Terraria Server RAM: How Much Do You Actually Need?
How much RAM does a Terraria server need? Officially ~500 MB for small worlds — plus real-world values for large worlds, many players and tModLoader.

How much RAM does a Terraria server need?
The official figure is refreshingly modest: around 500 MB of RAM for a small world. That makes Terraria one of the most frugal server games out there. You mainly need more RAM for large worlds, many concurrent players and tModLoader with mod packs.
RAM recommendations at a glance
Beyond the official figure for small worlds: the following values for bigger setups are real-world hosting experience, not official numbers from Re-Logic.
| Scenario | RAM recommendation | Source |
|---|---|---|
| Small world, few players | ~500 MB | Official figure |
| Medium/large world, vanilla | 1–2 GB | Experience value |
| tModLoader with mod packs | 2–4 GB | Experience value |
Note
Actual usage depends on world size, player count and (with tModLoader) heavily on the installed mods. Large content mods can push RAM usage well beyond the table above.
Which RespawnHost package fits?
Terraria servers at RespawnHost start at €4/month with 2 GB RAM — comfortable for vanilla worlds of any size, with headroom for plenty of players.
| Setup | Recommendation |
|---|---|
| Vanilla, small to large world | Entry package (2 GB) |
| tModLoader with many/large mods | Bigger package (4 GB and up) |
Both billing models are available: fixed package (flat monthly price) or Pay-Per-Use (per second, only while the server runs). You can switch packages anytime if your mod pack grows.
Tip
Starting small pays off: begin with the entry package and watch the live RAM usage in the panel. Upgrading is faster than overpaying.
Frequently asked questions
Is 2 GB of RAM enough for a Terraria server? For vanilla: yes, comfortably — the official requirement is ~500 MB for small worlds, and even large vanilla worlds typically stay under 2 GB in practice.
How much RAM does a tModLoader server need? As a rule of thumb from experience: 2–4 GB depending on the mod pack. Large content mods (and many mods at once) can need more — the live display in the panel shows the real usage.
Does player count affect RAM usage?
Yes, but moderately — world size and mods weigh more. The default of 16 slots (maxplayers, see the configuration guide) is easily handled by the entry package.
