FAQ
FAQ
How does the Minecraft portal coordinate ratio work?
One block in the Nether equals eight blocks in the overworld, so overworld coordinates are divided by 8 and Nether coordinates are multiplied by 8.
Does the Y coordinate change when converting?
No. Only X and Z are converted; the Y (height) stays the same in both directions.
Why do my portals link to the wrong place?
Portals link to the closest existing portal within range. Use these coordinates, then let the game snap your new portal to the nearest chunk center.
Can I build a portal at any coordinate?
Yes, but for a guaranteed two-way link build the overworld portal at the exact converted spot and keep it clear of nearby portals.
How do I travel long distances quickly in the Nether?
Building ice or boat highways along Nether coordinates lets you cover eight times the overworld distance for the same effort.
