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.
