Enter cost per linear foot and wastage % for Stumps, Bearers, Joists and Boards to Calculate individual and Total Costs. Linear feet 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.

Out of Square If your deck is slightly out of square (different widths), calculate results for both widths, and set out each end to suit. If necessary, adjust number of deck boards to match in both calculations, and see if different board gaps at each end of deck are acceptable, compared to equal gaps and cutting the last board at an angle. Use the widest dimensions for linear quantities.





DON'T BREATH THE DUST If you're cutting blocks, concrete, stone or ANYTHING and there's DUST - DON'T TAKE THE RISK
Don't cut it, or cut it wet so there's NO DUST - Silicosis Sucks
And if you're cutting wet, wear a mask - theres dust in the spray too!

How should we spell it?
