2 x 10 Stair Stringers
2 x 10 stair stringers are not the best choice for building stairs. If the stairs are only 3 to 5 steps and the stringers are cut carefully so that there aren't any knots or cracks in this 5 to 6 inch area creating a weak spot. This would be ok but not recommended. Use a 2 x 12 stair stringer as a minimum for safety.
