Enter room dimensions to calculate materials
Installing drywall (also called sheetrock or gypsum board) is a fundamental construction skill. Our calculator helps estimate materials needed for any room size, accounting for doors, windows, and cutting waste. Proper material estimation prevents delays and extra trips to the store.
Hang sheets horizontally for fewer seams. Stagger joints for strength. Use 10-15% extra for waste. Three coats of joint compound needed: tape coat, fill coat, finish coat.
