Good Morning Joyce! Thank you for your interest in Trex! The maximum stringer spacing for stairs for the Enhance Basics Clam Shell boards is 9" on center. We do have a decking installation guide with this information, please call us at 1-800-289-8739 and we would be happy to discuss installation information and get you a copy of our installation guide. Thanks! - Paul, Trex Customer Care
