Drywall Length and Width
The dimensions of drywall sheets are typically in multiples of 4 feet. Commonly, you’ll find 4-foot by 8-foot, 4-foot by 12-foot, or 4-foot by 16-foot sheets. While the lengths can vary, the width usually remains at 4 feet.
Building codes specify the thickness of drywall sheets, but not their width or length. These dimensions are determined based on the needs of the architect, builder, and client.
4-Foot by 8-Foot Drywall
The most frequently used size of drywall is 4 feet wide and 8 feet long. These 1/2-inch thick sheets weigh approximately 57 pounds, making them manageable for most do-it-yourselfers.
The 4-foot by 8-foot sheets allow for both vertical and horizontal installation. Often, these panels are paired, bound by paper strips, making them challenging to carry alone. You can remove the binding paper for easier transport.
4-Foot by 12- or 16-Foot Drywall
For taller or longer walls, you can find drywall in 12-foot and 16-foot lengths. Longer sheets provide a smooth vertical surface for higher ceilings, creating an unbroken wall from floor to ceiling.
Sixteen-foot drywall, when installed horizontally, minimizes butt joints compared to 8-foot sheets. Installing 16-foot sheets may require additional help due to their size.
2-Foot by 2-Foot Drywall
A 2-foot by 2-foot square of drywall is not a standard size but can often be found as cut-down pieces in local hardware stores. These small sheets are handy for patching or wall-boarding small spaces.
Alternative Sizes of Drywall
When you encounter drywall in lengths or widths other than multiples of 4 feet, it may not be traditional drywall but could be cement board or an alternative like DRIcor Smart wall.
Although less common, you can special-order 4 1/2-foot-wide drywall sheets, primarily used by professionals and not stocked in home improvement centers.
Thickness of Drywall
Common drywall thicknesses include 1/4-inch, 1/2-inch, and 5/8-inch. Building codes dictate the required thickness for different applications.
1/4-Inch-Thick Drywall
While not typical, 1/4-inch-thick drywall is useful for skimming or covering existing surfaces or for bending to fit slightly curved areas.
One practical application is covering textured ceilings without removing the texture.
1/2-Inch-Thick Drywall
For most interior walls and ceilings, 1/2-inch drywall is the standard thickness. It’s relatively easy to handle and install, making it the default choice for wall applications.
Ultra-light 1/2-inch panels, 13 pounds lighter than regular 1/2-inch drywall, are even easier to carry.
5/8-Inch-Thick Drywall
5/8-inch-thick panels are commonly used for ceilings and walls that require a fire-resistant rating. They are less prone to sagging between joists, especially when combined with heavy surfacing materials like popcorn texture.
Some applications call for multiple layers of drywall, enhancing sound resistance and sturdiness.
3/4-Inch-Thick Drywall
The practical maximum thickness for drywall is 5/8-inch, but 3/4-inch drywall is used on steel-framed walls for fireproofing. Walls must be able to support 3/4-inch drywall, which can weigh up to 112 pounds for 4-foot by 10-foot sheets.
Fire-Rated 5/8-Inch Thick Drywall
5/8-Inch-Thick Type X Drywall
Thicker drywall may be required by building codes for surfaces with a texture or skim coat when studs or joists are spaced 24 inches on-center, rather than the standard 16 inches. Type X drywall, thicker and fire-resistant, is often used for walls.
Type X drywall contains proprietary additives, mainly glass fibers, that enhance its fire resistance.
5/8-Inch-Thick Type C Drywall
Like Type X, Type C drywall is fire-rated and contains a high quantity of glass fibers. However, Type C also incorporates vermiculite to prevent shrinking. It is more commonly used on ceilings.
