Estimate how many drywall sheets you need for walls, rooms, garages, and remodeling projects.
Divide total wall area by the square footage of one drywall sheet, then round up.
Formula: wall area ÷ sheet area = sheets needed
| 4 × 8 | 32 sq ft |
| 4 × 10 | 40 sq ft |
| 4 × 12 | 48 sq ft |
Divide total wall area by the square footage of one sheet, then round up.
Yes. Add 10 to 15 percent extra for cuts, waste, and mistakes.
No. Subtract non-drywalled areas first for a more accurate estimate.
