About

Lumber Calc publishes free lumber calculators for board feet, decks, stairs, and rafters. The Lumber Calc Editorial Team checks each formula against the cited building code or lumber rule before a page goes live.

The calculators cite 25 clauses from one registry. The full list is on the methodology page.

This page will name a human reviewer when that review is in place. Until then, the byline on tool pages stays with the editorial team and does not invent a person. The planning limits are on the disclaimer page.
