How Much RAM Does a Minecraft Server Need?
RAM by Server Type
- Vanilla/Paper (1-10 players): 2-3GB
- Vanilla/Paper (10-30 players): 4-6GB
- Light Modpacks: 4-6GB
- Heavy Modpacks (ATM9, RLCraft): 8-12GB
- Large Networks: 12-16GB+ per server
Factors Affecting RAM Usage
- Player Count: More players = more loaded chunks and entities
- View Distance: Exponentially increases memory with distance
- Plugins/Mods: Each adds memory overhead
- World Size: Larger worlds need more cache
- Server Software: Forge/Fabric need more than Paper
