Studwork question re door frame.

[speccy]

Just putting up a studwall and now need to add a double width door frame. Struggling to find the right timber am i being stupid?

Timber is 98x45 actual size + 12.5(x2) +3(x2)mm skim either side = 129mm

Looking for planed timber 130mm wide doesn't seem the norm?!

Get some cut to size? My local timber merchant will cut any size you like.

Thanks Jonbey worked it out in the end. I was looking for 133mm width timber but no of course that's 32x138mm timber!! So once i actually looked for what i wasn't looking for i found it

Travis Perkins have it for anyone wondering it's 32x138x4.2m (Finished size 27x133!!)
