Overworld ↔ Nether Coordinates

1 block in the Nether ≡ 8 blocks in the Overworld. Linked portals form automatically when the destination coordinates of both portals are within ±16 blocks of each other (horizontal) and ±128 blocks (Y).

Linking portal pairs

  • To force two portals to link, build both portals at the converted coordinates above.
  • When you enter an Overworld portal, the game looks for an existing Nether portal within a 256-block cube around the target coords — otherwise it spawns one near that point.
  • For perfectly-linked builds, place the destination Nether portal exactly at the converted coords before first travel.
