What the minecraft nether portal calculator solves
Use this Nether portal calculator to line up portals cleanly. Overworld X/Z divided by 8 gives Nether X/Z; Nether X/Z multiplied by 8 gives Overworld X/Z.
Formula
How to use it
- Choose conversion direction.
- Enter X and Z coordinates.
- Build or move the paired portal near the target X/Z.
How to read the answer
Y coordinate is not scaled by 8. X and Z are the important portal-linking coordinates for the Overworld and Nether scale.
Common mistakes and edge cases
- Only X and Z use the 8:1 scale.
- Rounding can affect exact portal placement, so test nearby blocks if linking is stubborn.
- Existing portals can steal the link if they are close enough.
Worked examples

Frequently asked questions
Why divide by 8?+
Minecraft Nether travel uses an 8:1 X/Z scale compared with the Overworld.
Do I convert Y?+
No. Y height does not use the 8:1 coordinate scale, though height can affect where portals fit.
Why did my portal link wrong?+
A nearby existing portal may be closer to the target search area. Move or rebuild portals carefully.
