## About

Lumber Calc publishes free lumber calculators for board feet, log scale, stairs, deck boards, balusters, and rafters. Built for DIYers and pros, each page shows a diagram, a code check, and a shopping list.

The tools run in the browser, so numbers typed in stay on the device. Code checks reference IRC and DCA 6 and appear next to each result. Lengths stay exact to 1/16 inch until the final display.

## Use cases

- Calculate board feet and log scale for lumber purchases
- Plan deck boards, stairs, and baluster spacing
- Size rafters and check roof pitch
- Generate a printable shopping list for a project
