Board Foot Calculator

Board Foot Calculator is a free online tool designed to help users tally lumber quantities and estimate costs using the board foot measurement standard. It enables individuals to build a lumber tally by adding each board, selecting a thickness from 4/4 to 16/4 or entering custom dimensions in inches, and then automatically calculates the total board feet and estimated cost. The tool applies the standard formula for board feet, multiplying thickness (inches) by width (inches) by length (feet) and dividing by 12, using nominal dimensions as referenced in the USDA Forest Products Laboratory's Wood Handbook.

This calculator is particularly useful for those working with hardwood lumber in North America, where the board foot is the standard unit for pricing rough lumber. Users can specify board thickness, width, length, quantity, species, and price per board foot, making it practical for sawmills, hardwood dealers, lumber yards, and anyone needing to plan or estimate lumber for a project. The interactive tally feature allows users to add multiple boards and see a running total of board feet and estimated costs.

Board Foot Calculator is web-based and does not require sign-up to use. It offers additional conveniences such as a printable cut list and the ability to copy the tally as text. The tool also provides quick reference answers for common dimensional lumber sizes, and includes a printable chart for board foot calculations. It is available without charge and is accessible directly through a web browser.
