What are standard 2x4 lengths?
Hereof, how long is a standard 2x4?
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. A 1x6, for example, actually measures 3/4" x 5 1/2".
Subsequently, question is, how long is an 8 foot 2x4? Specifications
|Common Measurement (T x W)||2-in x 4-in|
|Common Length in Feet||8-ft|
|Common Length in Inches||96-in|

Why is a 2x4 actually 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.
