Choose the setup closest to your plan to get a cautious starting range. This estimate is a planning guide; actual memory use depends on server software, version, world activity, Java settings, and hosting environment.

—
Treat this as a starting allocation, not a performance guarantee. RAM does not replace a fast CPU, good server software, sensible view distance, or a healthy world. Leave memory headroom for the operating system and other services, then monitor actual usage, garbage collection, and tick performance as your world grows.
