What’s the shape of your dining room: While most would think a rectangular carpet should go in a rectangular room, there are often exceptions. Area rugs can take their cues from the space as well as the shape of the table that covers it. It is often a play on form and color when choosing the area rug. Decide what feels and looks right to you. Your dining room is your design preference and trends and design can be followed or broken.
Defining a space: If you have an open area dining room that shares a space with a living room or kitchen area, an area rug will help you define the dining room without using walls. Choose a rug that uses colors from adjoining spaces but still defines the space. Therefore a mixture of neutrals from the surrounding rooms with a punch of an accent color to match the dining room chairs would be perfect.
