Frequently Asked Questions
A standard 4x8 sheet usually requires about 32 screws (spaced 12-16 inches apart on studs).
A general rule is about 0.05-0.06 lbs of compound per square foot of drywall, or roughly 5 gallons for every 500 sq ft.
4x8 is standard for most residential walls. 4x10 or 4x12 are used to minimize joints on longer walls or higher ceilings.
