Why do they call deck boards 5 4?
There are several differences between these two wooden boards, however, the main difference is that they are different sizes. While they are both 5.5 inches wide, a 5/4 board is 1 inch thick, whereas a 2×6 board is 1.5 inches thick.
Why are wood sizes not the actual size?
Maybe you've noticed that lumber sizes are often misleading. The "nominal" cross-section dimensions of a piece of lumber, such as 2 X 4 or 1 X 6, are always somewhat larger than the actual, or dressed, dimensions. The reason is that dressed lumber has been surfaced or planed smooth on four sides (called S4S).
Can you buy actual size lumber?
All of our lumber is cut to true dimensions. Meaning if you order a 2"x 4" x 10' the piece of lumber you receive will be 2 inches thick, 4 inches wide and 10 feet long.

When did lumber dimensions change from actual to nominal?
Early concepts called for rough lumber to be of full nominal size, often in the dry condition. After World War I, the increasing demand for construction lumber led to the first national size standard in 1924. This was revised in 1926, 1928, 1939, and 1953, while still another revision is proposed for adoption in 1964.
Why isn't a 2x4 actually 2x4?
Now, most timber is milled and planed to give it a little more of a finished look, and a little more of a consistent size and profile. Because of this extra milling, a 2x4 no longer measures a full 2 inches by four inches. Instead, a 2x4 is really only 1 1/2" by 3 1/2".

What are the characteristics of individual pieces of lumber?
Individual pieces of lumber exhibit a wide range in quality and appearance with respect to knots, slope of grain, shakes and other natural characteristics. Therefore, they vary considerably in strength, utility and value.
What is stress rated lumber?
Machine stress-rated and machine-evaluated lumber is readily available for end-uses where high strength is critical, such as truss rafters, laminating stock, I-beams and web joints. Machine grading measures a characteristic such as stiffness or density that correlates with the structural properties of interest, such as bending strength. The result is a more precise understanding of the strength of each piece of lumber than is possible with visually graded lumber, which allows designers to use full-design strength and avoid overbuilding.
How thick is a 2x10?
