The X (east/west) coordinate of your portal location.
The Z (north/south) coordinate of your portal location.

Inner width of the portal opening. Minimum 2, total frame minimum 4.

Inner height of the portal opening. Minimum 3, total frame minimum 5.

Corners are optional - portals work without them but a full frame looks cleaner.

Nether portal location: X=100.0, Z=50.0

  • Build your Nether portal at X=100.0, Z=50.0 to link it with your Overworld portal at X=800, Z=400.
  • You need 14 obsidian blocks for a 4x5 frame (corners included).
  • Taking the Nether shortcut saves you approximately 783 Overworld blocks of travel.
  • Keep your Overworld portals at least 33 blocks apart to prevent the game from linking them to the wrong Nether portal.

Next stepOnce you have both portals built, test the link by walking through one and checking the coordinates on the other side match your calculation.
