For the whole job.

Usage Tip

Buy screws by the pound and keep extras; stripped or overdriven screws get replaced as you go.

THE MATH
screws = sheets × screws per sheet
Drywall is fastened on a grid, so screw count scales with the number of sheets and the spacing the application calls for. Ceilings need more screws than walls.
Enter the number of drywall sheets and choose the application.
Walls use about 32 screws per sheet, ceilings about 36, and lightweight or thin walls about 28.
