Even board spacing
Fit a fixed number of boards into a span with equal internal gaps.
How this works
Internal gap = (span − board count × board width − two edge gaps)/(board count − 1).
Example
Using the example inputs, gap between adjacent boards is 100 mm.
- Clear span
- 2 m
- Board face width
- 0.1 m
- Board count
- 10
- Gap at each outside edge
- 0.05 m
- Gap between adjacent boards
- 100 mm
