Plasterboarding ceiling - use large or small boards?

[Simplez]

To plasterboard a ceiling is it better to use smaller 1800 x 900 sheets or bigger 2400 x 1200 sheets.

It will be skimmed over so I should be ok with square edge and using scrim tape on every edge?

The previous ceiling was removed so the ceiling joists are exposed.

either. as long as you stagger them . preferably with the length of the board opposing the joist. and make sure every board edge lands on a timber.
also be sure to use 12.5mm boards.

You mean the boards go across the joists and not in the same direction as the joists.
