Drywalling a 10 × 12 room
A 10 × 12-foot room with an 8-ft ceiling has about 472 sq ft of drywall once you cover the walls and the ceiling. At 4×8 sheets (32 sq ft each) with ~10% waste, that's roughly 17 sheets.
Sheets are only part of the bill. This room also needs about 2 boxes of joint compound, 590 ft of tape, and 472 screws. Materials plus labor at a standard finish come to about $951–$2,028 — and the taping and finishing, not the sheets, is where most of that goes.
What drives your cost
| Factor | Effect on cost |
|---|---|
| Drywall area | ~472 sq ft of walls and ceiling to cover |
| Sheet size | Bigger sheets (4×10, 4×12) mean fewer seams to tape, but are heavier to handle |
| Waste factor | Plan ~10% extra for cuts around doors, windows, and outlets |
| Finishing materials | Joint compound, tape, and screws scale with area on top of the sheets |
| Taping & finishing | The biggest labor cost — 3 coats of mud with sanding between each |
| Level of finish | Level 3 for texture up to level 5 for smooth, glossy walls changes labor a lot |

Drywall finishing tips
- Bigger sheets cut your seam count — fewer joints to tape means a faster, flatter finish — but they're heavy, so have a helper or a lift.
- Budget time for three coats of joint compound with sanding between each; rushing the mud is the fastest way to a visibly bad wall.
- Buy about 10% extra sheets for cuts and the occasional broken corner — running one sheet short mid-job is a costly delay.
- Match the finish level to the lighting: level 4 is fine for most rooms, but go level 5 where glossy paint or side light will show every flaw.
