Move furniture to one side or out of the room.
Measure the width and length of the dining room and determine the room's center.
Push the table to the center of the room, so that the table's central point is over the room's center point, and push the chairs into place around the table. According to Tips for Effective Dining Room Design, "Arrange furniture in circular, square or octagonal groupings in the middle of the floor. Position dining chairs so they back in the direction of a wall rather than a doorway. Neither the dining table nor any of the chairs should be positioned under a false beam."
Arrange buffets and china cupboards around the room in complementary positions to the table. Take care that no chairs back into glass-fronted cabinets. Tall cupboards should be placed against walls and not in front of windows.
