Consider Shape. You have several shapes from which to choose. The two most common shapes are rectangular and circular. Some people prefer a circle shape believing that this shape facilitates better conversation. It's easier to fit more people around the table with a rectangular shape. If you add leaves to a circular table it will become an oval. An octagonal table is another option.
Thinking about where you place the furniture in the room is an additional tip for decorating a small dining room. Even your dining room might add to your well being when designed with Feng Shui in mind. Easy access into a room will make it seem more spacious so place your furniture away from the doors. If you can steer the eye from the open door to a bigger piece like a server or mirror can help divert the eye and give the illusion of space.
The place where everybody in the house gathers for good food and conversation is the dining area. Everyone convenes and enjoys pleasantries exchanged over food and beverage. The function of the room is of course obviously in line with the functions of the furniture in it. As the dining room is used for eating its flagship furniture that garners the most attention and usage is the dining room table. Other dining room furniture work in coordination with the dining room table and together they create the functionality and good atmosphere of the dining room.
