Medium spaghetti squash tends to be a little tougher in the center after cooking, and large squashes yield softer results with sweeter strands. Large squashes will take around 40-50 minutes to roast. Small-medium squashes will roast in less time.
Check after around 30 minutes or so to make sure you don't overcook them, as they will become really mushy in the middle and won't form many natural spaghetti-like strands.
