Features:
- Raises the build limit to Y=2031
- Applies to every dimension, not just the Overworld
- Available as a mod and as a datapack
- Does not change world generation on its own
- Custom world generation packs may hardcode their own height and need adjusting
- The Tectonic datapack can be matched by setting its height values to 2096, while its mod version is not supported
- Intended for newly created worlds rather than existing saves
- Removing it on 1.17 to 1.21.1 deletes everything built above the normal build limit
- Removing it from 1.21.2 onward can corrupt the world
- Fabric, Forge, NeoForge and Quilt support
- For Minecraft 1.21.1

The vanilla build ceiling is the hardest limit most large projects run into. Skyscrapers get flattened at the top, mega-towers have to be redesigned halfway up, and anything meant to look genuinely tall ends up compressed. 2032 World Height removes that wall by lifting the limit to Y=2031, and it applies to every dimension rather than the Overworld alone.
The change is deliberately narrow: world generation itself is not touched, so terrain still looks the way it should. The one thing to watch for is other packs that write their own height values. A world generation datapack such as Tectonic hardcodes its own limits, and its datapack form can be brought into line by setting its height and logical height values to 2096, while its mod form is not supported.
This is best treated as a decision made when a world is created. Existing saves are not officially supported, and removing the extension later has consequences: on 1.17 through 1.21.1 everything built above the normal ceiling disappears, and from 1.21.2 onward removing it can corrupt the world outright. Start a fresh world with it in place, keep it installed, and the extra headroom is yours for the life of the save.
