this gives you a total of 10 posts. if your deck geometry is different, you may have more or fewer posts. it is ideal to keep post span at 6 feet between posts, which is a standard length of railing sections. however, you can space them more frequently - for example at 4 or 5 feet apart.
to calculate the area, multiply the length of the deck by the width of the deck. be sure to account for any uneven areas, angled edges or other non-perpendicular spaces. if your deck is largely rectangular or square and then has a side piece, calculate those two areas separately and then add them together.
options and the materials grade, however, can push this total as high as $30 per square foot. if the new deck is not a diy project, standard labor figures for a deck that can be installed from the ground commonly run between $7.50 and $8.50 per square foot, but vary with the type of installers used and the region you live in.
before you even access how many screws you need, it's important to measure how large your deck is. to calculate the number of screws you need, you have to know the length and width of the entire deck. this will help you determine the square footage of the deck.
footage area of 12 to get 66. 66 is how many square inches are in a standard deck board. 3. dividing 144 square inches by 66 square inches is 2.1818. so 2.182 is how many standard deck boards 5.5 x 12' it takes to cover a square foot. we call this the square footage multiplier. example 2 similar 1. a square foot is 12' wide by 12' in length. determine square inches in a square foot by multiplying the width
once you have the square footage of the deck, you need to find the square footage of the board youve selected in feet. to find this multiply the width of the floor-board in feet times the length in feet. you can use our feet and inches calculator to convert the board width in inches to feet. to find the number of boards you need, divide the total deck square footage by the board square footage, eg. total ft 2 / board ft 2. deck estimating tips
