So, if you’re planning a building project with “2 x 4”, make sure you measure everything out using the 1 1/2″ x 3/4″ measurement to get things right.
This “final” measurement is what is shipped and sold to suppliers, lumber yards and big box stores. “Actual dimensions” goes hand-in-hand with “nominal dimensions”, which is used to describe a piece of wood as it is first cut at the mill (rough cut) before getting planed and sanded down to its actual dimension. The nominal cross-section dimensions of a piece of lumber, such as 2 X 4 or 1 X 6. Of course, lengths are customized for each job.This is the term used to reference the exact dimensions of standard lumber and their measurements in inches. Learn about the nominal versus actual dimensions of lumber here.
The first dimensions are its nominal ones, the second measurements are its actual or. 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. The 4×4s are 3 x 3 and the 1×6s are of an inch thick and 5 wide. Standard widths are specified in the above publication, but can be customized as needed. The following table comes from the American Institute of Timber Construction's Standard Specification for Structural Glued Laminated Timber of Hardwood Species publication.ĪNSI/AITC A190.1-1992 allows for any width and depth of glue laminated timber. It is advisable to check with your contractor or lumber supplier before finalizing design details so you aren't surprised by what you receive. However, in some cases, like the big-box hardware stores, the boards come in dimensional widths similar to softwood widths.

Colors: White, Gray, Putty, Cedar, Tan, Black, Redwood, Chocolate Brown, Green, Weathered Wood, Anchor Gray, Harbor Wood. For instance, hardwood trim that ends up being just over 1" thick (surfaced on 2 sides) is called a five-quarter (5/4) board. Actual Size: 0.75' x 5.9375' (1.9cm x 15cm) Weight: 0.1.30lbs/ft. 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. Surfaced refers to a finishing process that smooths the lumber to remove all saw marks. If your project calls for precise measurements, be sure to check your lumber before purchasing. Hardwood lumber is sized based on how many sides are surfaced. Softwood lumber comes in a number of standard lengths as listed in the table below.

The planks are still planed to the same finished or actual dimensions, but more. Softwood lumber is generally used for framing walls and floors.
