A range that a person can stretch to touch or grasp an object from a specified position.

Explanation:
Reach is the maximum distance a person can extend from a starting position to touch or grasp an object. It blends arm length, shoulder mobility, and posture, and is essential when designing where controls, handles, and displays are placed so they’re accessible without overreaching. Perception deals with sensing and interpreting information, not how far someone can reach. Range of sizes refers to the variety of body or object sizes, not the distance someone can stretch. Secondary data is information gathered from existing sources, not a person’s physical capability.
