What is a Decking Calculator?

Our decking calculator is a free-to-use online tool that accurately estimates the amount of materials needed for a wide range of decking projects. Simply input the length and width of your decking space, the width of the board material you plan to use, and the spacing between each board. The calculator will then quickly determine the amount of material necessary to complete your build. It’s a highly convenient tool across all stages of a DIY decking project to ensure maximum efficiency of cost and planning time.

The Benefits of Using a Decking Calculator

A decking calculator comes with many benefits, such as accurate measurements, budget estimations, and reduced excess wastage. By determining an accurate amount of required decking material for your provided deck dimensions, you can create a realistic budget suited for your needs without overspending. This also reduces the environmental impact of your project by minimising material wastage going into landfill, as well as helping you avoid excessive inconvenient trips back to the shops.

DIY Project Planning with a Decking Calculator

Planning a DIY decking project involves several stages of construction, and Canterbury Timber’s decking calculator can assist you throughout the whole process.

The first step is crucial for understanding the scope of your project and setting a realistic budget. The decking calculator helps you with this by providing an initial estimate on the materials required. You can then compare the amount of different materials needed based on the width of the board types you input and compare what options fit your budget range.

Once you have your initial calculations, you can refine your measurements based on a desired aesthetic by considering deck shape, patterns, and additional features like railings or built-in seating for your project. We also offer cutting and milling services to fit your new timber for any desired deck shape and aesthetic, plus same-day delivery in the Sydney Metro area.
