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. 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.
What size is 2×4 wood?
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.
Why is it called a 2 by 4?
The ubiquitous lumber product known as the 2×4 does not, in fact, measure two inches thick by four inches wide. The naming of this building material is the result of compromise between forestry technology, species’ properties, forest composition, transportation efficiency, construction speed, and price competition.
What is the actual size of a 2 by 4?
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.
What does 2x4x8 mean?
The 2 tells us the thickness of the board in inches, the 4 is the width of the board in inches and the 8 is the length of the board in feet.

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.
Is lumber a timber?

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.
Why do 2×4’s have rounded edges?
2×4 have rounded edges as it’s very beneficial to the wood itself and those working with it. They reduce the number of injuries like unwanted splinters during the handling and manufacturing process and also ensure that the lumber stays looking its best all throughout until the customer sees it.
Can you paint pressure treated wood?
Yes! You can paint pressure-treated wood. But, if the lumber has been chemically treated with chromate copper arsenate (CCA), surface-treat it before applying paint. Use oil-based acrylic instead of water-based paints or stains because the chemicals in the treated lumber are sensitive to water-based paints.
What length do 2×10 come in?
Floor Joists Floor framing requires 2-by-8, 2-by-10 or larger dimensional lumber. Normally, these are available in 8- to 16-foot stock lengths.
