Minecraft Nether Portal Calculator
Convert coordinates between the Overworld and the Nether so your portals line up, and check whether two portals will link. Every block you walk in the Nether covers 8 in the Overworld.
Will my portals link?
If another portal is closer to the matching spot, Minecraft uses that one instead. Keep portals in the same area at least 32 blocks apart in the Nether so they don't cross-link.
How to use the Nether Portal Calculator
- Enter the coordinates of your portal in the Overworld or in the Nether.
- Read off the matching coordinates in the other dimension. That is where to build the second portal.
- To check two portals you already have, enter both sets of coordinates and the tool tells you whether they will link.
Common questions
How do Nether coordinates work?
Every block you travel in the Nether covers 8 blocks in the Overworld. So you divide Overworld x and z by 8 to get Nether coordinates, and multiply by 8 to go back. Height (y) is not scaled.
Why does my portal take me to the wrong place?
When you go through, Minecraft looks for an existing portal near the matching spot: within about 128 blocks in the Overworld and 16 blocks in the Nether. If another portal is closer than yours, it uses that one.
How far apart should portals be?
Keep portals in the same area at least 32 blocks apart in the Nether, so each one links to its own partner and they do not cross over.
Does this work for Bedrock Edition?
The 8 to 1 scale is the same. The linking distances used here are Java Edition’s, from 1.16 onwards, so the link check may not match Bedrock exactly.
