Interior wall CC45 or 60?

[Danii KD]

What are the advantages/disadvantages of each?

Is any of the options preferable?

cc45. at 90 discs or cc60 at 120 discs.
different for bathroom

Yes, but there are discussions about whether one thing can hold more (for example, TV) while some say that it is not true. Does this affect the wall's ability to bear weight in any way, or is it just about the choice of gypsum board size?

Holds for TV as long as the drywall doesn't topple over

Sure, but there are discussions about whether one can hold more (for example, a TV), while some say that's not true. Does it affect the wall's ability to support in any way, or is it just about the choice of plasterboard size?

I think it's more about what kind of board.
Nowadays, since we want to have so much on the walls, it's common to put plywood before plasterboard.

It's the studs in a wall that are load-bearing. The more studs, the stronger it obviously becomes, assuming the same kind of studs are used.
But nothing becomes stronger than the fastening, either. So if a TV sits better on a wall with cc45 or cc60, it depends more on the fastening.

cc45. at 90 boards or cc60 at 120 boards.
different for bathrooms

Exactly.

And possibly you could set cc40 at 120 boards, but it's usually unnecessary.
If the wall is supposed to carry something really heavy (>50-100kg), you might want to think ahead and add extra studs or noggins in exactly the right spots, or alternatively, place an OSB or plywood board before the gypsum.

And bathroom walls have, as mentioned, their own set of rules, which you should of course read up on and follow.
