Nether Portal Calculator
📍 Starting location
🚪 Nether destination
The large values are exact coordinates. Block positions round down, including negative coordinates.
ℹ️ Building your portal pair
Overworld → Nether: divide X and Z by 8. Nether → Overworld: multiply them by 8. Y is not scaled.
Build a portal near the matching coordinates, then check both directions in-game. Existing portals, height differences and terrain can affect where you arrive. This calculator converts positions; it does not predict or guarantee portal links.
Works with the standard coordinate scale in Vanilla Java and Bedrock. Custom dimensions or server rules may differ.
Guide
Calculate Overworld and Nether portal coordinates
Enter the coordinates of your starting location and choose whether you are travelling from the Overworld or the Nether. The calculator shows the corresponding destination and its block coordinates. Swap direction to check the return trip.
For the standard Vanilla dimensions, divide Overworld X and Z by eight to find the Nether position. Multiply Nether X and Z by eight to find the Overworld position. Y is not scaled. The calculator also handles negative coordinates, so locations west or north of the origin remain in the correct region.
Copy the block coordinates to use while building, or copy a link to share the calculation. This conversion applies to standard Java and Bedrock worlds. Existing portals, portal search ranges and terrain can affect actual links; the calculation is a starting location, not a guarantee that two portals will connect.
