My living and dining room is 20 feet long. It is one big room. I am debating whether or not to make it a full dining room. My table will be is 6.5 feet inches long with no leaf and with an 18 inch leaf it will be 8 feet in length. My question is.... should I center the dining table in the middle of the room at 6.5 feet or 8 feet with 6 chairs. Should I purchase 2 more chairs if I insert the leaf? Or will it be alright with just six?Should I put 2 chairs on the side for a small seating area?.......The other option would be to push the dining area as much as possible to one side and split the room and then create a living room area. Please share your opinion. Is 20 feet enough for 2 rooms???
