We always endeavour to use 900mm x 1800mm plasterboards on ceilings. 900mm 2400mm as a last resort.
Look at the centering on your timbers. 450mm (18") centres would indicate 900mm x 1800mm plasterboards and 400mm or 600mm (16"/24") centres would indicate using 900mm x 2400mm plasterboards.
Staggering the joints (essential) will mean a wee bit more wastage, so factor this in.
