While 5.5 x 3.5 would be sufficient in some instances 6x6 is the prefered size even it is stronger than necessary. That said there is not a one size fits all when it comes to balconies or any wood framed structure. As the height and size increases so does the size of the support. . While 6x6 is good for 3 to 4 feet some municipal and county codes in California may be stricter. Six by six would be closer to the correct size but only to the limited height or length of the support. In most cases 3 feet
to 4 feet. The number used and the span placed on them (distance apart) also determines the size. Eight by eight,
and ten by ten and so on as the height increases.
Your answer is not a yes no or either or situations as heights and sizes vary. That said 6x6 would ve the minimum.
NOTE: if six by six framing is used beyond four feet alternate knee bracing is required in California . This may interfere with the design of the balcony requiring the use of larger materials.
