Minecraft RAM Calculator
How much RAM do I need? Answer four questions to get an estimate, then see compatible hosting.
How this estimate works
The estimate starts from a baseline for the server type, then adds memory for players, plugins or mods and view distance above 10 chunks. It is rounded up to a common plan size. Real usage depends on world size, farms, redstone and the exact modpack, so treat the result as a starting point and watch your server’s memory graph.
