As mentioned, rectangular tables present a certain advantage in terms of capacity that round- and square ones do not. Imagine having to place all the diners to be seated at this elongated table at a round one – you’d have to have a pretty big round table!. For big dinner parties, it’s best to opt for an elongated/rectangular table, as you get more space for chairs and guests.
The rectangular tables are the most common, which shows that they are a practical, functional and comfortable option. They are perfect for elongated dining rooms and they allow for more diners in less space. In a small room, a rectangular table can be shoved against the wall and still be perfectly practical.
