ceiling drywall calculator. Sheet count for ceiling installation with joint compound and screws.
The Short Answer: A 12x14 ceiling needs 6 sheets of 4x8 drywall or 4 sheets of 4x12. Use 4x12 sheets on ceilings whenever possible — they span the full width with fewer joints, which means less taping and a smoother finish.
Ceiling Drywall Tips
Ceiling drywall installation is harder than walls -- gravity is working against you, and every imperfection is visible in raking light. Use 4x12 sheets (not 4x8) whenever possible: they span the full width of most rooms with fewer joints, which means less taping and a smoother finish.
Ceiling drywall should be installed before wall drywall -- the wall sheets support the edges of the ceiling sheets. Use screws every 8 inches on ceiling joists (tighter than the 12-inch spacing for walls) because gravity pulls harder. A drywall lift ($40-60/day rental) is essential for ceilings -- holding a 90-pound 4x12 sheet overhead while driving screws is a two-person job minimum without one.
