If the shape of your deck is more complicated than a simple box shape break it down into boxes by adding additional sections. See an example.

Your HardieDeck Estimate is

To ensure you are ordering the right quantities we recommend you take this estimate, your deck dimensions and a few photographs of where your deck will be installed to your nearest HardieDeck stockist. The team there will be able to help you complete the purchase of your new deck which resists damage from rotting, warping and splintering.

Need edging?


Measure the perimeter to determine the length of edge capping required. Edge caps are used on the sides of the deck which are not butting against a building. See an example. They secure the perimeter boards in place and keep the fixings hidden. If you decide to not to use an edge cap, the edge boards will require face fixing.


Note this is not a calculation, just a record for your print out.

Pick an edge type:

  • Slimline Edge Cap

  • Fascia Edge Cap

  • HardieDeck™ Edging Board
