How do I create a flat (superflat) world? — Minecraft

Q: Which `level-type` value do I use?

Use flat on older Minecraft versions and minecraft:flat on newer ones. If one doesn't work, try the other for your version.

Q: Do I have to reset the world?

Yes — level-type only affects newly generated terrain, so the existing world must be reset for the flat type to apply.

Q: Can I customise the layers?

Yes — generator-settings in server.properties defines the layers and biome. Presets from the in-game superflat editor can be pasted there.

How do I create a flat (superflat) world?

A flat (superflat) world is perfect for creative builds, minigames, and testing. You create one by setting the world type in server.properties and letting the server regenerate. Here's the full process.

How to make it flat

The world type is controlled by level-type in server.properties. Setting it to flat and then regenerating the world gives you a superflat map instead of normal terrain. Because the setting only applies to newly generated terrain, you reset the world folders so it takes effect.

Step-by-step

Stop the server.
In Files, open server.properties and set level-type=flat (older versions) or level-type=minecraft:flat (newer versions).
Reset the world folders (delete or rename world, world_nether, world_the_end) so it regenerates.
Start the server.

Tip: To customise the flat layers, set generator-settings accordingly, or design a layout using an in-game superflat menu/tool and copy the preset in.
