Convert Overworld coordinates to the Nether — or Nether coordinates back to the Overworld — using Minecraft's 8:1 horizontal coordinate ratio.
Portal Coordinates
Minecraft uses an 8:1 horizontal coordinate ratio between the Overworld and Nether. One block traveled in the Nether corresponds to eight blocks in the Overworld on the X and Z axes.
Overworld → Nether
X ÷ 8 · Z ÷ 8
Nether → Overworld
X × 8 · Z × 8
The calculator shows both the exact mathematical result and a nearest-block result for practical portal placement. Negative coordinates work normally.
Divide the Overworld X coordinate by 8 and divide the Overworld Z coordinate by 8. For example, X 800 and Z -1600 becomes X 100 and Z -200 in the Nether.
Multiply Nether X by 8 and multiply Nether Z by 8. The calculator can switch direction instantly with the Swap button.
No. The 8:1 coordinate conversion applies to the horizontal X and Z axes. Y is not scaled. When several portals are close together, vertical placement can still influence portal linking.
Converted X/Z coordinates are the correct starting point, but Minecraft can link to another nearby portal. Moving portals closer to the matching converted coordinates and considering vertical distance can help separate portal pairs.
