Estimate drywall sheets, basic supplies, and total cost for your room.
This calculator helps you estimate drywall sheet count, surface area, supply cost, and a rough project total for walls and ceilings.
Suppose you are finishing a 12 by 12 room with an 8 foot ceiling, one door, and one window using standard drywall.
That kind of room often lands in the high-teens for sheet count once walls and ceiling are combined, which is why drywall projects can grow quickly in cost once finishing supplies and labor are included.
| Type | Cost per Sheet | Thickness | Pros | Best For |
|---|---|---|---|---|
| Standard | $15 | 1/2 in | Common and affordable | General interior spaces |
| Moisture Resistant | $20 | 1/2 in | Better for damp areas | Bathrooms, basements, utility rooms |
| Fire Resistant | $24 | 5/8 in | Added fire resistance | Garages and code-driven assemblies |
Small repairs can be DIY-friendly, but full rooms and ceilings often become more demanding when finish quality matters.
A small room with standard ceiling height often needs around 17 to 20 sheets once you account for walls and ceiling.
4x8 sheets are easiest to handle. Longer sheets reduce seams, but they are harder to move and install.
Basic drywall hanging can be DIY-friendly, but finishing work often takes more skill and patience.
