What would be ideal room size?

[erpauls]

I am wanting to build a 7.2.4 dedicated Home Theater with 2 rows of 3-4 seats. Back row elevated. Wanting a screen size of approx 150-165".
I want the back surround to be behind the back row. Wanting isle room on each side. Speakers will be in-wall with the fronts all behind screen. Atmos will be in ceiling.
I want the front row to have a bit of Wow factor when viewing.
I was thinking 14'ish by 20'ish but now I am 2nd guessing the size.
I am building the room in the basement.

For me, the ideal room is ANY room my mother-in-law is not in. How deep is that basement? I mean, Atmos speakers and elevated rows and all.

Is this a custom built room, you are thinking of? What are the limitations (how high can a drop tile ceiling or whatever you plan be? Other wall dimensions?

Main thing I would stress is that you want to avoid measurements that are multiples of another (sorry, Maz) and square rooms. If you really wanted to do it to the nines you would look for Golden Ratio measurements.

When it comes to planning seating and distance from a screen that size, I can't advise... not my cup'o'tea. I have a room with one seat!

You mounted a TV across from the toilet, didn't you?

When I was building my house, I saw an online article from the Audio Engineering Society. They have some room ratios of H:W:L.

One of the ratios is 1H: 1.57W: 1.87L.

Since I wanted my ceiling height to be 14FT, the ratio came out to be 14H: 22W: 26L.

I think another ratio is 1H:1.4W:1.9L.

Another one with longer L is 1H:1.5W:2.5L

So if the Ceiling H is 10FT, then
1) W = 14FT, L = 19FT
2) W = 16FT, L = 19FT
3) W = 15FT, L = 25FT

But there are other ratios as well.

My room is 14'x20' and it's not large enough. I wish it were 17'x24'. I feel the size I have currently is the absolute minimum for a quality experience but don't expect much shoulder room if you want more than a few people in there with genuine theater seats

.

Here's a video of what the room looks like just before I installed the 158" cinemawide screen shown below.

I was thinking it might be an hypersonic anti missiles.

More likely ultrasonic?
