Work out drywall sheets plus jointing tape, compound and screws for walls and ceilings.
UK note: drywall is called plasterboard in the UK. If you just need a sheet count and a cost estimate, try our Plasterboard Calculator.
Measure total wall area, subtract openings, divide by sheet area (32 sq ft for 4×8), and add 10% for waste.
About 28-32 screws per 4×8 sheet, spaced every 12 inches along studs.
1/2 inch (12.5 mm) is standard for walls. 5/8 inch (15 mm) for ceilings or fire-rated applications.
Yes. "Drywall" is the American term and "plasterboard" is the British term for the same gypsum board. If you want a simple sheet count plus a cost estimate, use our Plasterboard Calculator instead.
As a rough guide, allow around 1 gallon (about 3.8 litres) of ready-mixed compound per 100 sq ft of board and roughly 12 ft of tape per sheet. This calculator estimates both for you.
Estimate how much plaster you need for walls and ceilings, the number of bags and the total cost in metric or imperial units.
