If you have a china cupboard that will be on one of the 12 foot walls, and it is no more than 20" deep, you can fit the table into the room, but the person at the end of the table adjacent to the family room, may need to push the chair back into the entry way between dining a family room to get up from the table. Arithmetic: 80" long table = 6' 8". Recommended chair space = 3' (36") x 2 chairs = 6' Table + chair space = 12' 8" Room length = 12' 40" wide table = 3' 4" Table + chair space = 9' 4" Room width = 11' Maximum depth for china cupboard = 1' 8" = 20"

After calculating what was written above me, it looks like you can fit the same size table I have in my dining room, which is 42" wide by 78" long with the leaf in. We can fit up to 8 people at our table with the leaf in. I also love having a rectangle table! I have two openings in my dining room - one to the living room and the other to the kitchen. I have a door on the other wall and a window on the 4th. Just place your table in the middle of the room and it will work.

Hi everyone, thank you for your input. We have lates the table out with the clearances required and we have determined that we can have a 60”x40” or 42” or smaller. We would have the following clearances. 48” from the edge of the table to the patio doors. 42” from the peninsula countertop , 36” from the back wall to the edge of the table top. These dimensions leave us with some play if needed but right now this is what we came up with. We decided we don’t want a round friable because we still want the table to extend. So now I need to find the table. I’m afraid to purchase on line due to the retune or the quality when you can’t see it. Also being in Canada all I really see is Wayfair . Please let me know if these are good . My drawing is not to scale , we have changed the 2x4 construction to 2x6 by adding a strip and new insulation so we have lost a few inches on each wall. This we did after the drawings. But my new measurements are.

That will depend on the fixtures so post pics of what ones you are considering. BTW you will need to stay with no wider than 42" make sure what you buy allows 36" min all around the table and you will pobably need a buffet too so allow for that in your measurements .We also need a bit of info as to your style. Ideally a pic of the table and chairs and space too.
