Minecraft Nether Calculator
Link portals without guessing: one block traveled in the Nether equals eight in the Overworld. Convert coordinates both ways.
1 block in the Nether = 8 blocks in the Overworld (horizontal only; Y stays the same).
How to use
- Choose the direction (Overworld to Nether or back).
- Enter X and Z.
- Build your portal at the converted coordinates.
Examples
Overworld base at 800, 64, -1600
Output: Nether portal at 100, -200 (any safe Y).
Frequently asked questions
Does Y change?
No. Only X and Z scale by 8. Build the Nether portal at a safe Y (ideally above the lava ocean, below the ceiling).
Java or Bedrock?
The 8:1 ratio is the same in both editions.
