Woodworking and lumber guides
Learn how to measure lumber and use the tools with worked calculations, size comparisons, and dimensioned diagrams. Start with board-foot quantities or check which lumber dimensions your task needs.

How to calculate board feet
Turn board measurements into a lumber total you can check. Learn which dimensions to enter, how to combine different sizes, and how to allow for milling without counting the same material twice.
-
Nominal vs. actual lumber dimensions
Use a lumber label to identify the product, then choose the dimensions your calculation needs. Compare common dry surfaced softwood sizes and follow examples that separate physical volume, trade tally and whole-board purchasing.
