What size timbers for stud wall?

Guesses

I thought one used 4x2 timbers for stud walls, but all I'm finding online is 38x89mm (3.5x1.5 inches).

Indeed, the stud wall I'm taking down used 4x2.

Rootle around online, finds a phone number & phone them & ask.

Claim to be an apprentice if you feel a bit bashful. They sell the stuff, someone will know what it is properly used for, they can advise you.

Although if there's 2" by 4" there already, I'd try to stick with that. A real staffed-by-humans lumberyard may be more sympathetic than an online sales system, but Sundays slightly less so.

That's the studwork CLS timber and will be be more than suitable for non-load bearing stud wall.

Remember that planed timber is, strangely, sold by the size it was before they planed it. It used to drive a Dutch colleague of mine wild. If you buy a bit of " 4 x 2" planed it will be quite a bit smaller than " 4 x 2 " sawn.

So the popular 38 x 89 CLS probably was 4 x 2 before they planed it and rounded the corners.

A stud wall I'm working on is constructed from 3x2 timber.

4x2 certainly used to be the standard back in the old imperial measurement days but a change to metric approximate equivalent has changed all that.
