Common Methods for Pricing Lumber Lumber is usually sold in one of two ways: by the lineal inch, or by some method based on the square foot dimensions of the lumber being sold. Of the two, the "lineal inch" method of pricing lumber is the simplest and most familiar. Lumber sold by the lineal inch is cut to a specific width before it is offered for sale. The price is determined by the length of the material being purchased. A 12'' long hardwood board priced at $.10/in. in. costs $1.20.

"Random-width lumber" is lumber that's not cut to a specific width before it is sold. As the name implies, the width of boards sold as random-width lumber varies. Woodworkers who buy random-width lumber cut the lumber to width themselves, and understand that some amount of waste will be generated in the process. A pricing system for random-width lumber has to take the varying widths of the boards being sold into account. The most common method of pricing random-width lumber is by the "board foot." Board feet are calculated by multiplying the surface area of the lumber (measured in square feet) by the thickness of the lumber (measured in inches). Examples: A board that's 1'' thick, 12'' wide and 24'' long is: (1 foot wide) x (2 feet long) x (1 inch thick) = 2 board feet of lumber. A board that's 2'' thick, 12'' wide and 24'' long is: (1 foot wide) x (2 feet long) x (2 inches thick) = 4 board feet of lumber.
