Frequently Asked Questions
Should I use 4x8 or 4x12 drywall sheets?
4x8 sheets are lighter and easier to handle for solo DIYers. 4x12 sheets are preferred by professionals on long walls and high ceilings because they create 25% fewer seams to tape and finish.
How many drywall screws do I need per sheet?
A standard 4x8 drywall sheet requires approximately 32 screws on walls (spaced 16 inches apart along studs) and 36 screws on ceilings (spaced 12 inches apart).
How much drywall joint compound mud do I need?
A general rule of thumb is approximately 0.053 gallons of joint compound per square foot of drywall. That equals roughly one 4.5-gallon pail for every 85 to 100 square feet of finished drywall (covering embedding, fill, and finish coats).
