Formula and assumptions
How this calculation works.
Fit identical whole-pane film blanks in a roll, preserving trim allowance and permitted film orientation. Blanks per roll = floor(roll width / blank width) × floor(roll length / blank height); rolls = ceil(panes / blanks per roll).
A worked example
Illustrative inputs only. Product properties and design dimensions are not recommendations for your project.
- Measured pane width
- 0.5 m
- Measured pane height
- 2 m
- Specified trim allowance at each edge
- 0 m
- Identical panes
- 10
- Roll width
- 1 m
- Roll length
- 5 m
- Product orientation restriction
- Fixed orientation
Film rolls for whole-pane blanks: 3 rolls
Identical panes, straight lanes and one common orientation. Continuous roll length is not pooled across separate rolls: the engine checks physical row fit. Product suitability, glass compatibility and directional restrictions must be confirmed separately.
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.
