In addition, a round table takes up less space than a rectangular one, as the curved edge optimizes the surface area. In order not to play “eating on the airplane,” with elbows bumping into each other, a rule of thumb is to give each person 24 inches of space so that they can sit comfortably (this does of course also depend on the chairs). A table with a diameter of 60 inches gives 186 inches of circumference, enough space for eight people. A table 48 inches in diameter seats five people.
