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 2×4 no longer measures a full 2 inches by four inches. … A 1×6, for example, actually measures 3/4″ x 5 1/2″.

Why is lumber cut smaller?

The real reason is the lumber mills decided some decades ago to cut green wood smaller – getting more boards out of a log. The shrinkage continues even now as you’ll notice all lumber sizes are shrinking even with the “reason” that was sold to the public as to why the boards are not full measurements.

When did lumber sizes change?

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.

Through the drying process, the boards naturally shrink, as moisture leaves the beams. Without the rough edges, what went in as a 2-by-4 planks of rough-sawn wood is now a tongue-tripping 1.5-by-3.5, having lost approximately ¼-inch on all sides to the planer and drying processes.

When did a 2×4 get smaller?

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. It was a 34 percent reduction in actual volume; as those in the trade would say, it’s “selling air.”

I cant speak for the hole of europe, but at least in Norway a “2×4″ is 48×98 mm.

The Inch measurement is in use as long as we speak about size on TV(40″) and cartyres (15”).

Why are 2×4 edges rounded?

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.

Why do they make 92 5/8 studs?

To create a wall that will match up with a typical 4×8 sheet of drywall, the studs need to be a little shorter — 92 5/8” to be exact. This also allows a little extra room along the bottom of the wall for variances in flooring and to keep the drywall from soaking up moisture from the floor.
