Drywall Sheet Sizes
4 × 8 feet
Standard size. Good for 8-foot ceilings. 32 sq ft per sheet.
4 × 10 feet
For 9-10 foot ceilings. Reduces horizontal seams. 40 sq ft per sheet.
4 × 12 feet
For high ceilings. Fewer seams, harder to handle. 48 sq ft per sheet.
Installation Tips
- • Hang ceiling drywall first, then walls
- • Stagger seams between rows for stronger walls
- • Use 1-1/4" screws for 1/2" drywall, 1-5/8" for 5/8"
- • Space screws 12" apart on ceilings, 16" on walls
- • Store drywall flat to prevent warping
