In mathematical analysis and geometry, a **rectifiable set** refers to a set in Euclidean space (or a more general metric space) that can be approximated in terms of its length, area, or volume in a well-defined way. The concept is closely associated with the idea of measuring the "size" of a set in terms of lower-dimensional measures.
