a porch is not a deck |
Tolbert's unsuitability to answer the question at hand is made clear in her first sentence:
"The amount of wood you will need for a 12-by-12-foot porch is determined by your deck plans and your experience as a carpenter."
"You will need a 2-by-10-inch ledger board if you are attaching the deck to the house. Posts are usually constructed from 4-by-4-inch or 6-by-6-inch posts and you will need at least five. You will need 18 boards of 2-by-6-inch lumber or nine 2-by-10 inch boards to build the joists, also known as the beams. You should purchase an additional 25 percent wood [sic] to allow for framing pieces and waste."Ummm, no, Jennifer, that's a deck. And what's this bushwa about "18 boards of 2-by-6-inch lumber or nine 2-by-10 inch boards"? Where on earth did you get that rubbish? You need the same number of joists regardless of the width of the 2-by lumber.
Once Tolbert finally gets to the question the OQ most likely wanted answered, she botches it completely:
"A 12 -by-12-foot deck will need 144 lineal feet of decking."Only if the decking is one foot wide, Jennifer. The linear footage you actually need must be calculated with the following formula:
In other words, if your decking is four inches wide, you need 432 linear feet of decking. If the decking is six inches wide, you need 288 linear feet.
Tolbert closes with the rather bizarre statement that,
"You may also choose to add three 1-by-12 inch boards as a skirt board."Ummm, Jennifer? 1) a porch doesn't have a skirt; 2) if they did have skirts, you'd want to specify a length; and 3) what if your porch is more than 11¼ inches above the ground?
