heightlength

Heightlength is a nonstandard, informal term used to describe an object's size in two dimensions by reference to its height and its length. It is not listed in formal dimensioning standards and is most often found in catalogs, shipping notes, or design workflows where a two-axes description is convenient.

Interpretations vary. In some contexts heightlength simply stands for the pair (height, length). In others, it is used to denote a single “overall” size when comparing objects, though such usage is ambiguous because it omits width or depth. Because heightlength is not standardized, it is important to specify both height and length explicitly and to clarify what is meant by heightlength in any document.

Applications include product packaging and shelving, where heightlength can indicate how tall and how long a package is for planning stacking, storage, and display. In 3D modeling and CAD, heightlength may be used as part of bounding-box descriptions along two axes. In data catalogs, a heightlength field may accompany other size attributes such as width and depth.

Etymology-wise, heightlength is a portmanteau formed from height and length; it is not a term with formal recognition in major standards bodies. See also dimensions, height, length, bounding box, packaging.
