Distances in the Nether are eight times shorter than in the Overworld. Divide Overworld X and Z by 8 to get Nether X and Z. Height (Y) does not change in the calculation.
| Overworld X, Z | Nether X, Z |
|---|---|
| 800, 400 | 100, 50 |
| -1600, 240 | -200, 30 |
| 80, 80 | 10, 10 |
Try your own numbers in the Nether portal calculator. To go the other way, multiply by 8.
Linking two portals
Build the Nether portal at the converted coordinates and the game should link to the one you built. If the portals sit too close together, they may link differently, so keep them well apart.
