150" CinemaScope too big for my view

Not in my opinion I have a 133" scope screen (with lens) with around the same seating distances - first row @ ~11' and second row ~15-16'. If I did it over again, I'd go bigger, probably close to 150". If you go that size, just consider if your PJ can get enough brightness for your tastes...

I also have similar seating distances (~10' and 15.5') and a 136" scope (108" 16x9) screen.

I would NOT go any bigger, as the front row is about as big as you can get without having to move your head around. I was very concerned about the size being too big during construction. Going smaller didn't really change the "feel" from the front row, but did make a negative impact from the 2nd (which is my primary row).

So now you have both opinions.

My recommendation is that if at all possible, test the screen size before deciding - use a sheet or photographer backdrop paper to see how it feels to you. After, of course, sizing the projector, etc. I did that, knowing the PJ would be able to handle the screen sizes I expected - and didn't order the screen until I had the room done with the PJ on-hand to validate the setup.

is there a formula about the maximum 21:9 screen size and the seat distance?

Thanks

Use the normal forumulas / guidelines based on your 16:9 screen size, since you'll be using that aspect as well - and, well, by definition here, the screen height remains the same for 2.35 content...

I agree. Get the projector set up first.

except a lot of those specify sizes based on 16:9 screen widths, not screen heights so if you go with those you'll end up with a rather small screen.

I'd contend that if you get the 16x9 screen size correct, you have your screen height, and therefore the correct 2.35 size... Now, whether that fits between your walls, well, another issue...

Yup, agree, it just wasn't clear that's what you meant

2X-3X screen height will take full advantage of a 1080+A lens projection system and 2.66X-4X SH will give you the comparable pixel density if using the Zoom method with its 800 lines.

I found this


As I'm having the same problem regarding screen size and viewing distance in 2.35:1 and 16:9, my idea was to optimize the room for 2.35:1 material.
Since thats the main AR I watch and I prioritize. So I will sit in the second (middle) row.

For 16:9 I will sit in the front row, which should give me a more immersive feeling as I'm used to.

My screen is 120" 16:9 now, so I will size that a little up to 137", which give me around 170" in 2.35:1 with the lens.

Agreed. If zooming, you will need to work off the image height of the zoomed 16:9 image, not the screen height. Therefore you will have to sit back a bit further than you would if using an A-Lens. Still enjoyable though.

That's a big screen, make sure your projector will work at the throw distance you have and be bright enough to be acceptable...

Also, what are you seating distances? Highly recommend you test the size out before committing. I'm about 10' at my front row to a 108" (in 1.85) screen, wouldn't go any bigger than that.
