Mark-out

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.


Calculate Linear Boards from Deck Area
If your deck is an odd shape (circular etc) enter Total Deck Area and Board Width + Gap to Calculate Linear Boards.
Allow Waste % for joins and waste.

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 - there's dust in the spray mist too!
