Install Stair Railings questions, answered by experts

The maximum measurement between stair stringers is typically 18 inches on-center. However, the International Building Code only requires that a staircase can resist a live load of 40 pounds per square foot in residential construction.

Building exterior porch steps requires wood or material that can handle exposure to the outdoor elements. Use pressure-treated lumber for the stringers and pressure-treated cedar, outdoor-rated wood, or composite decking material for the rest of the structure.

Spiral staircases can be installed outdoors using weather-resistant materials, such as galvanized steel, aluminum, or treated wood. Outdoor installations may require additional coatings or finishes to prevent rust and decay, and costs may be higher due to site prep and exposure to the elements. Outdoor staircases must also comply with local building codes, which can affect the dimensions, handrail requirements, and load capacities to guarantee safety in all weather conditions.

The four-inch ball rule for railing is a rule of thumb used when installing or replacing railings on stairways and decks. It refers to the gaps that naturally occur between balusters or other infills in a railing system. The rule states that a four-inch sphere should be unable to pass through any of the gaps. This helps prevent the possibility of people or animals slipping through.

The most comfortable height depends on you and your household, but most railings are between 32 inches and 40 inches. To be more granular, disability requirements require railing heights to be between 34 inches and 38 inches high. For this reason—and to remain compliant—many people find these heights perfectly acceptable and stay within these ranges.
