What is the thickness of wood?

The thickness of wood can vary widely depending on its intended use and type. Commonly, lumber is sold in standard dimensions, such as 1x4 inches, which actually measures about 0.75 inches thick after drying and planing. Plywood and engineered wood products come in varying thicknesses, typically ranging from 1/8 inch to several inches. For specific applications, such as furniture or cabinetry, the thickness may be tailored to meet design and structural requirements.
