A piece of surfaced (sanded smooth) 2×4 lumber actually measures 1½ inches thick and 3½ inches wide. In rough-cut condition, a 2×4 is slightly less than 2 inches thick and approximately 4 inches wide. When wood is milled from a rough to a smooth surface, it loses about ¼-inch from each of its four sides.
What is a 2×4 actual dimension?
The true measurement of a 2×4 is actually about 1.5×3. 5. When the board is first rough sawn from the log, it is a true 2×4, but the drying process and planning of the board reduce it to the finished 1.5×3. 5 size.
Why is a 2×4 only 1.5×3 5?
The 2×4 refers to the rough-cut green wood: it shrinks during drying, then the dried wood is planed smooth, so the finished lumber is supposed to end up at 1.5″x3. 5″. While it doesn’t really shrink that much, the mills get more usable finished 2×4’s from a given tree if they cut them slightly smaller to begin with.
Is a 2×4 actually 2×4?
DIMENSIONAL LUMBER: In the past, when a timber was called a 2×4 [or “two-by-four”], it actually measured 2 inches by 4 inches. Because of this extra milling, a 2×4 no longer measures a full 2 inches by four inches. Instead, a 2×4 is really only 1 1/2″ by 3 1/2″.

What do they call a 2×4 in Europe?
I cant speak for the hole of europe, but at least in Norway a “2×4″ is 48×98 mm. If you go to a lumberyard, you buy 48×98 as everything is measured in metric, but in the daily speach most people still use the term 2×4, 2×8 aso. The Inch measurement is in use as long as we speak about size on TV(40″) and cartyres (15”).
When did they stop making real 2×4?
This pressured further compromise because thinner 2x4s were a way to compete in price with wood alternatives. Size standards, maximum moisture content, and nomenclature were agreed upon only as recently as 1964. The nominal 2×4 thus became the actual 1½ x 3½, imperceptibly, a fraction of an inch at a time.
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 are wood dimensions wrong?
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). The nominal measurement is made before the lumber is surfaced.
Is a 2x4x8 actually 8 feet long?
2×4 – 8′ Lengths Although not quite as common as the pre-cut studs I described above, my local Home Depot has a fairly good selection of 2x4s that measure 8 feet (96”).
Are 2x4s smaller now?
The simple reason why 2×4 is not 2 inches by 4 inches is that lumber mills trim off rough or warped surfaces of a 2×4 to give it a more polished and finished look. By planning the lumber on all four sides, the original 2×4 is now reduced to 1 ½ inches by 3 1/2 inches.
What is a 2 by 4 in the UK?
I know from reading around that size wise this would roughly equate to the UK’s 44 x 96 and 25 x 44 but it is my belief that in the US if someone refers to ‘Using a bit of 2 x 4’ then more is understood than just the size. It is also known what the type of wood it is, the cut, whether it is sawn / planned and so on.
How wide is a 4 by 4?

What do they call a 2×4 in Canada?
In Canada, where we adopted the metric system in the early 80s, we call them 2x4s.
What does it mean if someone calls you 2×4?
A two by four is a common format for a piece of wood: A length of sawn wood of cross section 2 inches by 4 inches, most often employed as structural framing lumber (dimension or dimensional lumber). “It hit me like a two-by-four” means that you’ve been hit pretty hard.
How far apart are studs in Europe?
