Estimate for planning, from what you entered and the product data shown. Check product labels and your supplier before you buy.

Each figure is thickness times width times length in inches, over the cubic inches in a board foot, with the size as named. A dressed board is smaller than its name, so a count by actual size is lower.

What a board foot is

A standard measure of wood volume. One board foot is 144 cubic inches, equal to a board one inch thick, 12 inches wide, and 12 inches long.

Virginia Department of Forestry, Board Foot (glossary) (web page, no date shown)[1]

Ten 2x4 boards eight feet long are 53.33 board feet by that rule. The calculator adds a waste allowance to the total and rounds the boards and the board feet up once.
