Dimensions 1:1 Mod (1.21.1, 1.21) – Sync Coordinates Across All Dimensions in Minecraft

download Skip to Downloads

The Dimensions 1:1 Mod (1.21.1, 1.21) redefines the way dimensions are linked in Minecraft by enforcing a 1:1 coordinate ratio between the Overworld, Nether, and other dimensions. In the vanilla game, traveling 1 block in the Nether moves you 8 blocks in the Overworld. This mechanic is powerful for fast travel but can complicate portal placement and coordinate tracking. This mod removes that ratio entirely, making travel and portal syncing simpler and more intuitive for players who prefer a unified coordinate system.

Dimensions 1:1 Mod

Features:

  • 1:1 Coordinate System Across All Dimensions
    Removes Minecraft’s default 1:8 ratio between the Nether and the Overworld. Moving 1 block in the Nether is now equivalent to 1 block in the Overworld.
  • Consistent Portal Linking
    Portals in the Nether and Overworld will now align to identical coordinates, making portal networks easier to manage and less prone to mislinking.
  • Simplified Navigation
    Coordinates across all dimensions now match exactly, which is especially helpful for builders, redstone engineers, or players who want dimensional symmetry.
  • Perfect for Custom Servers or Creative Mode Projects
    Useful for mapmakers, SMP servers, or anyone who wants more predictable dimension behavior.
  • Built for Fabric mod loader. Compatible with Minecraft 1.21.1 and 1.21.

FAQs

Does this mod affect only the Nether?

No. It applies the 1:1 ratio to all dimensions where applicable, not just the Nether.

How does it affect portal travel?

Portals now link between dimensions using the exact same coordinates, eliminating the need to divide or multiply coordinates when syncing them.

Is it server-side or client-side?

This is a server-side mod. Clients joining a server running the mod don’t need to install it unless the server requires it for additional features.

Does it work with other dimension-related mods?

It depends. Most dimension mods will work fine, but mods that customize portal behavior or add teleport mechanics may require testing for compatibility.

Can I still use the Nether for fast travel?

No. The fast travel mechanic is disabled—travel distances are now identical across all dimensions.
