When setting up a Minecraft server, one of the most important factors is RAM allocation. The amount of RAM your server needs depends on:
Number of players
Plugins and mods
World size and complexity
If you allocate too little RAM, your server may lag or even crash. Too much RAM, however, can be unnecessary and costly. So, let’s break down how much RAM you actually need.
1-5 Players (Vanilla Minecraft, No Mods/Plugins) → 2-4 GB RAM
10-20 Players (Lightly Modded/Plugin Server) → 4-8 GB RAM
50+ Players (Heavy Modded Server, Large World) → 8-16 GB+ RAM
Use PaperMC instead of Spigot/Bukkit – It improves performance.
Preload chunks with Chunk Pregenerator – Reduces lag spikes.
Optimize entity limits – Too many mobs cause lag.
Use performance-boosting plugins – Such as Spark, ClearLag, and EntityTrackerFixer.
Host with a reliable provider – Cheap hosting can ruin server performance.

Minecraft Server RAM Requirements
| Server Type | Players | Recommended RAM |
|---|---|---|
| Small Vanilla Server | 1-5 | 2-4 GB |
| Medium Server (Few Mods/Plugins) | 10-20 | 4-8 GB |
| Large Server (Many Mods/Plugins) | 50+ | 8-16 GB+ |
Detailed Breakdown:
1-5 Players (Vanilla Minecraft, No Mods/Plugins) → 2-4 GB RAM- Ideal for small private servers.
- No mods or plugins required.
- Works well on standard hosting plans.
10-20 Players (Lightly Modded/Plugin Server) → 4-8 GB RAM- Some plugins like Essentials, WorldEdit, and LuckPerms.
- Modded servers with lightweight packs.
- Requires a good CPU for smooth gameplay.
50+ Players (Heavy Modded Server, Large World) → 8-16 GB+ RAM- Big servers with many plugins and custom worlds.
- Uses large modpacks (FTB, Pixelmon, etc.).
- Needs high-performance hosting to prevent lag.
