One point to keep in mind when choosing a table is how it will influence the social factor of your dining room. A round table is perfect for when you want to encourage conversation around the dining table. Also, it doesn’t allow anybody to sit at the head of the table, which is perfect for when you want to avoid any type of hierarchy.The same is true for square tables; however, square tables take up more space than round ones. And for the same number of diners, it’s better to opt for a rectangular one, as it offers more seating areas.
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.
