The timber cross section dimensions aren't critical. The above are dressed dimensions. Beware that if you ask for timber of a given size, some unscrupulous swine will happily supply you undersize. When challenged they witter on about un-planed dimensions, and that's what they thought you meant.
That happened to me once, a long, long time ago.
I took my revenge.
