Suggestions for Optimal HomeTheatre dimensions

[Rakesh123]

Hi all,
I am looking to build a dedicated room for my HT, Currently using in my living room.I want to get suggestions on
1.)Optimal HomeTheate dimensions to be viewed by max 8 people.
2.) Planning to build this on my terrace,Want to know if I can prefer using sheets(Metal roofing sheets) for my roof over RCC slab as my understanding is acoustic treatment should take care of this and in the context of keeping the cost low.

Need your suggestions on the above.

Yes. Metal sheets can be used. But you need to spend more for the false ceiling and sound/thermal insulation below the roof. Even after doing all these you may get vibration/rattling sound if the workmanship is not proper.

For 8 seats you need to place the chairs in two rows.

For real cinematic experience you need a projector and separate pre/power amp (No AVR)

Thanks for your response.

Seems like better to be off with sheets and prefer RCC for roof.
What would be the ideal dimensions of the HT room planned for 8 people?

This is one good project with similar concept... well documented and executed.

Building a Home Theater & Listening Room

My wife finally parted with a portion of her terrace garden and let me build a home theater. First off all I find myself very fortunate to build a room that can be dedicated to music listening and watching movies. The room will be 3.96 meters wide, 7.38 meters long and a height of 2.7 meters...

3 feet space on either side of seats = 6 feet
2.5 feet per recliner ( common handle) x 4 seats = 10 feet.
16 feet wide- minimum

What should be the length of the room? Height I assume 10 feet is ok, Did you consider acoustic treatment in the width you recommended.

For a 120" screen the viewing distance should be around 16-18 feet. Since you are going to arrange two rows of seats, 20-25 should be the ideal length of the room. 16' width is good enough to accommodate acoustic panels

That's 30 ° angle of view. (120" screen from 16 feet distance)
Way too low..

Yes.. considered rightly done acoustics.
Length I would suggest around 23 feet.

Check out this wonderful home theater thread in AVSforum. The dimensions are very similar to the ones suggested. The only difference is its a 7 seater (to enable easy access to the second row). Go through it, should be very helpful to you.

What should be the ideal screen size for 16ft viewing distance,Can 150" be considered?

Use this beautiful designer tool from Audio Advice. You can get a brief idea on how to start.

180" from 16 feet gives 45 degrees angle of view.
