Why Screw Spacing Matters
Improper screw placement is the #1 cause of nail pops and sagging drywall. This guide gives you the exact patterns required by the IRC (International Residential Code) and common best practices. Whether you're hanging 4×8 or 4×12 sheets, on walls or ceilings, you'll find the right spacing here.
Use the interactive chart below to see screw counts and spacing for your specific setup. Adjust stud spacing and panel orientation to get a custom pattern.

* Ceiling installations require screws every 12" on all framing members regardless of stud spacing. For walls with 24" stud spacing, use 12" field spacing to prevent sag.
Pro Tips for Perfect Drywall
- Use the right screw length: 1-1/4" for 1/2" drywall, 1-5/8" for 5/8" drywall.
- Dimple, don't break the paper: Set screws just below the surface without tearing the facing.
- Stagger joints: Offset end joints on adjacent rows by at least 16" for strength.
- Butt joints on framing: Always land butt ends on a stud or joist.
- Adhesive + screws: For ceilings, use construction adhesive in addition to screws to reduce pops.
