Well, I'm in Sweden but here I ask for the
notation/convention used in the Anglo-American
world, e.g. in the UK and North America.


TxWxL (thickness/width/length) is pretty-much the way measurements are
given in US/NA although as another noted construction lumber is referred
to by its nominal dimensions rather than exact measurements (despite the
silly/frivolous lawsuits slapped on by the tort-chasing lawyers).

It's not just construction lumber that's specified by it's nominal
size. Finished lumber is also specified by it's nominal thickness (1"
is really 3/4", 5/4 is really 1-1/8", etc.). However, boards are
normally specified in board-feet, rather than W/H/L.

If one is providing dimensions for a piece that is a part of a piece of
furniture or other fitted use then exact dimensions are, of course,
mandatory.

It would be assumed that a single dimension would apply to all; don't
believe that would ever be a source of confusion although it never hurts
to be explicit. In US, as so much is still in English units in the
construction field, having the decimal points would make it essentially
universal to be metric. In Canada, "not so much"...
