How many drywall screws per sheet.
If you drywall on 16 on centre studs with sheet length perpendicular to the studs and screw the two outside length edges at 6 spacing as it should be and the two interior studs at 12.

How many drywall screws per sheet.
So how many screws are needed per sheet of drywall.
For example if you have 1 600 square feet of drywall.
To determine the pounds of screws required divide the square footage of drywall by 300.

Figure on using about 32 drywall screws per sheet of 4 foot by 8 foot drywall installed horizontally on a wall.

If you have a stud that s 16 inches on center then this means you ll need around 50 when everything is evenly spaced.
This total is comprised of four screws on the five middle studs and six screws on each of the two sides.
If you use drywall adhesive you may reduce the number of screws to one every 16 inches.
The general answer you should use at least one drywall screw every 10 12 inches.
