Sheet count calculator
Add rooms and walls and get a sheet count, with scrap reused the way a crew would.
Open sheet countEvery drywall price starts with the same thing: an accurate sheet count. Square footage of wall and ceiling surface, not floor area, drives the material order, the labor, and the final number on a quote. The pages here follow the order a contractor works in. First measure the walls and ceilings and turn that into a sheet count. Then add fasteners, mud and tape, including material delivery costs. Finally, apply rates for each part of the work: hanging, taping and finishing, and texture.
If you are a homeowner, these pages explain where a contractor's number comes from. They help you compare quotes on the same basis. Prices for board and labor change by city and by year, so this section explains the method rather than quoting prices. Check local supply prices and get more than one quote.
If you price drywall for a living, the calculators below speed up sheet count estimates. The sheet count calculator lays out rooms the way a hanging crew would and reuses scrap, so the number matches what you will actually order.

Open fastener spacingBoth. Large jobs are usually priced per square foot of board hung and finished. Small jobs and patches are often priced by the day or as a flat minimum. Per-sheet pricing uses the same math: a 4x12 sheet covers 48 square feet, a 4x10 covers 40 and a 4x8 covers 32.
Measure the surface area of every wall and ceiling, not the floor area, and divide by the area of the sheet size you plan to use. Leave window and door openings in the total, because the cutouts become scrap. The sheet count calculator does this room by room.
No. Drywall square footage is the surface area of the walls and ceilings, which is usually several times the floor area of the house.
Supply prices are fairly consistent between distributors. Quotes differ because of how each contractor marks up material, the labor rates they need to cover, and services such as stocking board inside the house.
