Nether Portal Calculator

The Nether Portal Calculator on Minefort helps you seamlessly sync your portals between the Overworld and the Nether in Minecraft. Simply enter your Overworld coordinates into the tool, and it will instantly generate the exact Nether coordinates you need. By following the calculator’s results, you’ll create perfectly aligned portals that make fast, efficient travel between dimensions a breeze. No more trial-and-error or wasted resources—this user-friendly tool takes the guesswork out of portal placement, ensuring you spend less time troubleshooting and more time exploring.

Instructions

  1. Build the frame of the portal in the Overworld at your desired location without lighting it.
  2. Step into the frame and find the coordinates (X Y Z) of the frame on the F3 screen. Remember the direction you're facing when you're walking into the portal as well. (We'll use this for getting a smooth transition between the Overworld and the Nether).
  3. Enter the X Y and Z you got in step 2 into the calculator ("Overworld coords").
  4. The Nether coordinates of the portal will appear on the right ("Nether coords").
  5. Finish the portal by lighting it and go through it.
  6. Go to the exact coordinates you got in step 3.
  7. Replace the block you are standing on with an obsidian block.
  8. Face the same direction you got in step 2 using the F3 screen.
  9. Replace another block in the floor to your left or right with an obsidian block. You have now built the base of your new Nether portal.
  10. Build the rest of the Nether portal and light it.
  11. Go back to the Nether portal you first came through, and destroy/disable it.
  12. Go back to the Overworld through your newly built Nether portal.
  13. You should now have correctly linked your Nether portals.

Notes

  • You can link up as many portals as you want, there is no limit.
  • While the portals don't have to be precisely lined up, it is best to align them up correctly to prevent linking issues.
  • When portals are not correctly linked, going through one portal in the Overworld may result in entering the Nether in another portal. Portals can link up to other portals within a 1024 block radius for the Overworld, or a 128 block radius for the Nether on both X and Z axis.
  • You can reverse this method and start in the Nether by swapping the "Overworld" and the "Nether."
  • When getting the coordinates from the F3 screen, you can ignore the decimals and round the numbers down.
  • The height at which you place the portals (Y) matters! When building a portal near the build limit in the Overworld, the portal in the Nether will be near the ceiling.
  • Additionally to the Nether Portal Calculator, there is a 3D distance calculator for getting the precise distance between Nether portals.
