A 72-inch round table is typically the best pick for seating 8 people comfortably. This size allows for enough space to accommodate 8 place settings and provides adequate elbow room for each person. If you’re limited on space, A 60-inch round table can also seat up to 8 adults, but keep in mind it won’t grant individuals as much personal space a a 72-inch table. One important element to keep in mind when selecting a table size is your dining chairs. Calculate their width to ensure that they won’t look too squeezed if you select a smaller circumfrence table.
