The number of people you can seat at a table depends on its size and shape. Typically, a standard dining table can accommodate 4 to 12 people, with round tables often seating fewer than rectangular ones. For optimal comfort, allow about 24 to 30 inches of space per person. Always consider the available space and the size of the chairs as well.
