Which setup for your Minecraft server?
In a few seconds, estimate the RAM your Minecraft server is likely to need (Vanilla, Paper, Forge, heavy modpack, players, plugins). We rely on our internal benchmarks and feedback from our customers to point you to a suitable plan, without undersizing.

How we compute RAM
Our formula is deliberately conservative: most free calculators under-size Minecraft servers and cause OutOfMemory crashes. We prefer to recommend 8 GB when 6 would barely fit, rather than the other way around.
Base per server type: Vanilla 2 GB, Paper/Purpur 2.5 GB, Forge/Fabric 4 GB, Heavy modpack 6 GB. These values match RAM we observe on our clusters for a freshly booted empty server with one loaded world, as part of our internal benchmarks.
RAM per player: Vanilla 200 MB, Paper 200 MB, Forge 300 MB, Modpack 350 MB per peak player, consistent with our measurements (roughly 0.2 to 0.5 GB per active player depending on server type). This includes chunk loading, inventories and entities. Above 25 concurrent players we apply diminishing returns (chunks overlap).
Additional plugins & mods: A bonus is added: +0.5 GB (1-10 Paper plugins) up to +4 GB (30+ plugins including Dynmap/BlueMap/CoreProtect). For Forge/modpacks: +1 to +5 GB depending on side-mods. Mapping and logging plugins (Dynmap, CoreProtect) are often very RAM-heavy according to our customer feedback.
Safety margin: +30% added to the total. We deliberately recommend at least 30% headroom to absorb spikes: raids, auto farms, explosions, massive chunk generation, simultaneous logins. Without a margin, a server running at 95% RAM crashes at the first intense event.

Frequently asked questions about Minecraft RAM
Everything you need to know before picking a plan.
How much RAM for a Vanilla Minecraft server?
For Vanilla with 5-10 friends, we usually recommend about 4 GB in practice. From 20 players, plan for 6 to 8 GB. Beyond 30 players, 10 to 12 GB. Vanilla is more efficient than modpacks but consumes more than older estimates suggested: modern players load 200-500 MB each on average depending on view distance.
How much RAM for a Paper server with plugins?
Paper/Purpur is highly optimised but plugins add up. For 10-20 players with 10 common plugins (EssentialsX, LuckPerms, WorldEdit), 6-8 GB is comfortable. For 30-50 players with 20-30 plugins including heavy ones (Dynmap, CoreProtect, DiscordSRV), aim for 10-12 GB. For 100+ players, 16 GB minimum.
How much does a big modpack like RLCraft or ATM9 consume?
Large modpacks start heavy. Official and community recommendations: RLCraft 6-8 GB for 2-5 players, 12 GB for 10 players. All The Mods 9/10: 8-10 GB minimum, 12-14 GB for 5 players, 16-20 GB for 10-20 players. GregTech and kitchen-sink packs (150+ mods) require 14-16 GB even with few players. Undersizing causes crashes, lag and world corruption.
Does view distance impact RAM?
Yes, and more than you might think. Going from 10 to 16 chunks increases RAM per player by ~50% and CPU by 50-80%. Our Ryzen 9 plans at 5.7 GHz comfortably handle 10-12 chunk view distance. For 16+ chunks with many players, pick the next tier. Tip: lowering simulation-distance to 4-6 chunks cuts entity load 2-3x.
Why a 30% safety margin?
Because a Minecraft server running at 95% RAM will hit OutOfMemory on the first XP farm, creeper explosion, raid or massive chunk generation (Nether/End portals). We deliberately recommend at least 30% headroom: 25% is often too low on modpacks or plugin-heavy servers, hence our +30% minimum.
The recommended plan is out of stock, what now?
Our stock system is real time. If the recommended plan is unavailable, you can either pick the tier just above or contact us on Discord/ticket: we can usually free a machine within 24 h or offer a Ryzen VPS with turnkey Minecraft installation.
