AStart with your required seating count: at standard spacing of 30–36 inches per seat, a 6-foot table seats 4–6 people, an 8-foot table seats 6–8, a 10-foot table seats 8–10, a 12-foot table seats 10–12, and a 16-foot table seats 14–16. Then verify the room can accommodate the table with proper clearance: allow a minimum of 48 inches from the table edge to the nearest wall on all seated sides for chair pushback and circulation (60 inches recommended for wheelchair accessibility). A common mistake is choosing a table that fits the room on paper but leaves insufficient clearance for chairs and movement.
