How much decking do I need?

It’s not always easy to work out your decking requirements. So we’ve put together a simple-to-use composite decking calculator, which estimates how many boards and fixings you’ll need.

Please remember that our Essentials, Heritage and Signature collections are screw-fixed, whilst Evolution is a clip-fixed system.

How the decking calculator works

It’s really simple! First, select your decking collection from the drop-down menu.

Then input the desired length and width of your deck.

The calculator then works out your deck size, as well as the approximate number of composite decking boards and screws/clips required.

Don’t forget….

We advise you to add 5% wastage to the amount shown, to be extra sure that you’ll have enough materials to finish the job!

Don’t forget – the figures shown are only an estimate. For more accurate quantities and to get a quote, please get in touch with our friendly team of experts.
