Dimensional lumber is cut to a specific length, width, and depth. However, there is a difference between the nominal size what the lumber is referred to and the actual size. The tables below provide both the nominal and actual lumber dimensions for many common North American lumber sizes. Softwood lumber is generally used for framing walls and floors. Softwood lumber comes in a number of standard lengths as listed in the table below. According to NIST Publication P20 , actual lengths must be at least equal to the nominal length, but can be up to 3" longer than the nominal length. Hardwood lumber is sized based on how many sides are surfaced. Surfaced refers to a finishing process that smooths the lumber to remove all saw marks. In North America, hardwood lumber is usually specified using the quarter system, where a board is identified by its thickness in quarters of an inch. Hardwood board widths vary. In most cases, hardwood boards come in random widths to be ripped to size by the woodworker. However, in some cases, like the big-box hardware stores, the boards come in dimensional widths similar to softwood widths. It is advisable to check with your contractor or lumber supplier before finalizing design details so you aren't surprised by what you receive. Standard widths are specified in the above publication, but can be customized as needed. A wide range of depths are available, far too many to list here, so please contact your local manufacturer for more information on their offerings - in general depths start at 6" and go up to 30" and beyond.
