What it does

The mod ships as a datapack that increases world height to 1024 blocks, so builders get vertical room beyond the vanilla limits. Terrain generation is extended in four dimension types: the Overworld, the Nether, the End and amplified worlds. Each part of the extension is a separate setting that a server owner can keep or remove.

The server needs the mod to apply the taller worlds, while players may add it on the client but do not have to. Files are published for Fabric, Forge, NeoForge and Quilt, for 1.21 and 1.21.1, and the code is released under the MIT License, though the project is not open source. Latest builds are version 0.0.1 for 1.21.1, dated 2024-10-21, and the first and last updates share that date.

Key features

Taller world height
A datapack raises the world height limit to 1024 blocks for newly generated terrain.
Extended Overworld
Overworld generation is extended upward and downward so the taller height has terrain to fill.
Extended Nether
The Nether receives the same height extension, adding room above and below the familiar ceiling.
Extended End
End generation is extended as well, giving the outer islands a taller space to populate.
Extended amplified worlds
Amplified terrain is also covered, so worlds using that preset reach the new height.

How it compares

Full comparison

Extended World Height (Y=2032) is released under the BSD 3-Clause License, targets 1.20 – 26.3 and is server required with an optional client, so it reaches a much higher limit. Extended World Height (Y=1024) is also released under the BSD 3-Clause License, with the same loaders and version range, and it sets the height to 1024 as well. Higher Nether is server-side only, released under the GNU General Public License v3.0 only, and covers 1.20 – 1.21, so it changes only the Nether.
