Decks built today must comply with the National Construction Code (NCC), which outlines the current regulations for all new construction work in Australia. Most professional builders would know exactly how much decking you’ll need for your property to comply with these codes.
However, this is one of the most frequently asked questions by anyone considering a certain decking style and doing it themselves. You’ll need to create your own decking calculator and calculate the surface area of your future decking in square metres.
It is the foundation for all of your future decking costs. The timber decking installation prices are estimated based on the surface that has to be installed.
Tile Importer provides information on how to calculate lineal metres as well as a fair estimate for square or rectangular decks with a straight board plan.
How to Calculate How Much Decking You Will Need
Step 1: Calculate the size of your deck
The first step is to calculate the square metres of your deck area by multiplying its length by its width (L x W). If your deck has multiple platforms of varied sizes, simply add up the area of each platform to get the overall area.
If the area isn’t a simple rectangle or square, split it into several rectangles or squares, taking the length and width of each section.
Step 2: Decide on the board length to use
If you’re planning on building a large deck, it may be tempting to go for the longest boards during construction, but the longest board isn’t necessarily the best fit. It might be wiser to go for shorter board lengths to get a tighter, more durable fit.
When in doubt, Tile Importer’s knowledgeable staff can easily help you identify the board length you need for your project.
Step 3: Determine board square metre
After you’ve decided on the board length, the next step is to compute the board’s square metre. To do this, multiply the board’s length by the width to figure out how many square metres you need to cover. If you have multiple areas, combine them later.
Step 4: Get the number of deck boards
Take the area of your deck and divide it by the board area to get the number of deck boards you’ll need for your project.
Step 5: Determine your board spacing
It’s important to consider your board spacing when calculating how much decking you’ll need. This might seem like an insignificant thing, but the slightest mistake here can make or break your project. Some factors to consider when calculating for board spacing include the expansion and contraction of the type of wood you chose, water drainage and ease of clean-up.
Step 6: Cover for waste, mistakes, and off cuts
It’s a good idea to buy a few additional boards than you think you’ll need. To be safe, add a 10% to 15% scrap rate to the number of boards you’ll need to compensate for mistakes, off cuts, and waste. For example, if you have eight deck boards, you should purchase 10 to 12 boards in total.
How Do You Work Out Linear Metres?
You’ll need linear metres because that’s how you’ll most likely buy your decking timber.
Decking boards should be spaced around 3 mm apart as a general guideline. As mentioned, you should also put in a 10 percent waste rate.
Divide your square metres by the width of one decking board plus the 3 mm gap to get linear metres. We recommend consulting with the supplier, but generally these boards come in 64mm, 86mm, 130mm, and 135mm widths.
These calculations may seem intimidating to a beginner DIY-er, but would be useful for those willing to take on big projects. However, we highly recommend you seek out the help of a professional builder to not only ensure that you get accurate measurements, but that you also comply with safety codes.
