How much RAM does your Minecraft server need?
Pick what you play and how many people join. The calculator recommends the memory and shows the price.
RAM calculator
Modpacks need more memory than vanilla, and every group of extra players adds a little on top.
How the estimate works
Each server type starts at a base amount. For every group of players on top, add 1 GB. The calculator caps at 32 GB.
| Server type | Starts at | +1 GB per |
|---|---|---|
| Play with friends | 2 GB | 15 players |
| Community server | 4 GB | 10 players |
| Modpack | 6 GB | 8 players |
| PC + console & phone | 3 GB | 15 players |
| Console & phone only | 2 GB | 20 players |
RAM questions
How much RAM does a vanilla Minecraft server need?
A few friends on vanilla usually run fine on 2–4 GB. More players, a higher view distance and large explored worlds push the need up.
Do modpacks need more RAM?
Yes. Mods load extra blocks, items and logic at startup, so modpacks need noticeably more memory than vanilla. Large packs often list their own recommendation — use that as the minimum.
Does more RAM fix lag?
Only if the server is running out of memory. Most lag comes from the CPU: many entities, big redstone builds or fast chunk generation. Memory beyond what the server uses does not raise TPS. See how to fix lag.
Does a Bedrock server need less RAM than Java?
Usually yes. The Bedrock dedicated server tends to use less memory than a Java server with the same player count. Crossplay setups run a Java server plus a translation layer, so plan for Java-level memory.
Can too much RAM hurt?
Giving Java far more memory than it needs can make garbage collection pauses longer. Start with the recommendation and add more when you actually see memory run out.
