There are some guidelines on how many people an outdoor table will accommodate and how it will fit into your Jacksonville backyard space. A typical Bistro table - at 26" around, will seat just two, a 48" round or square table will seat four to six, and a 60" to 72" table normally will seat up to eight. Side chairs average 17" in width and depth and armchairs can be as much as 25" wide and deep.
Although tables tend to stay put, chairs are often pushed in and out and around the patio. A good guideline is to add the total width of your table and leave at least 3 feet on each side to allow movement of all your guests. If there are steps or a terrace ledge nearby, be sure to leave at least 5 feet for safety and comfort.
