Drywall screw spacing: walls vs. ceilings
For typical non-fire-rated USG gypsum panel applications, the cited guide sets maximum screw spacing at 16 inches on walls and 12 inches on ceilings. Check the selected panel and assembly instructions.
Quick answer: how far apart should drywall screws be?
USG's guidance for screwing gypsum panels to wood or steel framing in non-fire-rated assemblies gives maximum spacing of 16 inches on walls and 12 inches on ceilings. These are maximum distances along framing members, not the spacing between studs or joists. The applicable panel instructions or a required assembly can specify different details.

Are wall and ceiling screw spacings different?
The cited USG guide specifies a 12-inch maximum on ceilings and a 16-inch maximum on walls. Treat these as the guide's installation limits for the described application, not as a universal rule for every panel, framing condition or assembly. Check the instructions for the exact board and project.
How close can a screw go to a panel edge?
USG says to place screws at least 3/8 inch from panel ends and edges. Follow the selected panel's current installation instructions if they give a different requirement.
How deep should drywall screws go?
USG's guide says to sink the screw just below the panel surface while leaving the paper intact. A torn paper face is not the finish condition described in that guide. Use an adjustable depth-control screwgun and check the board manufacturer's current instructions.
Does this spacing apply to nails or fire-rated walls?
No. USG lists different maximum spacing for nails in wood framing: 8 inches on walls and 7 inches on ceilings. For fire-rated construction, USG directs installers to the relevant fire test; use the specified assembly's panel, framing, fastener type and spacing rather than applying this general non-fire-rated guidance.
How do I estimate the drywall materials for my project?
Use the drywall sheet and materials calculator linked below for an area-based sheet and finishing-material estimate. It does not determine fastener layout, code compliance or a fire-rated assembly.
