How do you calculate the size of a door?
I made mine a little smaller. But only because I took the time to make sure it was perfectly square. The calculation is: size of the door + 3mm gap both sides + thickness of the lining (usually 27mm) x 2 + an amount to shim (5-10mm depending on accuracy) x 2. You will need that calculation when you consider the height too.
How thick should a Door liner be?
The normal thickness for door linings is usually about 1 1/8". I personally would pack out with timber and then fine tune with the shims if needed. 1 1/8" is 27.5mm to less than a mm but I agree with the timber packing, some 18mm ply either side should do it.

1 1/8" is 27.5mm to less than a mm but I agree with the timber packing, some 18mm ply either side should do it.

With 100mm block walls is it possible to dot and dab and stay correct for skimming using 12.5mm plasterboard and 140mm door linings.
jbonding
youve got 20mm either side plenty of room aslong as the blockwork is flat.
legs-akimbo
Its a no no to use 12.5......three eighthts ( 9.5mm) are standard for dot and dab. Of course you can use half inch (12.5mm) but not necessary.
paulandlaura
Didn't really answer my own question, I was thinking aloud. Without your and jbonding's most amusing discussion, I would probably not have used 9.5 without a pro say so. I am sure it must be really common for DIY,ers who do want to make a decent fist of it, over-spec in ignorance.

Your most welcome Cant speak for the testosterone fuelled chimp though!
How thick should I plaster a wall?
What you want is the frame to be flush with the plaster when finished so the trim can go on with least problems. The only decision is how thick to make the plaster. That rather depends on the straightness of the wall. If it is pretty good, you could probably get away with 2mm, but more uneven would need 4mm per side. I'd probably err on the side of caution with 3mm each side. That gives the plasterer something to work with. You could then either plane it down or add more caulk to the trim. What you don't want is it too small.
