Formula and methodology
Formula: Boards = ceil(wall length/board width × (1+waste)); battens = floor(wall length/spacing)+1; wall area = length × height.
The estimate treats the wall as a rectangle and counts full-width boards plus regularly spaced vertical battens.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Wall length — length units; minimum 1.0E-6; maximum 1000000
- Wall height — length units; minimum 1.0E-6; maximum 1000000
- Board face width — length units; minimum 1.0E-6; maximum 1000000
- Batten center spacing — length units; minimum 1.0E-6; maximum 1000000
- Waste allowance — %; minimum 0; maximum 1000
Worked example
| Input | Value |
|---|---|
| Wall length | 6 |
| Wall height | 2.5 |
| Board face width | 0.2 |
| Batten center spacing | 0.4 |
| Waste allowance | 10 |
Wall area = 15; boards ≈ 33; battens = 16.
Assumptions and limits
- Boards and spacing use the same length unit; every board spans the wall height.
- Waste is applied to the board count only and counts are rounded up.
- Openings, corners, trim, starter pieces, fastening, local practice, and structural requirements are not modeled.
