There are many ways to stagger board joins - randomly or in a pattern.
This calculator spaces board joins with a 3 or 4 butt pattern (3 or 4 boards between joins per joist)
Drag Adjust Start and Adjust Board to spread the joins and see how the patterns look over the entire deck.
This is intended as a visual representation of options only, and may effect offcut re-use and increase waste!
DO NOT pre-cut boards.
Measure and cut to fit joist centers.
Allow extra board overhang (Joist Set in) and trim deck edge after installation.
Drag Adjust Start and Adjust Board sliders to see how the join patterns look over the entire deck.
Enter Costs per Linear Foot and % waste to calculate Total Cost and Material List
Enter cost per linear metre and wastage % for Stumps, Bearers, Joists and Boards to Calculate individual and Total Costs.
Linear metres and cost are auto updated when the deck is re-calculated, with individual costs for stumps, bearers and joists displayed in each section.
Hit + and - buttons to open or close spacing, re-calculating the deck to find how different spacing options effect cost and materials.
If your deck is slightly out of square (different widths each end), calculate board spacing results for both widths, and set out each end to suit.
Hopefully the slight difference in board gaps at each end of deck is acceptable, compared to equal gaps and cutting the last board at an angle.
