Chunk Basics

In Minecraft, when you first start playing, the world is divided into small areas called chunks. Chunks are 16 blocks wide, 16 blocks long, and 256 blocks high. The game loads these chunks around you as you move through the world, and unloads them when you’re far away.

What is a Chunk?

Minecraft is divided into chunks which are 16×16 blocks (measured from the base of the block to the top). Chunks are generated around you as you explore and discovering new areas. The map in your game shows these chunks as small squares.

How Big is a Chunk?

In Minecraft, a chunk is a 256 block tall 16×16 segment of a world. Chunks are the method used by the WorldEdit tool to divided up a world on a server.

Chunks are subdivided into 16×16 sub-chunks, or sections. When chunks generate, they generate in sections. When editing chunks with WorldEdit, you edit sub-chunks, which can be thought of as “mini-chunks.”

The term “chunk” was coined by members of the MCPE Community, and has been widely accepted since then.

Chunk Loading

There are various methods of chunk loading in Minecraft Bedrock. The most common method is to use the /forceload command, which loads all nearby chunks. This can be useful if you want to keep a certain area of your world loaded at all times.

Chunk Loading in Bedrock

Chunks are the basis for Minecraft’s “infinite” saved game format. Chunks are 16 blocks wide, 16 blocks long, and 256 blocks high, which totals 4,096,000 cubic blocks – 64 times as many as in a Region. Bedrock Edition saves chunks in various files called region files.

Chunk Loading in Java

Java Edition has 1-block-thick “chunks” that are 16?16?16 blocks in size. Bedrock Edition has 3-block-thick “chunks” (also called sections) that are 16×16×16 blocks in size. When you load a world in Bedrock Edition, only the visible chunks are loaded. The game doesn’t load chunks that aren’t needed, which helps to save memory and improves performance. When you’re far away from the spawn point, the game only loads the chunks that are close to you.


After conducting our experiment, we have come to the conclusion that a chunk in Minecraft bedrock is approximately 1 block by 1 block.
