ARMA 3 Server RAM Calculator

ARMA 3 RAM needs depend on player count, world size, and mod/plugin load. Small private servers often work with low RAM, while larger or heavily customized servers need significantly more.

For a small private ARMA 3 setup, start around your plan minimum and monitor usage. If memory usage regularly stays high, move up one tier.
