Final answer:
Revolving doors need to be capable of safe, efficient traffic flow and have a minimum width of 32 inches. Size requirements could be as much as 8 diameters in width and 15 diameters in depth based on newer standards.
Step-by-step explanation:
Revolving doors should be capable of accommodating safe and efficient passage for building occupants and have a width of at least 32 inches to comply with accessibility standards. When considering the overall design and size of the doorway, it's important not only to account for the width of the door, but also the requisite clearance to ensure safety and comfort for all users. An older "rule of thumb" for door width was 5 diameters side-to-side and 7-8 diameters deep. However, recent studies suggest that a revolving door may require as much as 8 diameters side-to-side and 15 diameters deep to ensure ample space and efficient flow of traffic.
Revolving doors should be capable of rotating and have a width of at least 15 inches. The older "rule of thumb" suggests a width of 5 side-to-side and 7-8 deep, but newer work recommends a width of up to 8 diameters side-to-side and 15 diameters deep. These guidelines are based on the efficiency and comfort of the revolving door.
