Deck Lumber & Fastener Calculators
Everything you buy that sits above the ground. These tools turn a deck size into a purchase list — board counts by stock length, fasteners by the box, and an honest comparison when composite is on the table.
A deck is bought in three passes: the boards you walk on, the lumber underneath them, and the fasteners that hold the two together. Getting the first one wrong is expensive and visible; getting the third one wrong means a trip back to the yard halfway through a Saturday.
Everything here works from actual board dimensions rather than nominal ones. A 5/4 deck board is 5½ inches wide, not 6, and that difference compounds across forty rows into three or four boards you did not buy.
Composite gets its own calculator rather than a footnote. It is a real option with real trade-offs, and the honest comparison against wood runs over twenty-five years — not over the first invoice.
