First of all, is it possible to turn the table so that the long side is facing forward? I'm also wondering why you have a plastic cover on one of the chairs. The rug needs to be larger than what you have there now so that you can pull the chairs out and still have them on the rug. A small rug also does not look attractive. It's unfortunate that the colors of the chair lock you into a carpet color that is gray, which doesn't look very good with your brown wood floors. Is there a chance that could be changed?

My guess, from the plastic on the chair, is that you may have a child? If that’s the case, an indoor-outdoor rug may be a good idea. It doesn’t look like there is room to turn the table - I see an island that may be close by. Your rug looks a bit small. Whatever size it is, put painters tape on the floor, using the dimensions of a rug the next size up. That may help a bit.

Thank u all for giving ur suggestions. At this moment we are not planning to change the chair color. We don't have much space as someone already before so i think turning table will be more congested. We will consider the bigger size option of rug though. I have attached few more photos with both family room and kitchen so you can probably give better ideas for the rug. We are also planning to change the family room rug soon.

Also we are thinking to add curtains since few years to both the window of kitchen and family room(2 storey room) but haven't done that for the reason we are not sure what curtains will look good. Price sometime also gets into consideration due to 2 storey family room.
