How much RAM does your server need?

Answer a few questions about your Minecraft server and we'll suggest a RAM size and the plan that fits. It's an estimate based on common hosting guidance.

1Minecraft version

2Server type

Example packs are rough guides. Mod counts change between pack versions.
You'll find it on the pack's CurseForge or Modrinth page.

A network runs a proxy (like Velocity) plus separate servers for each mode, so there's no single number. Size each backend server with this calculator, then add about 1 GB for the proxy. We're happy to help you plan it in the Discord.

How we estimate

The numbers are fitted to what modpack authors publish for their own server packs (All the Mods, Vault Hunters, Prominence II), Paper's memory guidance, and measured memory use from running servers. They cover the whole server, which needs more than the Java heap: Java needs roughly 1.5 to 2 times the memory it actually holds so garbage collection stays smooth, plus about 1 GB outside the heap. Where a pack's author gives a figure, we use theirs.

It's still an estimate. Worlds, farms and plugins vary a lot, so check your panel's memory graph after a week and adjust.
