I dont know why they have to lie about it. At $5/8ft board you’d think I paid for the full 1.5. Edit: I mixed up nominal with actual.

No its not Maybe in the US? At least here, it is and has to be, very precise especially when it comes to industry quality. It is precise down to the mm!
Yeah but they measure in feet and cheesburgers.
And lies, don’t forget the lies
Alternative facts, thank you very much
In bullshit, which is itself an imprecise metric.
How does that work when wood varies due to moisture content? If they give precise mm measurements, only 20% of boards will meet those criteria.
All they are giving is the planned dimensions instead of nominal in mm form, it’s still not precise, it can’t be.
Maybe they mill, store, and sell under the same moisture conditions?
Also, how big is the difference in size and moisture for the same piece of wood? I would expect that moisture is usually not higher than 90% and not lower than 10% or something like that, but don’t know how it really is
Once it leaves the mill they go to various stores and regions with different conditions. Some places store them inside, others outside.
Once I buy it at the store and take it the site, it’s now different from the store. You should acclimate all lumber for 48 hours before using it as well, this is so the wood doesn’t swell or shrink more after installing it.
A 2x10 can be anywhere from 9-1/2 to almost 8-1/2 depending on final site conditions.
So, more than 10% difference, that’s enough to be a problem, indeed
Bullshit. Wood expands and contracts so ther is no way you can be precious down to the mm.
That’s why the standards specify the moisture content of the wood as well as the dimensions. This is even the case for US standards.
I’ve not really encountered this wood expanding and contracting thing. Are you sure?
You aren’t serious are you…?
Exaggeration
Realistic answer
Boards can shrink and grow due to moisture.
True, but the amount they shrink and grow across the grain tends to be proportional. A 2x4 is very rarely measurably different from 1.5"x3.5", but a 2x10 (like you’ve shown) is 1.5"x9 1/4" but is often anywhere between 9 1/8" to 9 3/8"
That’s crazy, how can you make a profit if you give the customer the exact measurement? You have to saw a bit off and pad your earnings!
That’s not why there’s a nominal size vs actual size.
