Deck boards calculator

Linear feet and board count for a deck surface.

How it is worked out

area ÷ (board width + gap) = linear feet, plus waste

What it assumes

A 5/4 × 6 deck board is 5.5 in wide; a quarter-inch gap drains and moves.
10% waste covers end cuts and the bad boards in the lift.

Nothing on this page is a demo of the real thing — it runs the identical code. What a TradeForge account adds is everywhere the number then goes: saved against the job it belongs to, dropped straight onto a quote, and priced at a rate built from your own overhead instead of a guess.
