When did 2x4 stop being 2x4?

Size standards, maximum moisture content, and nomenclature were agreed upon only as recently as 1964. The nominal 2x4 thus became the actual 1½ x 3½, imperceptibly, a fraction of an inch at a time.

When was a 2x4 actually 2x4?

In general, homes built before World War II were likely to be built with rough-sawn full-dimension 2x4s. During the late 1940s or early 1950s, builders in many areas of North America switched to planed 2x4s that measure 1.5" x 3.5".

Why is 2x4 wood not 2x4?

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.

How did a 2x4 become 1.5x3 5?

The 2x4 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 2x4's from a given tree if they cut them slightly smaller to begin with.

When did the 2x4 change size?

Size standards, maximum moisture content, and nomenclature were agreed upon only as recently as 1964. The nominal 2x4 thus became the actual 1½ x 3½, imperceptibly, a fraction of an inch at a time. It was a 34 percent reduction in actual volume; as those in the trade would say, it's “selling air.”

Why is lumber not true to 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).

Why are 2x4 half an inch shorter?

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". The same is true of pine.

Is a 2x6 really 2x6?

2x Board Sizes

2x4 and 2x6 boards lose 1/2 inch in thickness and 1/2 inch in width before leaving the mill. That means a 2 x 4 board is actually 1-1/2 inches by 3-1/2 inches. The larger 2x boards (2x8, 2x10, etc.) lose 3/4 inch in width.

Why do 2x4s 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.
