What size opening do I need for a spiral staircase?
3’6” translates to 42 total inches in diameter and therefore the MINIMUM opening size that you need MUST be 44 inches x 44 inches (44”x44”). You need at least 44”x44” opening because you’ll need two extra inches for your fingers to travel along the handrail as you walk up and down the stairs.
