How to Calculate the Amount of Deck Materials Needed (Construction Math) 2[(12W + d)/(x + d)][(12L + j)/j], and compute the number of screws needed for the frame of the deck with the formula. 4(12L +j)/j. Add the two numbers that you get, and this is the approximate number of screws you will need for the entire deck.You may want to factor in an extra 3%.ext, use the following equation to calculate the total length of deck boards needed to construct the top of the deck, L(12W-x)/(x + d) + L. You can use the simplified form, (12WL + dL)/(x + d). Add up the two numbers found in Steps 3 and 4, and this is the total length of board needed to construct the deck.

- When building deck stairs you will need to determine the total height of the deck at the stairs. This is the change in elevation from the top of the deck to where you expect the stairs to land. Place a level straight out from the deck and measure to the ground or landing using a tape measurer.You will also need to establish the tread depth and riser height for each step. The minimum tread depth is 10 and the maximum riser height is 8.In most cases this will be a 7-1/2 rise and 10-1/2 run. This will allow you to use two deck boards for each tread with a 1/2 reveal.Once you have determined the total stair height, tread depth, and riser height you can plug the numbers into the decks.com stair stringer calculator to find the stringer length, stair projection, and the angle of the stairs.lace a level straight out from the deck and measure to the ground or landing using a tape measurer.

- Calculating the Number of Capstones. To figure the number of capstones needed, dividing the length of the wall in feet by the length of the capstones in inches, then multiply by 12. For example, if the wall is 20 feet long and the capstones are 8 inches wide, then the number of capstones needed is [20/8](12) = 30.ultiply the wall's length by its height plus 1/2 a foot to find the total square footage of the wall. That is, calculate. Wall Area = L(H + 0.5) sq. ft, where L is the length of the wall in feet and H is the finished height of the wall in feet.

- You can then use the following basic formula: Linear feet x width = square footage/1,000 = MSF. Apply the formula to determine linear feet, which will be termed Y.. For example, say you have 250 MSF, and you know that the width of the material is 2 feet: Y x 2 = 250,000/1,000 = 250 MSF. Solve for Y by taking the square footage (250,000) and dividing by the width (2 feet), and you come up with the following. 125,000 x 2 = 250,000/1000 = 250 MSF. So 250 MSF of the material in this example converts to 125,000 linear feet when the width of the material is 2 feet.

How to Calculate Wood for a Deck Each rim joist is the length of one side of your deck. Make the width of each of the doubled-up rim joists, or outside joists, equal in inches to the length in feet the joist is crossing. For instance, if your deck is 8 feet, the rim joists should be constructed out of 2-inch by 8-inch lumber.
