1. Width: The width of a hallway should be wide enough to comfortably allow two people to walk side by side. A minimum width of 36 inches (91 cm) is recommended, but wider hallways (42 inches or 107 cm) are more comfortable.
2. Height: The height of a hallway should be tall enough to allow people to walk comfortably without feeling cramped. A minimum height of 7 feet (2.13 m) is recommended.
3. Doorways: Doorways along a hallway should be placed in a consistent manner and should be wide enough to allow furniture and other large objects to be moved through easily. A standard door width is 36 inches (91 cm), but wider doors (42 inches or 107 cm) may be used for main entryways or if the hallway is particularly wide.
4. Clearance: There should be adequate clearance between walls, doorways, and other obstacles in the hallway to allow people to move around safely and easily. A minimum clearance of 30 inches (76 cm) is recommended on either side of a walkway.
5. Lighting: The hallway should be well-lit to ensure safety and visibility. This can be achieved through natural light from windows or by using artificial lighting fixtures.
6. Storage: If needed, storage space can be incorporated into the hallway through the use of built-in closets, cabinets, or shelves.
It's important to note that these dimensions are just guidelines and may need to be adjusted based on specific requirements and preferences. Additionally, local building codes and regulations may have specific requirements for hallway dimensions, so it's important to check with your local authorities before finalizing any plans.
