Clearance in ergonomics is defined as:

Clearance in ergonomics refers primarily to the physical space between two objects, which is essential for ensuring comfort and safety in user interactions with their environment. Understanding clearance helps designers ensure that individuals have enough space to move freely without risk of injury or discomfort.

For instance, when designing workspaces, it's crucial to consider the clearance needed for an individual's body, as well as tools or equipment they may be using. Adequate clearance can prevent unnecessary strain or awkward postures that might arise from insufficient space. By focusing on the physical gaps between elements, designers can create environments that accommodate a wide range of body sizes and movement patterns, which is fundamental in ergonomic design.

This concept of clearance is significant in various contexts, such as in furniture design, workplace ergonomics, and product usability, where it contributes positively to user experience and efficiency.
