How Much RAM Does a Medieval Horizons (Distant Horizons) Server Need?
Medieval Horizons is a medieval Vanilla+ pack on Fabric 1.21.1 built around Distant Horizons, which renders terrain far beyond vanilla chunk limits so players can see sprawling medieval landscapes from a hilltop castle — see the Medieval Horizons pack page for the full mod list. Here's how much RAM to give the server depending on group size. Finnish players: Minecraft-palvelin hosting is our native-language page. German players: Minecraft-Server mieten covers the same hosting auf Deutsch. Svenska spelare: Hyra Minecraft-server täcker samma hosting på svenska.
4 GB
Bare minimum. Workable for solo play or a very small group testing the pack, but with little headroom once Fabric, Distant Horizons, and the rest of the mod list are all loaded alongside active world generation.
6 GB
Best starting point for most servers. This matches Medieval Horizons' own recommended RAM floor and comfortably covers the Fabric loader, the medieval content mods, and normal play for a small-to-medium group.
8 GB
Safer for a mid-size, active group — several players exploring and building simultaneously, with more world chunks kept warm on the server side.
12 GB
For 10+ players or a long-running world. Medieval Horizons worlds tend to sprawl as settlements and keeps get built out, and a bigger explored area means more loaded chunks and entities for the server to track over time.
