How Big Would a Fully Loaded Minecraft World Be?

The question of how big a fully loaded Minecraft world would be is more complex than it initially appears. The short answer, based on the theoretical limits of the game, is approximately 60 Petabytes (PB). However, this represents a completely filled world, which is practically impossible to achieve through normal gameplay. In reality, the average Minecraft world is far smaller. Let’s delve into the factors that contribute to this immense potential size and explore the more realistic scenarios of world sizes players typically encounter.

Understanding Minecraft World Size

Minecraft’s world generation system is procedurally generated, meaning the terrain is created on the fly as the player explores. This system allows for vast, seemingly endless worlds. But there is a limit, imposed by the game’s mechanics and how it stores world data. A fully loaded world would mean every single possible chunk (a 16×16 block area extending from the bottom to the top of the world) within the game’s boundaries has been generated and contains data.

The game’s terrain generation relies on “chunks”. These are 16×16 horizontal sections extending from the very bottom to the very top of the world, all the way up to the build limit of 320 blocks in height. All blocks within this space are stored within the chunk’s data.

Factors Influencing World Size

Several factors impact the storage size of a Minecraft world:

• Chunk Generation: Every time a player ventures into unexplored territory, new chunks are generated and saved to the disk. The more the player explores, the bigger the world save becomes.
• Block Data: Each block within a chunk requires storage space to define its type, properties (like orientation or waterlogged state), and metadata. The more complex and diverse the block data within a chunk, the more storage space it occupies.
• Entity Data: Entities, such as mobs (creatures), items, and vehicles, also take up storage space. A world filled with complex contraptions, animal farms, and densely populated villages will have a larger file size.
• World Generation Settings: Certain world generation settings, like amplified terrain or large biomes, can lead to more complex landscapes, resulting in bigger chunk sizes.

The Theoretical Limit: 60 Petabytes

The theoretical limit of 60 Petabytes is based on the following considerations:

• World Border: Minecraft worlds are not truly infinite. There’s a world border that prevents the player from loading chunks beyond a certain point.
• Data Storage: The game stores each block with 12 bits of data in the .mca format.
• Chunk Size: A chunk is a 16x16x256 area of blocks.
• Calculation: Considering the theoretical limits of the game, it’s possible to calculate the maximum possible size. The number of potential chunks within the world border, multiplied by the storage required for each chunk, results in approximately 60 Petabytes for a fully loaded world.

The Reality: Much Smaller Worlds

In reality, Minecraft worlds rarely exceed a few Gigabytes (GB) in size. A typical single-player world, extensively explored, might reach 1-5 GB. Multiplayer worlds, particularly those with many active players building and exploring, can grow larger, perhaps reaching 10-20 GB. The vast discrepancy between the theoretical limit and the practical size comes down to how the game handles chunk generation. Players don’t explore every single chunk in the world. The world border is too far away. Because only a small amount of space is explored, only that space will need to be stored.

Worlds on the 2b2t server, known for its vast history and extensive player-driven modifications, represent some of the largest Minecraft worlds. Such worlds can grow to hundreds of gigabytes or a few terabytes. But even 2b2t hasn’t fully loaded everything, which is why only a small percentage is ever explored.

Frequently Asked Questions (FAQs) About Minecraft World Size

Here are some frequently asked questions about Minecraft world size that address common misconceptions and provide deeper insights:

1. Is a Minecraft world truly infinite? No, Minecraft worlds are not truly infinite. They have a world border that limits the loading of chunks. Although the world generation system allows for vast, seemingly endless landscapes, the game mechanics have a boundary.

2. How much space does a typical Minecraft world take up? A typical single-player Minecraft world might take up anywhere from 30 MB to several Gigabytes depending on how much the player has explored and built.

3. What is a chunk in Minecraft? A chunk is a 16x16x320 area of blocks that the game uses to generate and store the world.

4. How many MB is a chunk in Minecraft? A chunk can vary in size, but a maximum size on an 32x16x32 chunk area is 96MB per mcanvil-file.

5. How much RAM do I need for a Minecraft server? The amount of RAM needed for a Minecraft server depends on the number of players and the complexity of the world. 2GB of RAM may be enough for a small server of a few friends, while servers hosting many players may need 16GB or more.

6. Is 16GB of RAM enough for a Minecraft server? 16GB of RAM is generally enough for a medium-sized Minecraft server with up to 100 players, especially if you are using a Vanilla Minecraft. Modded servers will take up more space.

7. How much does a 100-person Minecraft server cost? A server for 50-100 players typically requires 4-10 GB of RAM, costing around $20-$40 per month.

8. How big is a Minecraft block in real life? One Minecraft block is equivalent to one cubic meter in real life.

9. How many diamonds are in a chunk? Each chunk has the potential to spawn from 1 to 10 diamond ores.

10. What is the maximum diamond vein size in one chunk? Each 16×16 chunk spawns one vein of up to 8. These can spawn on the border of the chunk, and sometimes two veins in different chunks spawn touching so they appear to be one vein, with a max size of 16.

11. What causes the Far Lands? The Far Lands were a terrain generation bug in older versions of Minecraft, resulting from errors in noise generation algorithms. This has been fixed.

12. Do Minecraft worlds take up a lot of storage space? Minecraft itself doesn’t take up much space (less than 1GB), but the save files containing world data can grow to several gigabytes in size.

13. What is the 2b2t server and how big is its world? 2b2t is an anarchy Minecraft server known for its long history and large world. Its world has grown to multiple terabytes in size, but is less than 1% explored.

14. Can a Minecraft server hold 1000 players? It’s extremely difficult and expensive to host a server with 1000 concurrent players without significant performance issues. Minecraft servers typically run on a single thread, limiting the server’s processing capability.

15. Is the world of Minecraft bigger than the universe? No, that statement is inaccurate and likely intended as hyperbole. The observable universe is vastly larger than any possible Minecraft world.

Ultimately, while the theoretical size of a fully loaded Minecraft world is a staggering 60 Petabytes, real-world limitations and player behavior result in worlds that are significantly smaller. Understanding the underlying mechanics of chunk generation and data storage helps to appreciate the vastness of Minecraft’s potential while staying grounded in the practical realities of game performance and storage capacity.
