How Many Drywall Sheets Do I Need for a 12x12 Room?

Quick Answer

A 12x12 room with 8-foot walls needs about 12 sheets of 4x8 drywall for the walls, or about 17 sheets if you include the ceiling.

Use the [Drywall Calculator](/drywall-calculator) to adjust the dimensions, waste factor, product coverage, and unit price for your exact project.

Formula

``

Sheets = total surface area / sheet area

``

Example Estimate

1. Wall area is 48 ft perimeter x 8 ft height = 384 square feet.

2. Ceiling area is 12 x 12 = 144 square feet.

3. Total with ceiling is 528 square feet.

4. 528 / 32 = 16.5, so round up to 17 sheets.

Reference Table

| Scope | 4x8 sheets |

|---|---:|

| Walls only | 12 |

| Ceiling only | 5 |

| Walls and ceiling | 17 |

Practical Tips

- Hang ceilings before walls.

- Use 4x12 sheets when practical to reduce seams.

- Do not forget screws, tape, mud, and corner bead.

When to Round Up

Round up when the project has cuts, corners, fragile materials, uneven surfaces, delivery minimums, or any chance that matching the same product later will be difficult.
