The correct answer is: 7 feet

The typical requirement for vertical clearance in passageways within buildings is 7 feet. This height is established to ensure that people can navigate through these spaces comfortably and safely without the risk of bumping their heads or experiencing other obstacles. Maintaining a clearance of 7 feet is particularly important in public and commercial buildings, where traffic may be higher, and diverse user demographics, including individuals of varying heights, are present. This standard also reflects considerations for accessibility and ease of movement, which are crucial in building design and compliance with regulations. While other heights may be specified for different scenarios or settings, 7 feet has become a widely accepted minimum for general passageways, ensuring functional use of these areas.
