Formula and assumptions
How this calculation works.
Positions on each axis = floor((bed dimension − 2 × supplied margin)/supplied spacing) + 1; multiply axes and identical beds.
A worked example
Illustrative inputs only. Product properties and design dimensions are not recommendations for your project.
- Your supplied row spacing
- 1 m
- Your supplied spacing along rows
- 1 m
- Your supplied margin at each row-axis edge
- 0.5 m
- Your supplied margin at each column-axis edge
- 0.5 m
- Measured bed width across rows
- 3 m
- Measured bed length along rows
- 4 m
- Identical beds
- 1
Supplied grid positions: 12 positions
A position is placed at each starting margin, then at every supplied spacing. Boundaries are inclusive; species and appropriate spacing are not selected.
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.
