of the decking face, plus the height of the joist. In either case, the ledger should also be flashed with metal to prevent water from seeping between the ledger and house.
This calculator is intented as a guide. Even though we have based the calculations on the IRC, you must always check with local building codes to ensure there are no variances.
Use the above Deck Calculator to calculate the square footage of your deck into linear footage of tongue and groove decking material. For more on lumber sizing be sure visit our lumber sizes page. Board Footage Calculator. Use this calculator to find out many board feet a piece of lumber is based on its thickness, width, and length.
Measure from the corner stake along one angle of your corner to 3 feet. Measure from the post along the opposite angle to 4 feet. Mark both points and measure between them diagonally.
To cut the beams to the right length, start by setting the end of a straight joist against the house at the edge of the deck layout. Square it by marking the house 6 feet from the deck corner and marking the joist 8 feet from the corner.
Lumber Sizes and Measurement Framing lumber is identified by the height and width of the board. The measurements used, however, may make you think you are getting cheated
To use a string to mark the curve on your joist ends first measure the width of the curve you intend to create, from one end to the other. At the edge of the deck, where your curve will be, mark the center of the curves width.
Measure out how much total rise your stairs need. Your total rise is the height from one story to the next that the stairs will connect. The total rise should be set in most cases, so you simply need to measure the height.
Five basic components make up any deck: decking, joists and when attached to a house, a ledger , beams, posts, and footings. To ensure that a deck is safe and strong, local building departments have strict code requirements for these components.
This guide will offer some basic instructions on how to build a generic 12x20-foot deck, including the preliminary elements with a foundation of concrete piers, and steel reinforcement set in soil, using 2x8 joists and 2x6 decking.
Set a long level on top of the decking and measure the height at the point where you want your steps to end. Use this measurement to determine the number and height of the risers. For example, if the height is 55 inches, divide this measurement by 7, the ideal height in inches for each step.
If we then compare that 2x8 layout with our base case 2x10s at 24-inch centers , we find that although the smaller joists are cheaper, we would need more of them because of the tighter spacing, so the material cost would increase 17%, and labor would be 44% higher.
Install the front trim board, flush with the deck top, over your faceplate, using the same techniques. Decking boards cannot be bent to follow curves in the edge of the frame.
