how much wood is required to make 1x 2by4,
fohat.digs:
In the old days, saw mills cut logs into "rough" lumber, wherein a "2x4" board was actually 2" tall and 4" wide and not very pretty. Later on, after it had dried out a bit (and usually done a bit of twisting) during transport and storage at the lumber yard, many customers wanted it "dressed" so about 1/4" was planed off of each face to make them clean and smooth. Thus the nominal "2x4" was whittled down to an actual 1-1/2" by 3-1/2" that we see today.
Larger timbers lost even more, today a "2x10" is only 9-1/4" wide. And since "1x" lumber is thinner they only planed off 1/8" from each side and actual thickness is 3/4"
Obviously, that was back in the old days. Today lumber is only cut once so those nominal sizes really just give sawmills a bonus.
Generally in the US if you request "rough cut" lumber you do get the full size, but that is uncommon in general building projects. It is more common in specialty construction such as outdoor pergolas or fences.

Correct. We get full sized logs, bark on and slash them into 8 foot logs then run them through debarking machines. The logs are then sorted by thickness and run through a couple of 2 story tall band saws to turn them into cants which are just logs with the sides cut off.
They are then scanned through some lasers which tell the next sets of saws how many pieces of lumber are in the log and where to cut. Larger logs will have a bit of everything from 1x3 up to a 2x6. The boards are then scanned again, trimmed to length and sorted by dimension. They are then stacked, steam kiln dried and run through our planing mill to dress them as you mentioned. We process around 200,000 FBM every 8 hours.
Everything else gets chipped and used for our attached paper mill.
Our bark and sawdust is then burned at the boiler house to power the paper mill and heat all the buildings in the winter. So very little waste.

That is a narrow range. Do you ever do larger boards (~2x12) or large timbers like 4x12?
