Drywall Cost Calculator
Use the drywall cost calculator below to get an instant material and installed price range for your project. To calculate drywall, find the total wall area (perimeter × height) plus the ceiling if covering it, add 10% for waste, and divide by the sheet size. A 14×12 ft room with 8 ft walls and a ceiling needs about 21 sheets of 4×8 drywall, costing roughly $880–$2,050 hung and finished.

Drywall sheet size guide
Larger sheets mean fewer seams to tape and finish, but are heavier to handle.
| Sheet size | Coverage | Best for |
|---|---|---|
| 4 × 8 ft | 32 ft² | Tight spaces, DIY |
| 4 × 10 ft | 40 ft² | Standard walls |
| 4 × 12 ft | 48 ft² | Long walls, fewer seams |
What affects drywall cost
- Project size — larger drywall jobs lower the cost per unit but raise the total.
- Material grade — premium products cost more but often last longer.
- Labor rates — local wages and demand swing installed prices significantly.
- Region — prices vary by state and metro (see local cost pages below).
- Site access & prep — removal of old material and difficult access add cost.
- Season — booking in the off-season can cut labor pricing.
