Best Answer: 600mm is the minimum width only if the stair allows access to one room (normally an attic stair) If it is more than one room then the minimum width is 840mm, but 860 is more standard. These sizes ignore intrusions like stringers, skirting and newels. So from wall to handrail.
minimum clear width of a stairway at or below the handrail, when one is required, is 31 Â½ inches, and 27. inches where two are required. Stair trim, stringers and other features may reduce the stairway width as. long as they do not extend beyond the allowable handrail projection. There is a width exception for. spiral stairways. The maximum riser height is 8 Â¼ inches and the minimum tread depth is 9 inches. Open risers are permitted provided the vertical opening between treads does not permit the passage of a. 4-inch-diameter sphere in stairways which have a rise exceeding 30 inches.
