Drywall Calculator
Enter the total square footage of wall and ceiling area you need to cover and this drywall calculator returns how many 4×8 or 4×12 sheets to buy, an approximate screw count and gallons of joint compound. A waste factor handles cutoffs around doors, windows and odd corners.

Tell this paint calculator your wall area, how many coats you plan to apply and the coverage rating from the paint can, and it returns the exact and rounded-up gallons you need. Most interior latex paints cover about 350 ft² per gallon on primed walls.
