Hello everyone!\n\nWhile I am waiting for the arrival of my new speaker system, I have been trying to find the best way to place them (on paper) in the space I am planing to use as a home theater and based on that, make a decision on the projector screen size.\n\nYou can see below the two orientations I ended up with:\n\n\n\nThis is the living room of the house which is about 4x4 meters (or 13x13 feet).\n\nI will either start with a 5.1 Atmos system or, depending on my leftover budget, go for a 5.1.4 Atmos system. In both these layouts I included the on-ceiling speakers anyway (circles marked with the Letter L) to make sure there are no issues.\n\nWhen it comes to speaker placement, I used the the Dolby guidelines and found that for the ideal layout I will have to seat either 2.75 meters or 9 feet away from the projector screen (Marked as PS in my drawings) on the left layout or 3 meters or 9.8 feet on the right layout.\n\nOn the left layout, I can use a fixed screen on the wall which can be either 100" inches or up to 110" but in this case the L\/R Speakers will block the lower L\/R Sides of the screen.\n\nOn the right layout, There is a massive window and a balcony door so I can only use a pull-down screen but on the bright side there is enough space for an 120" screen. There is also a stone wall behind the seat on the right layout which might affect the sound in a good way.\n\nThe speaker size will be W23xD35xH55cm for the L\/R (same size for the center one placed horizontally) and W23xD30xH35 for the surround speakers. As you can see in my drawings, only the center channel on the left layout is the right size but imagine that the rest of the speakers will take about the same space.\n\nFor the projector I will either go with the new triple laser HDR10+ samsung projector if it's reasonably priced with good reviews, the new Optoma P2 or the LG HU810P but I would like to avoid a long throw projector. In any case they will be enough whether I decide to go with an 100" or a 120" screen.\n\nWhen I watch a movie I want the screen to cover my field of view so, based on your experience, will the 100" screen on the left layout be enough from a 2.75m\/9 feet distance or should I push to 110" and place the speakers in front of the screen.\n\nI would really like to hear your opinions on the layouts I drew to help me decide on both the speaker placement and screen size. I would also welcome any corrections or recommendations since I am new to this and all my research so far is purely theoretical, not based on previous experiences.
