The 3 Standard Drywall Screw Sizes to Know in 2026

Choosing the wrong-sized screw can drastically affect your home improvement projects.

You will need to pay attention to your drywall screw sizes to ensure the project goes as smoothly as possible.

Drywall Screw Sizes in a Nutshell

The length of a drywall screw depends on your drywall’s thickness.

A thicker wall will require a larger screw, and a thinner piece of drywall can do with a smaller one.

Drywall screw sizes vary in length and diameter to effectively pierce through drywall without weighing it down. The most common screw lengths are 1-1/4, 1-3/8, and 1-5/8 inches.

If you have thicker drywall, you’ll want a longer screw that you can screw through the material and anchor on the other side. Drywall screw sizes also vary in diameter. The most common diameters are 6 (0.1380 inches) and 8 (0.1640 inches).

The thickness of the screw determines its strength. When you’re buying drywall screws, the packaging will list the length first and the diameter second, in this format: 1-¼” x 6”. 

You can use the following measurements to determine the appropriate length of drywall screw for your project:

  • 1-¼ inch screws for ¼ inch drywall
  • 1-⅜ inch screws for ½-inch drywall
  • 1-⅝ inch screws for ⅝ inch drywall

Why Do Drywall Screw Sizes Matter?

Your drywall screw size matters because you want to select the appropriate length for your drywall. A screw that is too short will not be able to anchor into the wall correctly, and a screw that is too long can damage the interior of your walls.

Furthermore, you want to choose the correct diameter for the best support (6- and 8-inch screws will work for most home projects). 

Why Use Drywall Screws? 

Historically, drywallers used nails to fasten drywall to wood, but over time, these nails pop out, causing unseemly bumps in your walls. Drywall pop led to the development of drywall screws.

These steel screws are more efficient, last longer, and don’t create lumps in your plaster. While screws in general work better than nails for drywall, drywall screws work better than wood screws because they use deeper threads.

Drywall screws are less likely to come loose than wood screws. Wood screws are also more expensive. Most importantly, drywall screws are more durable than wood screws. You will get better value and efficiency from these screws. 

The Different Kinds of Drywall Screws

Yes! As we’ve discussed, there are different types of drywall screws for wood and metal. 

  • S-Type: For attaching drywall to metal
  • W-Type: For attaching drywall to wood

Your home project will probably require W-type drywall screws. If you ever need to attach drywall to metal, an S-type screw is your go-to. These screws are sized in the same way, so review your drywall’s thickness to select the correct screw length. 

Are Longer Screws Better?

Buying the longest screws seems like a safer option. The screw should be too long rather than too short, right?

Unfortunately, this is incorrect. A long screw will pass through thin drywall and go deep into the wooden support structure of the walls.

If your screws go too deep into the wood, they’ll eventually succumb to popping. At this point, you’ll have run into the problem of ugly pops on your wall.

Always use the appropriate screw length for your drywall’s thickness. You’ll only want the screws to go ⅝-¾ inches into the wood. If you follow expert guidelines, you won’t have any issues. 

The most common problem that builders working with drywall screws face is popping, but other problems can arise from screwing too deep or puncturing the drywall. Because of this, the size of your screws is of the utmost importance.  

Things to Consider 

Remember, you can only fasten drywall screws into your walls with a screw gun or drill. 

  • Make sure your drill battery is charged
  • Attach the appropriate drill bit for the screws (drywall screws typically require a #2 drill bit)
  • Make sure your drill settings are set for drywall screws, if applicable
  • Make sure you are working with the drive setting rather than the removal 

Once you’ve got your drill and your screws, you’re ready to go!
