Is the size of your dining area suggesting a particular SHAPE?
The shape of your table is influenced by the size of your dining room. For example, a 36-44 inch square four-seater dining table or a round dining table with a diameter of 36-48 inches will keep a small space from looking cramped.

For instance, a 72-inch long rectangular table can comfortably seat six people if there is enough space for traffic flow, while a 96-inch long rectangular dining table design can comfortably seat eight people.
