Drywall Sheet Thicknesses (ASTM C1396 / GA-216)
Gypsum board (drywall/sheetrock) under ASTM C1396 and GA-216 standardizes panel thicknesses for interior partitioning, sound isolation, and fire protection. Standard residential walls use 1/2-inch (12.7 mm) panels, while 5/8-inch (15.9 mm) Type X gypsum board incorporates glass fibers and vermiculite to achieve certified 1-hour fire ratings on garage walls and multi-family party partitions.

Door Rough Opening Dimensions & Sizing
Door rough openings are standardized framing openings in wood and steel stud walls engineered to accept pre-hung door frames, shims, and finished jambs. Under standard architectural guidelines, rough opening width is calculated as Nominal Door Width + 2.0 inches, and rough opening height is calculated as Nominal Door Height + 2.5 inches, with standard 36×80" doors accommodating ADA accessibility.

Door Butt Hinge Dimensions (ANSI/BHMA A156.1)
Standard door butt hinges under ANSI/BHMA A156.1 standardize hinge leaf dimensions, corner radius mortises, leaf thickness, and screw hole template patterns. Sized in 3.5×3.5" for 1-3/8" residential interior doors, 4.0×4.0" for 1-3/4" solid doors, and 4.5×4.5" for commercial ball-bearing fire doors, hinges maintain standardized spacing along door edges.
