Minecraft Coordinate Generator Tool
Linking Minecraft Overworld and Nether portals
Plan Your Builds With Precision
The Coordinate Generator helps you map out massive builds, nether portal linkages, and circular structures before you place a single block in-game.
Minecraft relies heavily on a three-dimensional grid. Whether you're trying to perfectly link a Nether portal (divide Overworld coords by 8) or generate a perfect circle for a mob farm perimeter, doing the math manually is tedious and prone to errors.

How Nether Portals Work
The Nether operates on a 1:8 ratio with the Overworld. For every 1 block you move horizontally (X and Z) in the Nether, you travel 8 blocks in the Overworld. The Y-axis (height) remains 1:1.
This makes the Nether the ultimate fast-travel network. To link two portals perfectly so they don't cross-wire, take your Overworld portal's X and Z coordinates, divide them by 8, and build your Nether portal at exactly those new coordinates. Our tool does this math for you instantly.
Frequently Asked Questions
Do Y-coordinates matter for Nether portals?
Generally, no. The game primarily looks at the X and Z axes to link portals. However, if multiple portals share similar X and Z coordinates, the game will link to the closest one on the Y-axis.
Is the portal ratio different on Bedrock?
No, the 1:8 Nether-to-Overworld ratio is consistent across both Java and Bedrock editions.
