What size should a dining table be to comfortably seat 8 people?

To comfortably seat 8 people, the dining table should be around 36 x 78 inches (91 x 198 cm) in size. This will allow each person to have enough elbow room and space to eat comfortably. If you want to also have space for serving dishes or platters, you may want to consider a larger table, such as one that is 42 x 84 inches (107 x 213 cm).
