Description

Stair widths in construction are crucial in ensuring safety, accessibility, and efficient flow of foot traffic. In residential settings, stairs are generally narrower, catering to fewer occupants. Conversely, in commercial or public buildings, wider stairs are necessary to accommodate a larger number of people and to facilitate swift evacuation in emergencies. In venues like theaters or stadiums, where there is high foot traffic, even wider stairs are needed. Additionally, stair width must account for individuals using mobility aids, ensuring their safe and unhindered passage. Local building codes often dictate specific requirements for stair widths.

For stairs serving a single user (typically private residential), a minimum of 36” (91 cm) is required. In general public spaces a minimum of 44” (112 cm) must be met—providing ample space for one person and allowing the tight passage of two people. Comfortable two person stair widths range between 49” (125 cm) to 60” (152 cm). For three simultaneous users, a minimum of 74” (188 cm) is recommended. Handrails must be placed every 60” (152 cm).
