A dining table should be no more than 48 inches wide to make everything on its surface easy to access, with 24 inches per person factored into its perimeter.
A clearance of 36 to 44 inches around the table is required for easy flow of traffic.
Display pieces (e.g., curios, buffets, etc.) should be placed at least 24 inches apart.
Any rug placed underneath the dining table should extend at least 2 inches past the edge of the tabletop.
