What is the maximum distance from the roof for the final nail in drywall?

• A. 6 in
• B. 8 in
• C. 10 in
• D. 12 in

Answer: (B)

Edge fastener spacing is critical when installing drywall. Near the ceiling, nails or screws should be placed no more than eight inches apart to keep the sheet pressed firmly against the framing and to prevent sagging or nail pops as the wood expands and contracts. This tighter spacing helps ensure the joint stays solid through finishing, painting, and use. In contrast, fasteners in the field away from edges are spaced farther apart, typically around 12 inches. So the maximum distance for the final nail from the ceiling is eight inches.
