This means your stair. Maximum nosing radius: 9in: Minimum tread depth in. COMMONLY USED RESIDENTIAL BUILDING CODES. Stair treads and risers.
Such headroom shall be continuous above the stairway to the point where the line intersects the landing below, one tread depth beyond the bottom riser. Click on this link for more information about stairway building codes.
MINIMUM TREAD DEPTHS: TREAD DEPTHS SHALL BE IN. Dimensional uniformity. Riser height and tread depth. As determined by the foregoing riser computation, the stair calls for sixteen 63⁄4′′ risers.
