If you want to build a deck, you might want to know the number of deckings that will be enough for your project. Knowing the amount of decking you need to complete your deck will also help you understand how much to budget. If you don’t learn how to calculate how many decking boards you will need, read this article to know how.
Calculating Your Decking Boards
You can use a calculator to calculate the number of decking boards in building a deck. Using a calculator to estimate the number of decking boards you will use is the easiest method. It is much easier than doing the calculation by hand.
The first step to take if you want to calculate the number of composite or wood decking boards for making your deck is to determine your deck size. How large do you want your deck to be? Do you want it small or big? Estimate the dimensions of your deck to know its size.
You can use a tape measure to determine its dimension. Use the tape to measure how long you want your deck. You also have to measure how wide you want it. After you have gotten its length and its width, multiply both together to determine the deck area.
Next, you also need to know the lengths of the decking board you want to use. Most wood and composite decking boards have different board lengths that range from 6, 8, 10, 12, and 16 feet. The widths are also 3½ inches or 5½ inches. Once you get the board length you want, choose your joist spacing. Most joist spacings are 12 and 16 inches in the centre, depending on whether your deck is for residential or commercial use.
If your deck is for residential use, choose a joist spacing of 16 inches in the centre. But for commercial use, choose a spacing of 12 inches in the centre. You can always check on your locality building code to determine adequate spacing for your decking.
Steps to Calculate How Many Deck Boards You Need
You can calculate the number of decking boards you need for your deck project in three simple steps. You will need a jotter, pen and a calculator.
Step One: Estimate the Deck Area
Start by calculating the total area of your deck. You can make use of a calculator to make the calculation easier. Multiply the length and the width of your composite decking to find your deck area.
Step Two: Calculate the Board Area
Knowing the total area of your deck, proceed to find the total area of the decking board you want to use. Calculating the area of your composite decking is easy. You have to multiply the board length together with its width in feet.
For instance, if the length of your decking board is 16 feet, and the width is 5½ inches, first convert 5½ to feet by dividing it by 12. You can as well use a foot-inch converter to change your board’s width to inches. Convert the board’s width to inches and multiply the result with the length of the decking. The final result is your board area.
Step Three: Calculate Boards
You can now calculate how many decking boards you will need since you have your deck and board area. To find the number of decking boards you need, divide the total deck area by the board. Your result is the number of decking you will need to complete your decking project. However, it’s advisable to purchase extra decking boards to account for waste. In addition to that, it is also good to purchase extra fasteners for your decking.
