What does 2×4 lumber mean?
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″.

Is a 4×4 actually 4×4?
But that doesn’t mean they actually mean the same thing. 4×4 and 4WD both mean that power is sent to four wheels to control the vehicle, but it’s a little more complex than that. All 4×4 vehicles have 4WD, but not all 4WD vehicles are 4x4s.
Is 4×4 really 4×4?
While it is true that the actual size of a 4 x 4 board is 3 ½ x 3 ½, that is not a deceptive practice in my opinion. It is well known that lumber is sold based on nominal sizes, and the actual size of the boards is smaller than the nominal size.

What kind of wood is used for 2×4?
Fir. Douglas fir is one of the most common woods used to make 2x4s. It is one of the cheapest types of softwood 2x4s. This makes it easy to screw into but still strong enough to be used for any project, including a house.
Why did 2×4 become smaller?
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.
