How Many Screws Per Sheet of Drywall?
Part of Interior & Finishes
Quick answer
Use about 32 screws per 4×8 sheet on walls (16 inches apart in the field, 8 inches on edges) and around 36–40 on ceilings, where screws go every 12 inches. That's roughly one 1 lb box per 8–10 sheets.
Screw count comes straight from spacing. Closer spacing on ceilings — to fight gravity and sag — means more screws per sheet than on walls.
Spacing and screws per 4×8 sheet
| Location | Field spacing | Screws per sheet |
|---|---|---|
| Walls | 16 in | ~32 |
| Ceilings | 12 in | ~36–40 |
| Fire-rated assembly | Per code (often 8–12 in) | 40+ |
- Keep screws at least 3/8 inch from the edge so the paper doesn't tear.
- Drive heads just below the surface (a dimple) without breaking the paper.
- Use 1-1/4 inch screws for 1/2 inch board, 1-5/8 inch for 5/8 inch board.
- A 1 lb box holds roughly 300+ screws — about 8–10 sheets' worth.
