Depends if you want to "wall off" access to the living room, and what view you want most of the time, does it not?

You want only a sectional and tv? No chairs ? No cocktail table? ..................I'm snoring, actually.

A room is more than a couch and tv, if it's inviting.

For clarification:

There are no windows in this room.

You have a sectional but plan to replace it with a larger sectional, so you are not keeping the existing sectional.

Placing the TV on the larger wall makes more sense to you, but I'm not there yet, so can you please help me understand why it makes more sense? Is it so you can see it from the dining room and kitchen?

Placing the TV on the larger wall and/or? having a larger couch will allow better TV watching? Which will? The larger wall or the larger couch? How many people watch TV together in here? Are all your friends coming over for the big game? Do you and your spouse and kids (how many?) love movie night?

If you place a sofa as a divider between the dining room and living room, yes it will block off the space, but if the sofa is low, it might not be a bad thing. Does the room feel too spacious to be comfortable? Also, I can say with experience that anyone sitting on the sofa will block or at least distract the view for anyone sitting in the dining room. And people on the sofa will feel conscious of being easily observed.

What other furniture is in this room. Jan asked about tables. Will any existing furniture stay? Or can it be considered a clean slate?

That odd corner….. What do you think it was intended for? Do you think the plan was to have a TV there? So that furniture could be placed opposite IT? Like a sectional channeling traffic to the dining room like you suggest?

So the TV is wall mounted. Is there no furniture under it making it at least visually supported and to store the router/modem, speakers, and media? Is it just suspended in space on the wall? Is it a dark wall to help it blend in? Or is it a white or light wall?

The width of a 65" tv is 56.7", so it also would fit on that smaller weird corner wall. The wall could be painted in a darker color to provide less contrast between it and the black TV. Or you could visually ground the TV with a media storage cabinet below it.

Then you could either leave the sectional where it is or rotate it clockwise either one or two turns. Or you could replace it with a sofa, two chairs between this room and the dining room, some side tables, and a coffee table or ottoman. 

Your turn...

Hi. Advantages to proposed change is that you no longer have people walking between the tv and the sofa. Disadvantages are what you stated above. So, your choice.

Secondly, I don't know that you necessarily will be able to buy a larger sectional, with the proposed arrangement. Note that you will need at least 3 feet (recommend 4 feet) between the back of sectional and the dining room and on the sides of the sectional (including any end tables

Take the sectional and turn it in the proposed direction and see how you feel about it.

What are the dimensions of current sectional?

IMO sectionals are rarely good choices for seating and in awkward spaces really poor choice . Post some pics of the space to start. Where are the windows and what size are they. How many seats do you actually need and is this the only space you have for a TV.

Thank you for the comments, it is very helpful! KL- the odd corner is a fireplace which is too high to place a tv above it. Yes, one goal would being able to see the tv from the dining room and kitchen while cooking. I watch sports and when the tv is on the largest wall, I feel it will be easier to concentrate without other distractions (more cozy and will block the room off- not seeing the kitchen and dining room on the left side). CDR design- the sectional is 120 " x 81 ', currently with the 81 inches facing the tv on the wall. That is a great point that I need three feet on each side for clearance! I agree that sectionals are not a good choice for this room, I would like to buy a new sofa and loveseat set. Currently I also have a lazy boy recliner (parked in front of the tv ) and three ikea lack side tables (each 22x22 inches). The recliner may have to go to give more space. The tv is wall mounted with cables running in the wall, Next time around, I will just buy a tv stand so that the set up is not so permanent and I can change it up easier!

Thanks. Really tight with the sectional turned. Only 30" on each side and on the dining room side and 23" near the fireplace. (less on angled area). That is with zero end tables.

If you want the tv on the long wall, get different furniture. Do a detailed floor plan with the items you want and generous walkways.

Does this help you think clearer about a good view of the TV?

Haha! A fireplace...of course!

Can I suggest a loveseat and two chairs if, after all the measurements, you still feel cramped with a sofa and loveseat... Which is basically a sectional.

I've been thinking about your room. I wondered if you center your TV on the big wall like you want, so you can view it from the kitchen and dining room...not on the wall itself but lined up with the kitchen and dining room... Then get a love seat to put directly in front of it, can you flank it with two swivel club chairs? For drink/snack tables, can you put a really small table by each club chair? Would there be room for a narrow console table behind the loveseat? Might there be room under the console for a pair of stools? I can tell TV watching is an important thing you enjoy. I still don't know if you have lots watching with you or just you or maybe one other. If lots, the club chairs and stools might be handy.

That leaves you with what to do with the space on the other half of the room and what to do with the wall where the TV used to be. I guess you have to think about what else you want to be able to do in there, and what you need room for. Might they house storage, displays, art?  Do you need mirrors, accent lighting?

Thanks! Like cdr above mentioned - i tried out the new set up by moving the room around and it makes the space more cohesive and functional. i think you have a good idea to place the console table behind the sofa to define the space. Beyond just changing the space for the tv set up, it makes sitting in this area nicer as it is its own defined space. in the future when prices are better I will consider a 72- 75” sofa with swivel chairs.

Oh, cool! I didn't read that you had tried moving the furniture already. Sorry…must have missed it somewhere. And there's room for a full sofa instead of a loveseat? I personally switched from sofas to loveseats because nobody ever sat in the middle…wasted realestate…and I think it looks fine.

I have to say, we also have a line-up like you. Tv on the back wall of a long narrow family room. We have half a sectional underneath it for sitting and staring out the sliders with the TV off. The other half of the sectional facing it across a big square coffee table is perfect for watching tv and enjoying the fireplace next to it. Behind the sectional is a kitchen table and a Nordic Track. Behind that and two steps up is the kitchen with a bistro table. We watch TV while cooking, eating or crafting at the table, using the Nordi and just sitting. It's a very agreeable setup.

I would think twice about placing a console table behind the sofa. How close do you like to sit to the tv? In the floorplan you drew, with the sectional 7 feet from the tv, you had only 30" behind the sectional.

Sofa spaces do not need to be defined. They are large enough to define themselves.

Bottom line, make sure you create a floor plan down to the inch, so you know what size sofa to buy and what size swivel chairs. Allow for any end tables.
