What Size Screws to Hang 1/2” and 5/8” Drywall
When it comes to hanging drywall, choosing the right size screws is fundamental to achieving a strong, durable, and aesthetically pleasing finish. Understanding how to select the proper screws, particularly for 1/2-inch and 5/8-inch drywall, is crucial for both DIY enthusiasts and professional contractors. This article will explore the appropriate screw sizes, types, and some installation tips to help you effectively hang drywall.
Understanding Drywall Thickness
Drywall, commonly used in construction for walls and ceilings, comes in various thicknesses, with 1/2-inch and 5/8-inch being the most prevalent. The thickness of the drywall you choose primarily depends on the specific application. Typically, 1/2-inch drywall is used in interior walls and ceilings, while 5/8-inch drywall is preferred for areas requiring additional fire resistance or soundproofing, such as in multi-family dwellings and commercial spaces.
Choosing the Right Screw Size
When it comes to screw sizes for hanging drywall, the most commonly recommended screws are typically 1 1/4 inches for 1/2-inch drywall and 1 5/8 inches or 2 inches for 5/8-inch drywall.

. These screws provide adequate length to penetrate through the drywall and into the wooden stud without piercing too deeply, which could compromise the drywall’s integrity or create unnecessary damage.- 5/8-inch Drywall Use either 1 5/8-inch or 2-inch screws. The slightly longer length allows the screw to grip better into the studs, providing a secure hold that ensures the drywall remains in place over time. If the drywall is being installed in certain applications, such as ceilings, some contractors prefer 2-inch screws for added stability.
Types of Screws

There are various types of screws available for hanging drywall, but the most common are coarse-thread and fine-thread screws, with coarse-thread screws being the most widely used for wood studs. Coarse-thread screws are designed for maximum grip in softwoods, while fine-thread screws are better suited for metal studs.
In addition to the thread type, consider using drywall screws that have a bugle head. This design allows the screw to sink into the drywall surface without tearing or damaging the paper, resulting in a smooth finish that is easier to tape and texture later.
Installation Tips
- Screw Spacing When hanging drywall, it’s essential to space your screws correctly. For 1/2-inch drywall, screws should be placed approximately 12 inches apart on the edges and 16 inches apart in the field (the center section of the drywall). For 5/8-inch drywall, the same spacing will work, but some professional installers prefer to reduce the spacing to 12 inches in high-stress areas.
- Avoid Over-Sinking Ensure that screws are driven just below the surface of the drywall. This is known as “dimpling” and prevents cracking when you tape and mud over the seams. Over-sinking can create dimpled spots that are challenging to cover.
- Utilize a Screw Gun A screw gun with a depth-sensing nosepiece can help achieve consistent screw depth, ensuring that screw heads sit flush with the drywall surface without going too deep.
Conclusion
Selecting the correct screw size for hanging 1/2-inch and 5/8-inch drywall is essential for a successful installation. Using 1 1/4-inch screws for 1/2-inch drywall and 1 5/8-inch or 2-inch screws for 5/8-inch drywall will provide the necessary support and longevity. Coupled with proper technique and spacing, the right screws will ensure your drywall not only looks good but also stands the test of time. Whether you’re a seasoned pro or just starting, these tips will equip you for a successful drywall installation project.
