The IBC maximum rise of a single stair flight is 12. The nosing is the protrusion at the edge of a tread that hangs over the riser below. The wider they are the better because they are safer.

This rule can be applied to any staircase design its 11 inches and that would consist of a 10 inch run in the individual stairway and a 1 inch.
