Aisles are narrow passageways in stores, supermarkets, or warehouses that allow customers to navigate between shelves or displays. They are designed to organize products and make it easier for shoppers to find what they need. Aisles can vary in width and length, depending on the layout of the space and the type of products being sold. In addition to retail environments, aisles are also found in places like airplanes, theaters, and libraries. In these settings, aisles help facilitate movement and access to seats or sections. Properly designed aisles enhance safety and improve the overall experience for users.
