What this tool does
Enter coordinates from one dimension and get the matching location in the other. This is especially helpful when building Nether roof hubs, multiplayer travel networks, or base portals that must connect reliably.

Overworld
÷ 8 to Nether
8:1
Nether
x 8 to Overworld
The Y coordinate doesn't affect portal linking - only X and Z are used to match portals across dimensions. Build your Nether portal at the exact calculated X/Z for a reliable connection.
Linking Portals
Divide your Overworld X and Z by 8, then build your Nether portal at exactly those coordinates for a guaranteed direct link.
Chunk Alignment
Keep portals well inside a single chunk (16x16 blocks). Portals near chunk borders can link to unexpected locations.
Fast Travel
1 block in the Nether = 8 blocks in the Overworld. A 10,000-block Overworld trip shrinks to just 1,250 blocks in the Nether.
Nether Portal Coordinate Guide
Nether travel works because horizontal coordinates are scaled by eight. Enter an Overworld X and Z value to find the matching Nether portal location, or enter Nether coordinates to calculate the return point in the Overworld. This is most useful when linking bases, farms, strongholds, and long-distance tunnels.
If a portal links to the wrong place, check for nearby portals in both dimensions. Minecraft searches for an existing portal before creating a new one, so two portals that are too close together can share a destination. Building the calculated portal manually usually fixes the route.
Frequently Asked Questions
What is the exact ratio between dimensions?
Exactly 8:1. Every block traveled in the Nether equals 8 blocks in the Overworld - both Java and Bedrock editions use this same ratio.
Why do my portals sometimes link incorrectly?
Two Overworld portals that are too close may share the same Nether portal. Fix it by manually building a second Nether portal at the calculated coordinates for your second Overworld portal.
Does the Y coordinate matter for linking?
Primarily no - the game matches portals by X and Z. Y can matter if two portals share the same X/Z but differ in height; the nearest one wins.
Does this work for Bedrock Edition?
Yes. The 8:1 coordinate ratio is identical in Bedrock Edition. These calculations apply regardless of platform.
Portal Planner
Minecraft Nether Portal Coordinate Calculator
The coordinate calculator converts Overworld and Nether positions using the 8:1 ratio so you can link portals, plan hubs, and avoid accidental portal connections.
Portal linking advice
A correct coordinate is only part of portal linking. Portal height, nearby portals, search radius, and build order can affect where Minecraft connects you. Test with temporary portals before decorating the final room.
Quick questions
What is the Nether ratio?
One block in the Nether equals eight blocks in the Overworld on the X and Z axes.
Does Y level matter?
Y level can matter for portal search and placement even though the main distance conversion uses X and Z.
