why is dimensional lumber not actually sold in the dimensions it is named (ie: a 2×4 is actually 1.5 x 3.5 inches)?
Lumber is rough cut to the actual dimensions. It is then planed to be smooth and to make it more consistent. They take off 1/4" from all sides for the smaller stuff like 2×4's and more as it gets bigger (like a 2×12).
