Drywall for a 10 × 11 ft room
With 8 ft ceilings, the walls are 336 ft² and the ceiling 110 ft². Sheet counts include 10% waste; supplies are rules of thumb.
| What you hang | Area | 4×8 sheets | 4×12 sheets | Joint compound | Joint tape |
|---|---|---|---|---|---|
| Walls only | 336 ft² | 12 | 8 | 3.4 gal | 124 ft |
| Walls and ceiling | 446 ft² | 16 | 11 | 4.5 gal | 165 ft |
| Ceiling only | 110 ft² | 4 | 3 | 1.1 gal | 41 ft |
Hanging tips
Hang the ceiling first, then the walls, running sheets horizontally. Stagger the joints, use about one screw per square foot, and tape and mud every seam in three coats. Use moisture-resistant board in bathrooms and fire-rated (5/8 in Type X) in garages and next to furnaces. See the drywall calculator to adjust for your ceilings.
Hauling, studs and screws
A ½ inch 4 × 8 sheet weighs about 55 lb, so the 16 sheets for the walls and ceiling weigh roughly 880 lb (0.44 tons). Most pickups can take a few sheets flat, but a full order is a delivery, or several trips. Carry them on edge, and use a helper.
The walls are 42 ft around, which is about 36 studs at 16 inch centers (the corners add a few). Plan on roughly one screw per square foot, which is 512 screws for this order.
A 10 × 11 room: odd lengths, so save the cutoffs
A 10 × 11 room with an 8 ft ceiling comes to 16 sheets of 4 × 8 drywall for walls and ceiling, and 12 sheets for the walls only.
Neither wall length is a multiple of 4 ft, so every wall ends in a cut piece. Use the cutoff from one wall to start the next course, keeping factory tapered edges together and cut edges into the corners where the tape hides them. The ceiling is 110 sq ft: run the sheets across the joists and stagger the end joints so they do not line up from row to row.

Frequently asked questions
How many sheets of drywall for a 10x11 room?
16 sheets of 4 × 8 ft for the walls and ceiling with 8 ft ceilings and 10% waste, or 12 for the walls only. With 4 × 12 ft sheets it is 11 for both.
How much joint compound for a 10x11 room?
About 4.5 gallons for the walls and ceiling as a rule of thumb (1 gallon per 100 ft²), so one 4.5 gallon box is enough.
Do I subtract windows and doors for drywall?
Not usually. The cut-outs are offset by the waste allowance, and you need the cutoffs for filling around openings.
