I think this is an interesting question but I'm struggling with how to make it fit the SE format, other than to ask for a reference that lists common dimensional lumber sizes in various countries. Does anyone have other ideas?

Lumber size standards outside the US?

I guess the question I was really trying to ask was whether the metric universe had standardized a set of common off-the-shelf dimensions across countries that would serve as an equivalent of the American sizes for purposes of plan dimensions -- if an American shed is mostly 2x4's on 16" centers with 1/4" 4'x8' sheathing (some of those being real measurements and some nominal), is there a well-accepted set of metric dimensions would replace those elsewhere to build the equivalent shed, and are those subject to the same kind of inconsistency?

An answer of "almost; there are three such systems battling for dominance and they are..." or "not really, everyone has their own set of numbers influenced by their own historical construction practices" or "actually, there IS an international standard known as..." would then qualify as a clearly acceptable answer.

As I say, the real question is whether we can translate something between metric and American in any reasonable way, or if we just have to count on everyone making their own adjustments.

(Let's see, in stones/furlongs/fortnights that would be...)

  • What's the motivation behind the question? Are you asking the question out of curiosity? Are you helping a friend in Spain build plans for a shed? Jul 10, 2015 at 13:03
  • Mostly curiosity, but also pondering what could be done to make this site, and published plans, more internationally useful. It's an attempt to sharpen/generalize the preceding question about converting units, which might or might not have implicitly invoked nominal measurements (I don't think the Original Poster ever clarified that). If folks feel it isn't useful to have as an Answer for reference we can kill it, but it seemed worth asking given SE's stated goals.
