Formula and assumptions
How this calculation works.
Count cladding stock from individually measured course runs and exclusions, with explicit end-joint and reuse assumptions. Cut demand per course = measured length − removed length + 2 × specified end trim; stock follows permitted pooling or continuous-piece packing.
A worked example
Illustrative inputs only. Product properties and design dimensions are not recommendations for your project.
- Selected stock board length
- 5 m
- Specified extra trim per course end
- 0 m
- Your permitted course joint plan
- One continuous piece per run
- Measured full course length
- 3 m
- Removed course length
- 0 m
- Identical courses
- 3
Cladding stock lengths for measured courses: 3 boards
Continuous-piece packing uses decreasing-length first fit. It is feasible for the stated pieces but is not guaranteed optimal. No cut kerf, damage or end trim is assumed; include these in your supplied piece lengths.
Before you purchase
Use dimensions from your plan and properties from your chosen product. Any design spacing, section or fixing pattern must already be specified.
All product dimensions, coverage, density, allowances and joining rules must come from your supplied plan or selected product. No building-code values are inserted.
