How Nether Portals Work
Overworld → Nether: Divide X and Z by 8. Y stays the same.
Nether → Overworld: Multiply X and Z by 8. Y stays the same.
Portal Linking Tips:
- Overworld portals must be at least 128 blocks apart to link to different Nether portals
- Nether portals must be at least 16 blocks apart
- Always build portals within ±128 blocks of the Y axis limit in the Nether (Y 0–127)
- The game searches a 128-block radius in Overworld for an existing portal
To avoid linking problems, make sure that the Overworld portals are at least 8 blocks apart or the Nether portals 1 block apart, provided that they are linked up correctly.
