Small servers without mods often run on 2 to 4 GB, modpacks need considerably more. Try the calculator; your modpack’s recommendation always comes first.
Rule of thumb, not a guarantee. Your modpack’s recommendation comes first.
How we calculate
- Vanilla and plugins start at about 2 GB.
- Mods start at about 4 GB.
- Each player adds some RAM (more with mods).
- Large modpacks get a surcharge.
More RAM is not always better
Too much RAM can slow garbage collection. A good CPU and the right Java version matter more. See Rent a Minecraft Server.
Frequently Asked Questions
How accurate is the calculator?
It gives a rough rule of thumb, not a measurement. Real load depends on world, redstone, and mods.
Is 2 GB enough?
For a small vanilla server with few players, often yes.
Does Bedrock need less?
Bedrock servers are usually lighter. Check the provider’s specs.
