Drywall length and width generally works on the “four foot unit” system. So, widths and lengths will typically be a multiple of four feet. Code does not dictate drywall length and width; these are determined by the needs of the builder, architect, and client. Code does dictate some drywall thicknesses, though.
|Length||Length ranges from 8′ to 16′.|
|Thickness||From 1/4″ to 5/8″. Thickness is variable and often code-related. For example, code requires that thicker Type X drywall be installed on garage walls that are adjacent to the house. See below for details.|
