Minecraft Nether Portal Calculator: Coordinate Linker

Find the exact coordinates to link your Overworld and Nether portals.

General Engine

We are using the general calculation engine for Nether Portal Calculator.

The 8:1 Ratio

Space in the Nether is compressed compared to the Overworld. For every 1 block you travel in the Nether, you travel 8 blocks in the Overworld. This makes the Nether the fastest way to travel long distances.

How to Link Portals

  1. Note down the X, Y, and Z coordinates of your Overworld portal.
  2. Divide the X and Z coordinates by 8.
  3. Keep the Y coordinate (height) roughly the same, though it matters less.
  4. Build your Nether portal at these calculated coordinates to ensure they link perfectly.

Portal FAQs

Why did my portal spawn a new one?

If you don't build the matching portal at the exact divided coordinates, the game searches for the closest one. If none are close enough, it generates a new one, breaking your link.

Does Y level matter?

Y level (height) is not divided by 8. However, if multiple portals are close in X/Z, the game will pick the one closest in height.
