L×W×H

L×W×H is a common notation for the three linear dimensions of a solid object or space, representing length (L), width (W), and height (H). These dimensions describe the extent of an object along its three principal axes. The product L×W×H is used to compute the object's volume, expressed in cubic units such as cm³ or m³.

The convention assigns L as the longest horizontal dimension, W as the other horizontal dimension, and H as the vertical dimension, but the exact labeling can vary by field or region. In some contexts depth is used instead of width, leading to L×W×D. Because orientation can change with rotation, the numerical values of L, W, and H depend on how the object is aligned relative to a coordinate system.

Applications include packaging and shipping (dimensional measurements determine space and sometimes dimensional weight), furniture and product design, construction, and 3D printing, where a printer’s build volume is specified as L×W×H. In computer graphics and 3D modeling, L×W×H often describes the bounding box or voxel grid dimensions of a model or scene.

Volume is calculated by multiplying the three dimensions: V = L × W × H. Consistency of units is essential; mixing meters with centimeters, for example, requires conversion. A bounding box that is 10 cm by 20 cm by 30 cm has a volume of 6000 cm³ (equivalently 0.006 m³). Understanding L×W×H helps compare sizes, plan storage, and assess fit within a given space.
