Why are 2x4s 1.5x3.5?
Answers:
The lumber does not shrink unless you are using a soft wood (birch ceder.... Ext. ) It goes more along the lines of the industery changing and the bottom plate of a wall is not true 2x4 it is the same ase the studs in the wall just laied flat..... Unless you order true numbers with lumber you get 1 1/2 x 3 1/2

they are just rounding up...
Ummmm lemme see...
the answer is: potatoes.
aw god dam it i cant think at the moment.. really... high.. and drunk.. very drunk
just accept what you can't change and stop worrying
The base piece of wood is 2" x 4". In order to give you nice smooth pieces, they plane off about a quarter inch from each side.
Old rough lumber is actually 2x4.
because the rate of shrinkage is not consistant nor is it predictable. At least this way we have a nice upper bound so that stuff will fit together.
You have to understand that they r trying to save money ansd make money at the same time so of course there not going to use extra material.
2x4's used to be actually 2x4. industry standards changed, but the name of the board didn't.
Way more sense. But the lumber industry set this standard years ago, maybe as a cost thing. More boards per tree. In older houses, the lumber is actual size. True 2x4"s and floor joists 2x12"s
Pressure treatment doesn't make boards shrink--besides, not all lumber is pressure treated. In fact, not all lumber is even dried. You can buy green 2X4s. If you buy a "rough" 2X4, or a hardwood 2X4, it will really be 2" by 4". The reduction comes from the finishing (smoothing, rounding the edges, etc...) to make the board useful for modern construction. For example, many older homes will have a redwood board on top of the foundation. This will be a rough cut board, and it will measure 2" X 4" exactly, but the studs attached to it will be of finished lumber and will have the smaller dimensions that your are asking about.
They are cut 2x4 and then planned down to 4.5x2.5. When they are dried then they shrink.
they are cut 2x4 but have to be planed down and end up being 1.5x3.5
It's a man-thing; you wouldn't understand! Just kidding, but truly, if a woman had developed this "system" you'd end up with a two inch by four inch 2"x4" and something quite nice made with the leftovers created when she milled the larger pieces down to size.
LOL, smile guys, I'm just kidding. Hey just be glad I didn't bring up the issue of the 'dummy end' of the measuring tape!
It's an approximation of size...nothing in lumber is exact.
