Minecraft WorldBorder Calculator
Work out the right /worldborder diameter for your player count, RAM and world type — or start from a storage or pre-gen time budget and see how big a border that buys you. Get the exact commands either way.

Players, RAM & world type
These change what a sane border actually is — a skyblock server and a 100-player SMP need very different diameters.
Pre-generating removes the runtime generation lag, so it can support a somewhat larger border comfortably.

Estimates only — world-file size and pre-gen throughput are not measured data. Adjust the slider for your own hardware.

Depends on plugins, view distance and CPU
Default 150 chunks/s — a starting point, not a benchmark. Estimate only: depends on plugins, view distance and CPU.
For reference, Wespner Minecraft hosting runs on AMD Ryzen / EPYC (Zen 4/5) CPUs up to 5.5 GHz with NVMe SSD storage — pre-generation is single-threaded, CPU-bound work, so a faster single core and faster storage both help.
