How Many Screws Per Sheet of Drywall? (Plus a Handy Drywall Screw Calculator)

If you're tackling a drywall project, one of the most common questions is: “How many screws do I need per sheet?” Whether you’re hanging walls, ceilings, or patching up repairs, using the right number of screws ensures stability and avoids sagging.

How Many Screws Do You Need?

For a standard 4' x 8' drywall sheet, the general rule is:

• Walls: 28–36 screws (spaced every 12 inches)

• Ceilings: 36–48 screws (spaced every 8 inches for added support)

The actual number depends on:

• The stud spacing (16" vs 24")

• Whether you’re attaching to wood or metal

• Ceiling vs wall applications

💡 Tip: Always check local building codes for exact spacing requirements.
