Minecraft Nether Portal Calculator
Convert X and Z coordinates between the Overworld and Nether with the standard 8:1 horizontal scale.
How Nether coordinate conversion works
Horizontal travel is scaled by 8 between dimensions. To estimate a matching Nether location, divide Overworld X and Z by 8. To return to the Overworld, multiply Nether X and Z by 8.
| Starting point | Conversion | Example |
|---|---|---|
| Overworld → Nether | Divide X and Z by 8 | 800, −400 → 100, −50 |
| Nether → Overworld | Multiply X and Z by 8 | 100, −50 → 800, −400 |
Rounding and exact placement
When division produces a decimal coordinate, use it as a target area rather than assuming one exact block is mandatory. Portal frames occupy multiple blocks, and final linking can depend on the positions of nearby existing portals.
Before building a long-distance portal route
- Convert the destination X/Z coordinates.
- Travel close to the calculated target in the other dimension.
- Check for existing portals nearby before creating a new one.
- Test both directions after activation before relying on the route.

Frequently asked questions
Do I divide Nether coordinates by 8?
No. To go from the Overworld to the Nether, divide Overworld X and Z by 8. To go from the Nether to the Overworld, multiply Nether X and Z by 8.
Does the Y coordinate also use the 8:1 scale?
No. The common coordinate conversion applies to X and Z. Y is not divided or multiplied by 8 by this calculator.
Will the calculated coordinates guarantee that two portals link?
No. They are a strong starting point, but existing portals, exact placement and Minecraft's portal-linking search can affect which portal is selected.
