How much RAM do I need for my Minecraft Server?

In broad terms, the greater the number of addons (mods/plugins) and players a server accommodates, the higher the RAM demand becomes.

The RAM requirements for Minecraft servers can vary depending on their specific purpose and configuration. RAM serves as the server's memory and plays a critical role in determining how many tasks the server can effectively manage simultaneously.

Insufficiently allocating the required amount of RAM to a Minecraft server can lead to performance issues. Therefore, it's crucial to comprehend the factors that impact RAM usage and determine the appropriate amount needed.

As a general rule of thumb, the more addons (mods/plugins) and players a server supports, the more RAM it will need.

Extra information
 
It's important to highlight that various settings can influence the server's RAM requirements, with the most significant factor being the server's View Distance. Increasing the View Distance results in more chunks being loaded simultaneously, placing an exponential strain on the server. To mitigate lag, you can delve deeper into configuring your server. here.
 
You have the flexibility to modify your server's resources at any point, enabling you to increase or decrease your RAM as needed with immediate effect. Detailed instructions for this process are available in our Knowledgebase article. here.
