We started talking with a couple about how they wanted their dining room to function and we got into a detailed conversation about dining room furniture. 

When choosing your dining room furniture, you should start with the dining room table.

The first thing you'll need to consider is shape. Choosing the right shape for your dining room table is going to set you on the right path toward maximizing the room's space and creating the best atmosphere for your home.

Specific considerations for these different shapes are discussed below, but also remember to consider what, if any, auxiliary uses you might have for dining room. Some homeowners use the dining room as their home office as well. Others may use it as a sitting room, either for reading or entertaining. Is it more important that your dining room provides a daily dining area for your family? Or do you need a more formal area for guests and parties?

Round Dining Room Tables

A round dining room table is the most space-efficient shape possible. It is also the least formal. You should consider choosing a round table if you have a smaller dining room. Realize, also, that a round dining room table doesn't create a "head of the table." This can be a plus for casual and family dining and for diffusing power relationships in stressful family or business settings. If you like to play cards or board games, a round table will allow everybody to reach the middle of the table.

Square Dining Room Tables

Similar to a round table, a square dining room table creates a bit more formal atmosphere but sacrifices the use of extra space in the room. A moderately-sized, square dining room best accommodates this shape. Not entirely casual, but not entirely formal either, couples who like to entertain their coupled friends may find this table ideal. Each couple can have their own side of the table and nobody has a privileged place. A square dining room table is another good table for games.
