How it's calculated
Nether X,Z = Overworld X,Z ÷ 8 (Y unchanged)
Divide Overworld X and Z by 8 to find the linked Nether coordinates; multiply Nether by 8 to return to the Overworld. Y (height) is identical in both dimensions.
Common values
| Overworld X/Z | Nether X/Z |
|---|---|
| 80 | 10 |
| 800 | 100 |
| 1600 | 200 |
| -400 | -50 |
Common questions
What is the Nether portal ratio?
It is 8 to 1 on the X and Z axes. Divide Overworld coordinates by 8 to find the matching Nether spot. The Y height stays the same.
Why do my portals not link up?
Portals link to the nearest existing portal within a search range. Building both at the calculated coordinates keeps them paired correctly.
