Suggestions on which one. .?
Do I order the custom roll or is there a standard roll size for 2:39:1 I should order. [QUOTE]
In going with a 135" 2.39:1 <Diagonal
> ( 120" x 50") you should order this size: 53" x 126" (2.35:1) shipped in a roll.
The Flexi-White needs to be stretched equally over the constructed frame, at least 6" past the edges, and then stapled in place using 1/4" T50 Staples
Use this diagram when stapling:
Space the positions out a bit, of course, and add more when / if necessary. Spacing between staples should be no more than 1.5"
Here is a Image of such a Frame / screen.
You will note I used additional bracing inside to make certain the narrower Frame would be perfectly straight. The Frame consisted of 1 x 3s on edge around the Perimeter, and 1 x 3s ripped lengthwise to 2.25" and placed on edge for the central braces. I used a $99.99 Kreg Pocket Jig / Pocket Screws to fasten the assembly together, so all joints were square cut....no need to Miter cut corners.
Where do I order this spray. And can I spray it on the screen lets say a week or so after I have the screen up and running. Or am I Better. Laying the screen in the garage flat and spraying it or better yet in basement which will have less dust particular. How long to dry. Maybe better off to spray while hanging on wall ?
ALWAYS spray vertically, and in place if possible.
Here are links to Spraying / Mixing Videos, some of which ...most actually...) are on different materials but essentially it's always using the same process.

When I change from 2:39:1 to 16:9 viewing what will be the screen size. I Di do a search on dimensions. do I want a 71x 151 then just shorten sides to accommodate 16:9? Although i have ten foot ceiling I think that is the max height I could do in a basement.
As can often happen with a Noob, you mistakenly grabbed a hold of the diagonal Width as being the actual inches "wide" With the SONY it would be entirely impossible for you to go with a 2.39:1 screen that would be 151" wide (151" x 63" = 164" diagonal) because that size would 1st require a 18.5' throw, and would only provide at the uttermost 11 fl of brightness on a 1.3 gain surface.
Now it would be possible to stretch you available size to this point:
133" x 55" = 144" diagonal @ 2.39:1 and still clock in a 14 fl level with 1.3 gain
You's want to then order Flexi-White in the 63" x 151" size and trim it down to 142" long before stretching to make it easier to handle while doing so. Of course at the end you'll have to trim away all the excess material left after pulling, equal to the bottom edge of the edge-wise 1x 3 frame.
but be advised that going that much bigger puts you back to a place I was trying to avoid....your having much less screen brightness to help offset ambient light. Yes....you will gain between 20" to 24" additional screen width and between 9" to 14" additional diagonal. That size (144" diagonal) increase will up the size of your 16:9 image from what a 50" to 55" high screen would be.
But foot lambert brightness will take a good size hit.
Something else to touch on that is relevant. The 350ES is native 1.9:1 not 16:9 I rethinking things, it might be best for you to get the PJ mounted first, and shine actual 2.39:1 content on the wall, as well as 16:9 content.
The 350ES has a few features working for you. Power Zoom and shift, and a type of Image Size memory that allows you to black out unused pixels. It might be well advised to do some watching and adjusting first and then build your screen based on what you observe your size parameters are. Once you have some concrete measurements, we can more effectively advise you on what sizing to use/ how to build your screen frame...and lastly, what type / style of Masking would be most effective.
Sending you a PM with a contact number should you need any real time advice during your trying to factor in your screen size adjustment.
Good luck...and get started!
