The unobstructed width of pedestrian walkways must be a minimum of how many inches?

The correct minimum unobstructed width for pedestrian walkways is 36 inches. This width is established to ensure accessibility and safety for users, allowing for comfortable passage of individuals, including those with mobility aids such as wheelchairs. A width of 36 inches is typically recognized as sufficient to accommodate foot traffic and maintain an efficient flow, especially in commercial or public spaces where pedestrian activity can be high.

Wider options may be advantageous in settings with significant foot traffic, but 36 inches is the mandated minimum in many building codes and accessibility standards, including the Americans with Disabilities Act (ADA). This width helps ensure that walkways can be used effectively without obstruction, thus promoting compliance with safety regulations and accessibility considerations.
