A round table that is 60 inches in diameter typically seats eight adults comfortably. If the adults sit close together, the table can adequately accommodate 10 adults. This is based on the typical 16- to 18-inch seat widths available at banquet halls and conference centers.
When eight people are seated at a 60-inch table, each person has about 12 square feet of room. When 10 people are at the table, each person has approximately 10 square feet of individual space.
To cover a 60-inch round dining table completely, the host needs a 120-inch cloth that overhangs to the floor. A 90-inch cloth covers the tabletop and provides a 15-inch overhang.
