Estimating lumber - Estimating decking Materials. • for a small deck, 10 × 12 feet, for example, determine how much lumber you'll need by using your detailed plans to count all the pieces of each size: 12-foot 2 × 4s, 8-foot 2 × 6s, and so on for all framing members, including stairs and railings. Add 10 percent to framing and 15 percent to decking to allow for waste. • Calculate the decking required based on the actual width of the boards you will use, including the gap between boards.

29 Mar 2010 Divide the total square feet by the number of square feet per board. The typical 5/4-inch-by-6-inch treated deck board, 8 feet long, will cover 4 square feet of deck. Divide 225 by 4, which equals 56 with a one-square-foot remainder. Round up to the nearest whole board. for the example, you would need 57 boards.
5 Apr 2016 Next, we want to figure out how many decking boards we need. There are two ways that we can do this. One way is to find the total square feet (length times width) of the deck and the square feet of a single decking board and then divide it out. To better explain our example we will figure it out the other way. Our joists will come 12 feet out from the house and the decking will run the 16 feet width of the deck (parallel with the house). We want our decking boards to
