For suggested seating always use about 60cm (24″) per person when determining the number of chairs that can be placed comfortably around a table. You should consider the leg style/placement, overhang, and width of the chairs. For those moments when you are entertaining more people allow for about 50cm (20″) extra in length. Alternatively, extenders of 50-60cm (20-24″) can be used to extend the table for extra seating.
