aisles

An aisle is a passage within a building or space that provides access between rows of shelves, seats, or other arrangements. Aisles enable movement and access while separating one area from another. They are common in retail stores, libraries, churches, theaters, airports, and transportation vehicles, and they can also refer to hallways within ships or large venues.

In retail and libraries, aisles are formed by vertical shelving units or stacks and are navigable corridors for customers and staff. They are often labeled or numbered to aid wayfinding and inventory control. In theaters and churches, aisles run between blocks of seating and may serve as processional routes. In airplanes, trains, and ships, an aisle is the central walkway that connects seating rows and cabins.

Design and safety considerations: aisle width affects maneuverability, visibility, and safety. Typical grocery-store aisles range roughly 0.9 to 1.2 meters in width, while accessibility codes frequently require a minimum clear width of about 0.9 meters (36 inches) for routes used by wheelchairs. Aisles should be kept free of obstructions, have appropriate lighting, signage, and non-slip flooring, and provide clear egress in emergencies.

Additional notes: the layout of aisles influences shopping behavior, crowd flow, and capacity planning. Advances in signage design, accessibility standards, and retail analytics continue to shape how aisles are arranged and maintained.
