Room dimensions
How does the calculation work?
Wall area is approximately the room perimeter multiplied by its height. For simplicity, the tool assumes a square room with the specified floor area. Window and door areas are subtracted from wall area, and the material allowance is added to estimated quantities.
Before you buy
- Check the actual dimensions and shape of the room.
- Check current prices, material usage, and delivery terms.
- Ask the contractor to clarify the scope and labor costs.
