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.
