I think I would swap the smaller sofa and put it n the tv room and put the larger one centered, floating in front of the fireplace. I'm not usually a fan, but since your window is off center, I'd try putting the small sofa at and angle, right of the window and face it to a tv in the opposite corner. For the bay window in the formal space, I think it would be a great spot to put your barrel chairs with a 36" round table height side table. What a wonderful place to have morning coffee, read a magazine, play a game of chess, etc or even maybe do a small puzzle. Like this arrangement, but a small round, game size type table.

You size the chandelier to the size of the table, not the room. After you decide on your table, choose a light that is about 1/2 the size of the table. Hang a chandelier "approximately 30 to 34 inchesover a table with an 8 foot ceiling height. If your ceiling is higher than 8 feet, mount the chandelier an additional 3 inches higher for each foot of ceiling." In other rooms, you chose size by adding length and width of the room (feet) and converting to inches.

I think these are my favorite! i never would have pushed the furniture over that far towards the stairs. But I like it. what would you put in the back "nook" and then now at the bottom right of the layout (which leads into the dining room)? anything? Kids toy organization will go somewhere for the next few years :)

Like Julie Anne, I would use a round table with 4 chairs over by the sliding door. If it expands to oval shaped with 6 chairs, even better! However, I wouldn't do a second table under the chandelier. Instead I would have that chandie replaced with a flush mount fixture and add a chandelier over the dining table. Then I would put a sofa facing the fireplace. The tv can go in the nook to the right if your tv is small enough, or over the fireplace if it is larger. In either scenario I like the idea of shelves in that nook. Put a pair of chairs in front of each window. The ones to the left of the fireplace can share a round table between them. I wouldn't use bar stools, personally. They are hard to slide in and out on carpet and they will restrict your furniture placing options. Instead I would tuck a bookshelf into that spot (because I always need more book storage!) Or just ignore it entirely; when you have guests they will enjoy leaning in the counter just as much as they will enjoy sitting on stools, if not more.
