Choosing a size.
Memory and cores are what you pay for. Start small if you're not sure, because you can change the size any time.
- Friends (4 GB, 2 cores) suits up to 10 players.
- Party (8 GB, 3 cores) suits up to 20 players.
- For your own numbers, a plain server starts at 2 GB and takes a quarter of a gigabyte per player. A modded one starts at 4 GB and takes half a gigabyte per player.
- One core carries up to 5 players, two up to 12, three up to 20, and four take anything above that.
Resizing restarts the server, and you pay the difference for the days left. The pricing page does the math for your group.
