Building a stairwell what are dimensions?
that would depend upon the distance between floors. with a distance of approx. 9' it would be around 37" wide and 8' long. The floor to floor height is only 1/3 of the solution for figuring out the stairwell length. That, with the tread, will give you the angle of the staircase. The less slope of the stairs, the bigger the well size needs to be for headroom clearance at the bottom. The other thing that needs to be figured in is the thickness of the floor system. The taller the joists, the sooner you'll hit your head and so the stairwell will need to be longer. For instance, 7 3/4"riser, 10"tread and 2x10 joists the well size needs to be 118 1/2" from the stair nosing edge to the head joist. For 2x12 joists it's 121". You'll need to add a little to this depending on how you hang your stingers for the actual framing of the stairwell. Check out stairwell-lengths.com for a book on all stairwell lengths for every angle and joist size.
