What is Drywall Calculator?
Drywall Calculator estimates how many drywall sheets you need for a room or wall project. Enter room dimensions and door/window openings, and get an accurate material count with waste factor included.
How to use
- Enter the wall dimensions — height and total wall length (perimeter for a full room, or individual wall widths).
- Subtract openings by entering the number and size of doors and windows in the room.
- Choose your drywall sheet size (4×8 or 4×12) and waste factor, then view the total sheets needed.
Result
A homeowner calculates drywall for a 12×14 ft room with 8 ft ceilings, 2 doors, and 1 window — needing 14 sheets of 4×8 drywall with 10% waste.
