How wide is a stair landing?

A stair landing is typically at least as wide as the staircase it serves, which is usually around 3 to 4 feet (0.9 to 1.2 meters) for residential stairs. However, building codes may vary, and some guidelines suggest that landings should be at least as wide as the stairs and provide enough space for safe movement. In commercial settings, landings might be wider to accommodate more foot traffic. Always consult local building codes for specific requirements.
