Stud wall plasterboard screw spacing?

[StephenStephen]

I do seem to like making life hard for myself!
What screw spacing do I need for this sheet of plasterboard:
- In general?
- Around the cutouts?

I know I'll put thousands in if I don't ask advice first!

Many thanks, Stephen

Just make sure no unsupported area of more than 200mm.
